Abstract:

We are at a time in technological development where educational pedagogy must change to adapt to new and emerging technology and to the global connectedness of people and tools. With remote education a commonplace thing, in part necessitated by the global pandemic, and made possible by the current state of technology, it is time to rethink educational methods at the institutional and personal levels. Science education must be a critical focus of educational policy and reform as recent historical events have highlighted the lack of scientific understanding and critical thinking in the general p

Abstract:

Pleiades Visions is a three-movement work for organ solo inspired by indigenous music and mythology associated with the Pleiades (Seven Sisters) star cluster. Three cultural groups are represented in Pleiades Visions. The first movement, entitled "Uluru," draws from Australian Aboriginal music and mythology. The second movement, entitled "...life on other worlds," is based loosely on a Quechan (Yuman) Indian song. The concluding movement, entitled "Mauna Kea," is inspired by the opening lines of the Kumulipo, a creation chant of the Native Hawaiian culture. The source material for Pleiades Vis

Abstract:

The search for exoplanets has gone from the realm of speculation to being one of the most prolific topics of modern astronomy in the space of just 20 years. In particular, the geometric alignment of transiting exoplanets provides the added opportunity to measure a host of properties of these systems, including studies of planetary atmospheres. The vast majority of known transiting exoplanets to date were found using dedicated ground-based surveys such as the SuperWASP project. Such enterprises comprise of multiple small telescopes designed to perform high-precision photometry over a wide field

Abstract:

The study of variable stars is extremely important to the astronomical field of scientific research. Variable stars must be methodically studied, usually by amateur astronomers over a long period of time, in order to provide professional astronomers important data that allows them to further analyze variable star behavior.Variable stars are unique because their pulsation produces visible changes in luminosity. This pulsation allows amateur astronomers to visually observe and identify variable stars. This type of research and study is special because amateurs can make a real contribution to the

In 2015, a gravitational wave (GW) signal from a binary black hole merger passed through the arms of the US-based Advanced LIGO (aLIGO) interferometers, resulting in the first direct detection of gravitational waves. This long-awaited observation made worldwide news one hundred years after Einstein first predicted the existence of GWs in 1916. Since the first detection, four more binary black hole inspiral events have been detected, as well as the ground-breaking GW observation of a binary neutron star inspiral. To detect these signals, ground-based GW detectors like aLIGO and the French-Itali

Almost half of all graduate students leave their doctoral programs without finishing. Who leaves, taking which skills and strengths with them, is still poorly understood, however, because it is hard to measure exactly what graduate students learn in their doctoral programs. Since the expertise required of a PhD holder is highly dependent on discipline, the development of a better understanding of graduate education and attrition requires studying the process at the departmental level.This is a qualitative study of the cultural values and norms of academic astronomy, as transmitted through the

Abstract:

The interest on exo-planetary systems has been growing for the last years, due to the improvements on the observational techniques used to detect extra-solar planets. According to current theories, protoplanets-disc interaction plays a major role in determining the final masses and orbits of the newly born planets, through the protoplanets migration processes. The formation of giant planets (Jupiter like) in particular should be contextual to their quick migration on a time-scale in the order of 10^5 years. Such a time-scale should be smaller by an order of magnitude than that of gas accretion

Abstract:

The study of the nucleosynthesis of the light elements, Lithium, Beryllium and Boron, plays a key role in understanding of several astrophysical problems related to cosmology as well as to stellar structure and evolution. Moreover, the knowledge of their abundances can be a precious tool for the investigation of the inner stellar structure, especially to understand the mixing processes in stellar plasma. These elements, LiBeB, are mainly destroyed in stellar interior through (p,alpha) reactions induced at temperature of the order of 106 K, corresponding to the Gamow energy EG of a few keV's

Post 2005, the largest optical telescope in the Southern hemisphere, known by its acronym, SALT, was constructed in RSA. It is expected that by 2024, this country will host the largest array of radio telescopes in the world, the Square Kilometre Array (SKA). It could be argued that RSA is at the forefront of modern cosmological research. This exponential growth in the field of astronomy has resulted in local astronomical bodies and un

Abstract:

Binary systems can evolve into immensely different exotic systems such as blue straggle stars (BSSs), yellow straggler stars, cataclysmic variables, type Ia supernovae depending on their initial mass, the orbital parameters and evolution. The aim of this thesis is to understand the demographics of post-mass-transfer systems (BSSs, white dwarfs and blue lurkers) present in the open clusters and how they are formed. First, we identified the cluster members using Gaia EDR3 data in six open clusters. Two of the clusters, M67 and King2, were studied in detail using UVIT, Gaia, GALEX, 2MASS

Abstract:

The evidence supporting the presence of Dark Matter in the universe ranges over many length scales: from the rotational curves within galaxies that cannot be explained only by the dust and other visible component to the anisotropies in the cosmological microwave background that sets the most precise quantification for the DM content in the universe at 26.8% of the energy density. One of the candidates for DM with the most theoretical support is a family of particles that appear in extensions of the Standard Model of Particles. These new particles, known as Weakly Interacting Massive Particles

Abstract:

In this thesis we have studied bar formation and evolution using N-body simulations. We have focused on the effect of bulge mass and concentration on bar formation and evolution, and derived a new bar formation criterion. We also tested the criterion with observations collected from literature. We then investigated the effect of bulge mass on bar pattern speed since observations do not give a clear idea of the nature and origin of slow and fast of bars in galaxies. Bars also a potential candidate for changing the dark matter profile in the central regions of galaxies as they transports a

Abstract:

Evolution of galaxies is a phenomenon that affects the formation and composition of galaxies, and the intergalactic medium. It is mediated by processes that establish a symbiotic relationship between a galaxy and the surrounding circum-galactic medium (CGM) by enabling the exchange of mass, momentum, energy, and metals between the two. For star-forming galaxies, one side of the exchange is driven by galactic outflows (GOs) emerging from supernovae explosions (SNes). GOs posses a complex, multiphase structure which covers several orders in magnitudes of density and temperature. A complete

Abstract:

Дисертація присвячена проведенню повного огляду Північного неба з метою пошуку джерел спорадичного радіовипромінювання в декаметровому діапазоні довжин хвиль (далі – Огляд). Проаналізовані переваги та недоліки декаметрового діапазону при проведенні такого дослідження. Розглянуті пошукові огляди таких джерел, що проводилися на інших радіотелескопах та на більш високих частотах радіодіапазону. Також розглянуті різні типи радіочастотних завад, що імітують сигнали космічної природи. Були проведені необхідні радіоастрономічні спостереження на УТР-2, отримані дані оброблені спочатку програмами ав
