Abstract:

In the 1920s, during the first archaeological excavations at Uaxactún, Petén, Guatemala, an architectural complex named Group E was interpreted as an ancient Maya astronomical observatory, intended specifically for sighting the equinoctial and solstitial sunrises. In the following decades, a large number of architectural compounds with the same configuration have been found, most of them in the central lowlands of the Yucatan peninsula. The multiple hypotheses that have been proposed about the astronomical function of these complexes, commonly designated as E Groups, range from those attributi

Abstract:

<em>This study investigates the alignment of mosques in Gumel Town, Nigeria, with the apparent movement of the sun, focusing on the accuracy of their orientation towards the Qibla. A mixed-methods approach, incorporating surveys, interviews, and astronomical observations, revealed significant deviations in mosques' orientation. These discrepancies are attributed to the reliance on traditional methods, limited astronomical knowledge, and cultural/architectural influences. The findings emphasize the need for education and awareness on precise Qibla direction and astronomical methods in mosque de

Abstract:

The AP-CA-18 archaeological site of Calçoene, located in the northern Brazilian Amazon, has a megalithic arrangement in the shape of an irregular circle, constituting a cromlech with menhirs of azimuths and well-defined zenith angles. From the perspective of current academic astronomy, it prints a strict relationship with the observation of astronomical events, notably equinoxes and solstices. Without intending to interfere in the anthropological studies of the social group that built it, this work, based on cartography and support in geotechnologies, analyzed the shapes, layout, orientation a

Abstract This study applies astronomical analysis to two Vincent van Gogh paintings from the summer of 1888, demonstrating how scientific principles can deepen our understanding of artistic works. While previous research has shown that van Gogh occasionally placed celestial bodies in positions significantly different from their astronomical reality, the analysis of Wheat Field with the Setting Sun and Canal with Women Washing reveals a close alignment with expected astronomical positions. This contrast suggests that van Gogh made conscious decisions about celestial positioning, sometimes prior

Abstract:

Abstract Planets are known to grow out of a star-encircling disk of the gas and dust inherited from an interstellar cloud; their formation is thought to begin with coagulation of submicron dust grains into aggregates, the first foundational stage of planet formation. However, with nanoscale and submicron solids unobservable directly in the interstellar medium (ISM) and protoplanetary disks, how dust grains grow is unclear, as are the morphology and structure of interstellar grains and the whereabouts and form of “missing iron.” Here we show an elementary composite binary in 3D sub-10 nm detail

Abstract:

The object of this study is the background substrate of astronomical frames. To detect and compare the image of an object in a frame with its real image from astronomical catalogs, it is necessary to uniformly distribute the brightness of the background image substrate. Most often, the background alignment of astronomical frames is performed using the hardware calibration method applying the construction of service frames. However, it does not make it possible to eliminate the background from temporary stray light. Therefore, to solve this problem, a procedure has been proposed for brightness

The WSW–ENE alignment of the Greater Stonehenge Cursus appears to have been prefigured by the line of Mesolithic post-holes found in the Stonehenge car park.

The fact that a significant number of henges in western lowland Britain adopt the same broad alignment hints at a very long-lived mental template.

Since these structures are often buried in very large data sets, an algorithm, which can not only recover the manifold but also remove the background noise (or outliers), is highly desirable.

Abstract: A significant aspect revolves around the astronomical positioning detailed in Sage Valmiki's Ramayan. By employing the "Platinum Gold" software, which enables simulation of the celestial sphere, extraction of English calendar dates corresponding to events mentioned in the Valmiki Ramayan, correlating them with planetary positions has been analyzing in the paper first. The findings reveal intriguing dates for significant events in Lord Rama's life, such as his birth, battles, and the completion of his exile. The meticulous alignment of these dates with the narrative in Valmiki's Ramay

