Quantifying the Physics and Energetics of Iron Low-Ionization Broad Absorption-Line Quasar Outflows
(2022)
Quasars are among the most luminous and massive objects in the universe. They host an actively accreting supermassive black hole (SMBH) at their centre that can power energetic phenomena that outshine the host galaxy. A ...
Opposite side jet charge tagging and measurement of CP asymmetry parameter sin(2beta) at DO.
(2004)
This dissertation describes the first CP asymmetry parameter sin(2beta) measurement by the DO collaboration, sing the opposite side jet charge tagging algorithm in determining B-flavor. The time integrated measurement ...
Spectrum Formation at Late Times in Type Ia Supernovae
(2015-05-08)
I present a study of radiative transfer effects in type Ia supernovae ranging from 3-4 months to nearly 2 years post-maximum light. I explore several components of spectrum formation, beginning with a semi-analytic model ...
InSb QUANTUM WELL STRUCTURES FOR ELECTRONIC DEVICE APPLICATIONS
(2009)
The electron effective mass is smaller in InSb than in any other III-V semiconductor. Since the electron mobility depends inversely on the effective mass, InSb-based devices are attractive for field effect transistors, ...
Non-LTE effects in supernova envelopes.
(1980)
The Sobolev method has been applied to the solution of the satistical rate equations for multi-level representations of singly ionized silicon and neutral hydrogen for various models of supernova envelopes. The physical ...
Radio-frequency emissions from runaway electron avalanche models compared with intense, transient radio-frequency signals associated with thunderstorms.
(2002)
The results of a one-dimensional model of a runaway electron avalanche, initiated by a high-energy cosmic ray secondary electron, in a thunderstorm electric field are presented. The time-evolution of the electron densities, ...
Radiatively-driven Natural Supersymmetry
(2014-08-15)
Within the framework of supersymmetric theories, a question arises: how can the W, Z, and h masses be so low (∼ 100 GeV) when the superpartner masses are so high (mSUSY > 1−2 TeV)? This is the little hierarchy problem, and ...
Intervalley Scattering in III-V Heterostructures and its Application to Valley Photovoltaic Hot Carrier Solar Cells
(2022-12-16)
The efficiency limit of 33% for a single gap solar cell is not fundamental. Mitigation of thermalization losses which occur when high energy ‘hot’ carriers are only extracted at the same energy as low energy carriers is a ...
Space Application of Novel Solar Cells
(2023-05-12)
Multiple solar cell technologies from three different generations of photovoltaic cells were studied for space applications. The GaAsSb, crystalline first-generation solar cells were studied under low-intensity-low-temperature ...
Measurement of the Top Quark Pole Mass and QCD Radiation in Top Quark Pair Production using Electron-Muon Events with b-Tagged Jets in Proton-Proton Collisions at 7-8 TeV with the ATLAS Detector at the LHC
(2015)
As heavy as an atom of gold but much smaller than a proton, the top quark is the most massive fundamental particle known in the universe and an integral part of current particle physics research. The characteristics of the ...
