CMB-S4 Detector Development & SPT AGN Monitoring System
(2022-08-01)
In 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 ...
Stellar Evolution at the Crossroads: Resolving the Nature of RV Tauri Variable Systems Using Unprecedented Observations From the Kepler and XMM-Newton Space Telescopes
(2021-03-16)
RV 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 ...
Analyzing Exoplanet Survey Methods Using Massive Datasets: Transit and Microlensing Light Curves
(2020-04-03)
The 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 ...
A High-Performance, Catalog-Driven Approach to Light Curve Extraction for Wide-Field Photometric Surveys
(2019-07-25)
The 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. ...
Modeling the Dependence of Galaxy Quenching on Stellar, Baryonic and Halo Mass in the ECO Survey
(2023-03-24)
Constraining 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 ...
CHARACTERIZING OPEN CLUSTERS AND SPECTROSCOPIC ECLIPSING BINARIES WITH MACHINE LEARNING FRAMEWORKS
(2023-07-18)
In 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 ...
Understanding the Role of Angular Momentum and Supermassive Black Holes in Shaping Present-Day Galaxies
(2023-03-24)
Galaxy 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 ...
Determining the Acceleration Mechanism and Magnetic Topological Structure of Coronal Jets: Evidence for Multiple Acceleration Mechanisms
(2020-08-24)
Solar 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 ...
thornado-Hydro, xCFC: A Discontinuous Galerkin Hydrodynamics Solver for General Relativisitc Core-Collapse Supernova Simulations
(2024-03-25)
Modeling core-collapse supernovae (CCSNe) has been an on-going effort since the 1960s. Despite advances in physics theory, physics experiments, and technology, consistent, multi-dimensional CCSN explosions are still difficult ...
