Abstract:

Five research areas have been the focus of the scientific work of the Specola Vaticana (Vatican Observatory) over the past twenty years: planetary sciences, stellar astronomy, extragalactic astronomy, cosmology, and the development of the Vatican Advanced Technology Telescope (vatt). The choice of research program is left to the individual astronomers, all of whom work closely with lay collaborators around the world. Notable, especially in connection with the vatt, is the close coordination of the Specola with the Steward Observatory of the University of Arizona. One unique strength of the Specola is its independence from short-term funding requirements. As a result of its stable funding, Specola astronomers can engage in long-term research programs such as surveys of meteorite properties, exoplanets, stellar clusters, and galaxy clusters, which may take ten or more years to come to fruition. In this way the Specola complements the large research programs of contemporary astronomy.

Abstract:

Johann Georg Hagen, the first Jesuit director of the Vatican Observatory, carried out an abundant correspondence with other directors of Jesuit observatories between 1906 and 1930. Letters of his correspondents preserved at the Vatican Observatory and a few of his letters at other observatories provide interesting information about the work and problems of Jesuit astronomical observatories at that time. Letters survive from observatories in Europe, North America, Asia, and Australia. A short presentation is given concerning the relationship between Hagen and the other directors and the contents of the correspondence.

Abstract:

Starting on the 10th of June, 1986, the staid and quiet halls and courtyard and corridors, including the giant circular staircase designed by Bernini for the little donkeys that carried Popes to their quarters in the summer palace, echoed to the swift patter of lightfooted students and the buzz of their conversations as 17 young men and 8 young women met at the first Vatican Observatory Summer School in Astronomy and Astrophysics at Castel Gandolfo.These 25 scholars had been chosen from a list of 135 candidates at university and graduate school campuses all over this planet. More than 30 candidates were rejected for “excellence”; they were judged to be too far advanced for admission to the classes on Galaxies and Dark Matter and to those on Spectral Classification and on Instrumentation for Photometry and Image Processing. The classes were aimed at students just beginning or planning immediate entrance into graduate level classes; the School was not planned for “new Ph.D.s,” for “post-docs,” or for those already well into thesis work. Criteria for admission included academic grades, recommendations of university professors, plus personal statements from the candidates on reasons why they felt they wanted to attend the sessions of the school. Applications were studied by faculty and staff members and results were announced in January, giving students some four months to arrange their travel and home commitments so they could be free to respond to the school bells on June 10.

Abstract:

AbstractTwo seemingly incongruous components have come together about every two years: the serene terraces of the Pope’s summer residence at Castel Gandolfo, and the noisy exuberance of 25 beginning-level graduate students. Add in a small faculty of first-rate professors and a resourceful local support team, and one has the ingredients for the month-long Vatican Observatory Summer Schools. The eighth School takes place in the summer of 2001, and its goals are the same as when the series started in 1986: to encourage and motivate a mix of young people from industrialized and developing countries who are at critical moments of their research careers, and to make a small, but significant contribution to the progress of developing countries by exposing some of their most talented young citizens to people involved in high quality research in astrophysics. This account outlines the nature of the Schools, their follow-up, and something of how the spirit of sharing of personal and institutional resources is achieved.

Abstract:

Abstract We report the discovery of activity emanating from (18916) 2000 OG44 (alternately designated 1977 SD), a minor planet previously reported to be both an extinct comet and an asteroid on a cometary orbit. We observed 2000 OG44 with a thin tail oriented towards the coincident antisolar and antimotion vectors (as projected on the sky) in images we acquired on UT 2023 July 24 and 26 with the Apache Point Observatory 3.5 m Astrophysical Research Consortium telescope (New Mexico, USA). We also include observations made in Arizona with the Vatican Advanced Technology Telescope at the Mount Graham International Observatory and the Lowell Observatory Lowell Discovery Telescope near Happy Jack. We performed dynamical simulations that reveal 2000 OG44 most likely originated in the Oort cloud, arriving within the last 4 Myr. We find 2000 OG44, which crosses the orbits of both Jupiter and Mars, is at present on an orbit consistent with a Jupiter-family comet. We carried out thermodynamical modeling that informed our broader diagnosis that the observed activity is most likely due to volatile sublimation.