Abstract The ASCA instrument uses identical conical foil X-ray mirrors for its four telescopes. One of the major advantages of ASCA’s telescopes is the first time ever use of X-ray imaging over a broad energy band and high throughput for conducting astronomical spectroscopy. Nested thin foil reflectors make possible a large effective area up to 10 keV, even under the tight weight restriction of the ASCA spacecraft. The expected characteristics of the ASCA mirrors are summarized based on ray tracings and pre-flight calibrations. The total effective area of four telescopes at 1 and 7 keV are ~ 1

Abstract:

The Inca oracular sanctuary of the god Pachacama (organizer-energizer of time-space) began its heyday with Tupa Inca Yupanqui ca. 1465 AD, becoming the most important oracular-administrative centre of the coast, and second in importance in all the Tawantinsuyo, "the Inca empire of the four regions". Located on the rainless desert central coast of present-day Peru, the urban complex of adobe and stone buildings has four temples, fourteen structures with ramps, several courtyards and twenty-one edifices, occupying 1,250 acres. The urban layout presents three main alignments that establish its ba

Abstract The Dark Energy Spectroscopic Instrument (DESI) is currently measuring the spectra of 40 million galaxies and quasars, the largest such survey ever made to probe the nature of cosmological dark energy. The 4 m Mayall telescope at Kitt Peak National Observatory has been adapted for DESI, including the construction of a 3.°2 diameter prime focus corrector that focuses astronomical light onto a 0.8 m diameter focal surface with excellent image quality over the DESI bandpass of 360–980 nm. The wide-field corrector includes six lenses, as large as 1.1 m in diameter and as heavy as 237 kilo

Abstract:

Abstract Dome A in Antarctica likely has the best observing conditions on the Earth’s surface in the near-infrared owing to its sky-light background and superior seeing conditions. This work introduces the system design and on-sky performance of the first wide field-of-view near-infrared telescope at Dome A. We present the lens design, tolerance analysis and stray light analysis of the optical system. We then evaluate a preliminary alignment method suitable for daytime use based on visual inspection. Finally, we describe a direct drive motor with maze structures, and an optical system with the

The Newgrange passage tomb is examined for evidence of ‘Neolithic science’. Claims that it incorporated an astronomical alignment, and was constructed using Pythagorean geometry and the megalithic yard are reviewed as are scientific interpretations of its art. A new analysis of the tomb's structure reveals that it was based on a simple geometric shape measurable by a 13.1 m unit of length. The locations of particular motifs and decorated surfaces are shown to conform to the spatial relationships evident in the tomb's form. These are defined in terms of oppositions between left and right, front

This article examines synchronization methods for multi-detector phased systems that integrate spatially distributed transmit–receive nodes into a single coherent structure. The study's primary aim is to determine the technical requirements for temporal, frequency, and phase alignment of the elements, and to analyze the hardware and algorithmic means for achieving them. The relevance of this work is driven by the rapid development of phased arrays and distributed radar and astronomical systems, where even tens of picoseconds of desynchronization lead to significant loss of coherent gain and de

AbstractIt is known that the grid pattern characterizing the city layout of Teotihuacan incorporates two slightly different groups of alignments, skewed approximately 15.5° and 16.5° clockwise from cardinal directions. I argue that these alignments were dictated by deliberate and astronomically functional orientations of the Pyramid of the Sun and the Ciudadela. The two structures recorded sunrises and sunsets on two different sets of dates, allowing the use of an observational calendar composed of intervals that included multiples of 20 days and a 260-day period.

Abstract. We have compiled 37 ice, marine and terrestrial palaeoclimate records covering the last 800 000 years in order to assess the pattern of glacial and interglacial strength, and termination amplitude. Records were selected based on their length, completeness and resolution, and their age models were updated, where required, by alignment to the LR04 benthic δ18O stack. The resulting compilation allows comparison of individual glacial to interglacial transitions with confidence, but the level of synchronisation is inadequate for discussion of temporal phasing.
