Various Topics in Type Ia Supernovae
(2019-05-11)
This work takes two approaches to increasing our understanding of type Ia supernovae. The first part uses observations to study their spectral evolution and diversity. The second part uses modeling to investigate a potential ...
Discovery and Classification of New Circumstellar Disks from the AllWISE Catalog with Disk Detective
(2019)
In its five years since launch, DiskDetective.org has led to many new discoveries in the field of circumstellar disks. In my dissertation, I present two major emphases of the project: statistical characterization of infrared ...
Measurement of ggF and VBF Higgs boson production cross-sections in the H->WW*->evmv decay channel from pp collisions collected with the ATLAS detector at the LHC
(2019-12)
This thesis describes measurements of the inclusive Higgs boson production cross-sections via gluon-gluon fusion (ggF) and vector-boson fusion (VBF) through the H->WW*->evmv decay mode, using proton-proton collision data ...
III-V and Thin Film Photovoltaics for Extraterrestrial Application
(2019)
Photovoltaic power is one of the few options available for electrical devices stationed outside of our atmosphere. As the satellite market turns to smaller satellites based on the CubeSat and SmallSat form factor, these ...
BARYON CONTENT TO THE OUTSKIRTS OF LOW-TEMPERATURE POOR GALAXY GROUPS
(2019-12-05)
Little is known concerning the overall properties of galaxy groups, especially at large radii. A better understanding of them will constrain numerical simulations regarding their formation and evolution, as well as reveal ...
The Early Instability Scenario for Planet Formation in the Solar System
(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 ...
Search for vector-like quarks and dark matter in mono-top events in proton-proton collisions with the ATLAS detector
(2019-05-10)
This dissertation describes a search for events with one top-quark and large
missing transverse momentum in the final state. Data collected during
2015 and 2016 by the ATLAS experiment from 13 TeV proton-proton collisions ...
A High Cadence Study of Stellar Variability: Searching for Habitable Planetary Companions Orbiting White Dwarfs with the DECam Minute Cadence Survey
(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 ...
Experimental Study of Cs Isotropic and Anisotropic Polyatomic Rydberg Molecules
(2019-08-22)
In this thesis, we investigate few-body physics and many-body physics of ultralong-range Rydberg molecules. Ultralong-range Rydberg molecules are formed through scattering processes between Rydberg electrons and ground ...
Baryogenesis Scenarios for Natural Supersymmetric Particle Physics Models
(2019-12-06)
Supersymmetric models with radiatively-driven electroweak naturalness require a light higgsino of mass ∼ 100 − 300 GeV. Naturalness in the QCD sector is invoked via the Peccei-Quinn (PQ) axion leading to mixed axion-higgsino ...