Abstract:

The spectre of Communist expansion as a result of the Second World War represented for Pope Pius XII one of the greatest concerns. The unambiguously pro-Soviet orientation of the Czechoslovak government in exile and the crucial influence of Communists in the inner architecture of the restored state convinced the Holy See that Czechoslovakia was already in 1945 fully absorbed into the Soviet sphere of influence. This fact strengthened the Pope’s conviction of the necessity to resume relations with Prague as soon as possible and to send a nuncio there who would provide reliable information and protect the interests of the Church threatened both by open persecution and by propaganda manoeuvres in favour of a “progressive Catholicism”. The importance of the relations with Czechoslovakia stood out also in the international perspective, in which Czechoslovakia, in contrast to Poland or Hungary, seemed to be the last observatory still accessible to the Vatican diplomacy in the whole East-Central Europe. The year 1947 represented a caesura in the relations between the Holy See and Czechoslovakia. In the international context, this year was generally perceived by the Vatican as a definitive reinforcement of the Communist regimes in Eastern Europe. In the Czechoslovak framework, the greatest importance was ascribed to the political crisis in Slovakia in autumn 1947, during which the Communists definitively took over the political power in Slovakia. The lost struggle over the predominantly Catholic Slovakia, that for some time had been considered by the Vatican one of very few hopes for the defence of Christian interests in the Republic, was perceived by the Holy See as a dominant breakthrough on the way to the total Communist transformation of Czechoslovakia. While in the immediate post-war period the Holy See had tried to come to terms with Czechoslovakia also at the price of some compromises, in winter 1947/1948 the last hopes for a diplomatic solution vanished and were replaced by the conviction that in the confrontation with Communism not diplomatic, but spiritual weapons — prayer, testimony, martyrdom — were of crucial importance.

Abstract:

Érigée canoniquement en 1785, avant d’être supprimée par les nazis en 1934, la nonciature de Bavière représente un observatoire privilégié pour la diplomatie vaticane au lendemain de la guerre. De mai 1917 jusqu’à son départ pour Berlin en août 1925, le nonce apostolique à Munich n’est autre que Mgr Eugenio Pacelli (1 876-1958), le futur Pie XII, considéré à l’époque comme le meilleur diplomate du Saint-Siège. Confronté à la montée des idéologies extrêmes, il fait preuve de réalisme et de modération lors de la révolution spartakiste de 1918-1919. En dépit de sa sympathie personnelle pour les milieux conservateurs fédéralistes, il se refuse à pratiquer la politique du pire et garde ses distances à l’égard des tendances séparatistes. Le concordat avec la Bavière (29 mars 1924), qu’il mène à bien malgré les critiques du cardinal Gaspard, représente un «succès personnel». En novembre 1923, il insiste sur le «caractère anticatholique» des manifestations qui font suite au putsch manqué de Hitler.

Abstract:

