AGN and their environment: a multi-wavelength photometric and spectroscopic study of AGN and galaxy clusters, and the co-evolution of AGN and the large scale structures
Mishra, Hora (2022)Active galactic nuclei (AGN) are the central engines hosted by most of the galaxies in the universe and are believed to be actively accreting supermassive black holes. The growth of the central black hole is very closely ... -
Disentangling the Formation Pathways of Protostars
Reynolds Tran, Nickalas (2023-05)Star formation occurs within dense cores within molecular clouds, often associated with filamentary structures. However, there exist isolated instances of star formation, far from nearby forming stars. As a core collapses, ... -
Dwarf galaxies in N-body+SPH simulations
Van Nest, Jordan (2023-12)I present a study of various dwarf galaxies from N-body+SPH simulations in Lambda Cold Dark Matter cosmology. While the science results of this thesis pertain to dwarf galaxies of varying classifications and environments, ... -
The Early Instability Scenario for Planet Formation in the Solar System
Clement, Matthew (2019-05-10)The leading evolutionary model for the outer solar system, an orbital instability between the solar system’s giant planets, has been shown to greatly disturb the orbits of the young terrestrial planets. Undesirable outcomes ... -
Evolution and Stability of Ultra-Wide Trans-Neptunian Binaries
Campbell, Hunter (2023-08-04)This research is focused around the longevity and formation of a class of binaries in the Kuiper Belt called Ultra-Wide Trans-Neptunian Binaries (Ultra-Wide TNBs). The presence of these seemingly fragile binary systems ... -
A High Cadence Study of Stellar Variability: Searching for Habitable Planetary Companions Orbiting White Dwarfs with the DECam Minute Cadence Survey
Dame, Kyra (2019-07)One outstanding question in astronomy is what happens to planetary systems as their host star evolves. Though indirect evidence such as metal polluted white dwarf atmospheres and debris disks around white dwarfs, and recent ... -
High Contrast Imaging of Planet-forming Disks with Extreme Adaptive Optics Systems
Lawson, Kellen (2022)Circumstellar disks serve as benchmark systems to study how and where exoplanets form. With the advent of ground-based extreme adaptive optics (AO) facilities, we have entered a revolutionary era for disk studies. It is ... -
Modeling Stellar Surface Features with High-Precision Photometry
Schutte, Maria (2023)Starspots are a major source of stellar contamination in transmission spectroscopy of exoplanet atmospheres, and the correction for exoplanet analyses depends on the temperature of the starspots and the covering fraction. ... -
An Ultraviolet Survey of the DA White Dwarf Population of the Galaxy
Wall, Renae E. (2023-08-04)DA white dwarfs are the most common type of white dwarf in our Galaxy. Hence, it is important to study the DA white dwarf population as thoroughly as possible. In this dissertation, I present our work using the Galaxy ... -
Understanding Type Ia Supernova Diversity with PHOENIX
DerKacy, James M (2022)Type Ia Supernovae (SNe Ia) are important astrophysical objects. They produce roughly half of the iron group elements found in the universe, the energy they release drives the evolution of galaxies, and their high ... -
THE UNIQUE GEOMETRIES AND ILLUMINATIONS OF PROTOPLANETARY DISKS AND THEIR POTENTIAL EXOPLANETS
Rich, Evan (2019-05-11)The discovery of new protoplanetary disk structures can help reveal the dynamics of the young planetary systems and potentially point to planet formation within the disk. In my dissertation, I present investigations of ...
