Measurement of the angular distribution of electrons from W boson decays at D-zero.
(1999)
We present a measurement of the electron angular distribution parameter a2 in W→ en events using data collected by the DO detector during the 1994--1995 Tevatron run. We compare our results with next-to-leading ...
Non-local thermodynamic equilibrium spectrum synthesis of type Ia supernovae.
(1997)
This thesis is broken down into 4 major sections, each highlighting a different way with which to use spectrum synthesis to analyze SNe Ia. Chapters 2 and 3 look at normal SNe Ia and their potential use as distance indicators ...
Abundances in planetary nebulae: An autopsy of low and intermediate mass stars.
(1997)
In this work we report on the results of synthetic thermally pulsing asymptotic giant branch models (TP-AGB) and compare the results to the abundance ratios in a sample of planetary nebulae. We use updated the input ...
Applications of Diatomic Molecules
(2015-05-08)
I present a study and application of diatomic molecules to various uses in the laboratory. It begins with an experiment to trap ultracold nitric oxide, then proceeds to multiple experiments where tellurium is utilized to ...
Hot Electrons and Radial Transport in Saturn’s Inner Magnetosphere: Modeling the Effects on Ion Chemistry
(2012)
The E-ring of Saturn, located just beyond the main rings at four Saturn radii, was known to be made mostly of water and its by-products before the Cassini spacecraft arrived at Saturn in 2005. Since then, Cassini has ...
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, ...