La presente publicación XXIX, número 2, de revista Persona y Sociedad, cuenta con cinco artículos y tres reseñas. En el primer artículo, titulado “Análisis crítico del concepto de valores absolutos relativamente absolutos”, Isabel Ruiz-Gallardón se plantea analizar las tesis del profesor Pedro Schwartz sobre el concepto de ‘valores absolutos relativamente absolutos’, que fueran divulgadas en su ensayo En busca de Montesquieu. La democracia en peligro. En esta dirección, la autora “se plantea una reconsideración de la aplicación que realiza Schwartz del método hipotéticodeductivo de Karl Popper al ámbito de los valores”. María Celia Duek nos presenta otro artículo con un fuerte carácter teórico. En “Campo de batalla teórico: teorías posmodernas y posmarxistas versus marxismo”, la autora analiza cómo desde el surgimiento de la sociología clásica con Max Weber y Emile Durkheim, “toda la teoría social dialoga con el marxismo o la emprende contra él”. En particular, revisa la crítica que experimentó la teoría marxista durante los últimos 20 o 30 años del siglo XX “por parte de las reflexiones posmodernas y posmarxistas, que lograron erigirse como teorías sociológicas hegemónicas”. La autora pretende mostrar “cómo durante esos años la teoría marxista fue ninguneada y sus conceptos fueron desplazados del ámbito académico por nuevas nociones, presuntamente más adecuadas para explicar la sociedad actual”. El tercer artículo, de Alejandro Espinosa, pertenece al ámbito de la sociología de la ciencia, y lleva por título “Asignación de científicos en el observatorio astronómico Atacama Large Millimeter/Submillimeter Array (ALMA): lógica virtual, sociomaterialidad y régimen de control en la ciencia”. Este trabajo busca dar cuenta de los “procesos de asignación de tiempos de observación en el observatorio astronómico ALMA en Chile”. Con este objetivo, se investiga la asignación de científicos en este observatorio, y al mismo tiempo “se señala cuáles son las instancias en que los científicos se coordinan, cómo se utilizan ciertos dispositivos para facilitar los procesos de selección y de qué forma ello conlleva un dominio particular del régimen”. Los dos artículos siguientes aplican una metodología cualitativa para analizar dos problemáticas concretas en Valparaíso y la Región Metropolitana de Santiago. “Discapacidad física e identidad: elementos emergentes en la experiencia de vida en el Gran Valparaíso”, de Sergio Marambio, se plantea como objetivo principal “analizar los procesos de construcción identitaria de las personas en situación de discapacidad física del Gran Valparaíso”, utilizando la “tradición fenomenológica”. Como resultado, “la identidad se configura en torno a tres grandes dimensiones transversales: cuerpo, cultura y contexto social, las que se encuentran interrelacionadas”. En este texto “se presenta la identidad de una persona con discapacidad física como una estructura eminentemente social, en constante cambio y configurada en torno a la superación de barreras sociales, culturales, ideológicas, entre otras”. Por su parte, el artículo de Héctor Rivera titulado “Procesos de movilidad social de profesionales de estratos socioeconómicos medios de la Región Metropolitana de Santiago de Chile”, propone investigar “la influencia del reconocimiento socio-laboral en los procesos de movilidad social de los profesionales de estratos socioeconómicos medios de la Región Metropolitana de Santiago de Chile”. Este trabajo se aborda desde la dimensión del reconocimiento socio-laboral, lo que “se debe a que la teoría revisada sobre movilidad social se refiere mayoritariamente a cuantificaciones en la distribución del bienestar económico y social de una persona o grupo en un tiempo determinado, entregando resultados muy relevantes y útiles, pero que no abordan la dimensión significativa del problema”. Este volumen se cierra con tres reseñas. La primera, realizada por Juan Pablo Espinoza, destaca la importancia de la publicación Teología de los signos de los tiempos latinoamericanos. Horizontes, criterios y métodos (Azcuy, Schickendantz, Silva, 2013). Frente a la pregunta de ¿por qué realizar una teología de los tiempos en América Latina?, se responde que hay un reconocimiento de que “en América Latina se ha dado una recepción teológica creativa, original, selectiva, inacabada del Concilio Vaticano II”. La segunda reseña, preparada por Gustavo Sánchez, aborda el texto Economía política del fracaso. La falsa modernización del modelo neoliberal (Mayol, Ahumada, 2015). Sánchez destaca que este libro “constituye una contribución fundamental para comenzar a desnaturalizar el modelo chileno, evidenciar cuáles son sus discursos ideológicos legitimadores y aportar las bases para elaborar un lenguaje propio de ‘la crítica’, uno que pueda incorporarse a la disputa sobre qué mantener y qué reemplazar”. Finalmente, Vivian Díaz elabora la tercera reseña, del libro La construcción social de las demencias en las personas mayores de la Región Metropolitana, Chile (Guajardo, Tijoux, Abusleme, eds., 2015). Se trata de una investigación que “nos sitúa frente a la temática de la demencia y da cuenta de las construcciones sociales que se tejen en relación a esta, considerando la vivencia y narrativas de quienes están en contacto cotidiano con los adultos mayores que han sido diagnosticados con esta enfermedad, como son los familiares, cuidadores, entornos comunitarios e institucionales”.

