(2019-07-25)Department: AstrophysicsThe Kilodegree Extremely Little Telescope (KELT) is an ongoing, wide-field, all-sky, time-domain photometric survey built to discover new transiting extrasolar planets of high scientific value orbiting bright host stars. ...
-
(2020-04-03)Department: AstrophysicsThe light curve has taken on a new importance in the field of astrophysics in the 21st century. Next generation telescopes such as the Vera C. Rubin Observatory and the Wide Field Infrared Survey Telescope (WFIRST) will ...

CHARACTERIZING OPEN CLUSTERS AND SPECTROSCOPIC ECLIPSING BINARIES WITH MACHINE LEARNING FRAMEWORKS (2023-07-18)Department: AstrophysicsIn recent years there has been an explosion of data from space-based and ground-based astronomical surveys. This has led to the necessity of moving away from single-use, boutique analyses to flexible automated data analysis ...
-
(2022-03-27)Department: AstrophysicsThere is a large-scale structure to the Universe, known as the cosmic web. Galaxy Clusters, consisting of hundreds to thousands of galaxies, form along and at the nodes of the cosmic filaments that make up this web. This ...
-
(2022-08-01)Department: AstrophysicsIn this thesis, we summarize work in two main areas: the development of millimeter-wave detectors for next-generation Cosmic Microwave Background (CMB) experiments and an initial study pioneering the use of CMB experiments ...

Constraining the Galaxy-Halo Connection Through Accurate Modeling of Small-Scale Galaxy Clustering (2022-03-23)Department: AstrophysicsThe Universe consists of structures of a wide variety of physical sizes. Over the last few decades, astronomers have succeeded in extensively cataloging this structure, both at the (relatively) small scales of stars within ...
-
(2020-08-24)Department: AstrophysicsSolar coronal jets are small-scale, energetic eruptions, characterized by a column-like spire and a bright, dome-shaped base. Jets are often associated with notable changes in the underlying photospheric magnetic field ...
-
(2022-03-29)Department: AstrophysicsOver the past 14 billion years, the Universe has evolved from a state of nearly uniform density into a complex web of structure. Slight perturbations in the initial density field grew over time via gravity, resulting in ...
-
(2021-08-23)Department: AstrophysicsThe lifespan of a galaxy is punctuated by both mergers and flybys, yet most methods to track the galaxy assembly history within a cosmological simulation are designed to identify only mergers. Here, we present the full ...
-
(2022-03-27)Department: AstrophysicsM-dwarfs have the lowest mass, size, luminosity and temperature of main sequence stars and also make up the majority of the total number of stars in our Milky Way galaxy. However, since the first exoplanet systems that ...
-
(2022-08-24)Department: AstrophysicsUnderstanding how structures in the universe form and grow under the influence of gravity is fundamental to our understanding of how the universe we observe came to be. However, simulations of dark matter, which are one ...
-
(2022-11-23)Department: AstrophysicsWe investigate various methods of grouping halo mass accretion histories from a cosmological N-body simulation and the resulting two-point spatial bias of each population. While several authors have used the time at which ...
-
(2023-03-24)Department: AstrophysicsConstraining the connection between the galaxy properties and the dark matter halos they reside in is a powerful tool for understanding the processes responsible for galaxy formation. While the stellar-to-halo mass relation ...
-
(2022-03-30)Department: AstrophysicsBinary stars serve as the astrophysical laboratory in the extraction of stellar and orbital parameters and as calibration sites for stellar evolution theory. These systems come in three flavors, spectroscopic eclipsing, ...
-
(2022-03-29)Department: AstrophysicsThe stellar life cycle plays an important role in polluting the universe with heavy elements essential for life. This dissertation focuses on two different stages of a star’s life cycle – one of which allowed for multicellular ...
-
(2021-07-09)Department: AstrophysicsOverall, there has been growing progress in the astrophysical literature towards the characterization of young stellar evolution phenomenon. The use of sensitive, near-infrared observations continues to unravel these ...
-
(2021-03-16)Department: AstrophysicsRV Tauri variables are luminous pulsating supergiant stars (~10^3 Lsun) with pulsation periods between ~20--150 days and extend the period--luminosity relation of Type II Classical Cepheids. In addition to pulsational ...
-
(2023-03-24)Department: AstrophysicsGalaxy formation theory encompasses a wide range of physical mechanisms that contribute to the growth and evolution of galaxies. First, we study the present-day connection between galaxy morphology and angular momentum ...