Abstract:

Abstract We report I-band photometric observations of the radio-detected M9.5 dwarf BRI 0021-0214, obtained with the Galway Ultra Fast Imager (GUFI) on the 1.8m Vatican Advanced Technology Telescope VATT at Mt. Graham International Observatory, Arizona. In total, 19 hours of observations over a 73 day baseline were obtained. BRI 0021-0214 was shown to exhibit modulated emission with a period of 3.052 ± 0.004 hours with a mean amplitude variability of 0.0044 mag. When combined with rotational velocity data obtained from previous work, our newly discovered rotation period gives an inclination angle of 51.7$^{+5.0}_{-4.5}$ degrees for the rotation axis of BRI 0021-0214 relative to our line of sight. Previous studies have reported that the most plausible cause for optical variability from this dwarf is a consequence of suspended co-rotating dust clouds in its atmosphere. However reports of enhanced Hα and intermittent coherent radio emission suggest the possibility of auroral activity in its magnetosphere. Further, more coordinated multiwavlength observations of this dwarf could fully resolve the nature of this elusive rapid-rotator object’s observational properties.

Digitisation of astronomical plates and their integration into the International Virtual Observatory." Astronomy & Astrophysics, April 30, 2024. http://dx.doi.org/10.1051/0004-6361/202348793.

Full text

Abstract:

The Archives of Photographic PLates for Astronomical USE (APPLAUSE) project is aimed at digitising astronomical photographic plates from three major German plate collections, making them accessible through integration into the International Virtual Observatory (IVO). Photographic plates and related materials (logbooks, envelopes, etc.) were scanned with commercial flatbed scanners. Astrometric and photometric calibrations were carried out with the developed PyPlate software, using Gaia EDR3 data as a reference. The APPLAUSE data publication complies with IVO standards. The latest data release contains images and metadata from 27 plate collections from the partner institutes in Hamburg, Bamberg, and Potsdam, along with digitised archives provided by Tautenburg, Tartu, and Vatican observatories. Altogether, over two billion calibrated measurements extracted from about 70,000 direct photographic plates can readily be used to create long-term light curves. For instance, we constructed the historic light curve of the enigmatic dipping star KIC\,8462852. We found no evidence of previously assumed variations on timescales of decades in our light curve. Potential uses of APPLAUSE images for transient sources can be appreciated by following the development of the nova shell of GK\,Per (1901) over time and the change in brightness of two extragalactic supernovae. The database holds about 10,000 spectral plates. We made use of objective prism plates to follow the temporal changes of Nova DN Gem through 1912 and 1913, highlighting an outburst in early 1913.

Abstract:

Constraining the coplanarity status of very low mass (VLM) tight binary systems provides valuable information towards understanding the dominant mechanisms in star and planetary formation at the lower end of the initial mass function. We sought to constrain the $v sin i$ degeneracies of two nearby tight VLM binary systems, 2MASS J0746+20AB and 2MASS J1314+13AB, by independently determining each companion's rotational period and so characterize each system's spin-orbit alignment. Long observational baseline high cadence $I$ band photometry data were obtained for both systems using the Galway Ultra Fast Imager (GUFI) on the Mount Graham International Observatory's Vatican Advanced Technology Telescope. Previously known rotational periods determined in other passbands were used as a basis for recovering additional periodic modulations in the time-series data. Using the known rotational period of 3.32 hours for 2MASS J0746425+200032A, we recovered an underlying periodic modulation of $2.14 0.11$ hours, which we associate with 2MASS J0746425+200032B. Breaking each components' $v sin i$ corresponds to equatorial inclination angles of 32 $ $ 4 degrees and 37 $ $ 4 degrees for components A B respectively. We recover a weaker 2.06 pm 0.05 hours modulation separate from the known 3.79 hour signature for J1314203+132001B, which we associate with J1314203+132001A. We place a lower limit on J1314203+132001A's equatorial inclination angle to be in the range of 24.5$^ $ degrees, which deviates from the system's orbital plane previously determined to be 49.34$^ $ degrees. We confirm long term, consistent periodic modulations from both binary systems and report the first definitive rotational period for J1314203+132001A of 2.06 pm 0.05 hours, in addition to coplanarity to within 10 degrees in the spin-orbit alignment of the 2MASS J0746425+200032AB system. The lack of separate $v sin i$ values for the 2MASS J1314203+132001AB system limits a definitive assessment but best estimates suggest coplanarity to be unlikely.
