Constraining the composition and physics of active galactic nuclei with computer modeling.
(2007)
We present analysis from simultaneous FUSE, ASCA, and EUVE observations, as well as a reanalysis of archival HST spectra, from the extreme Narrow-line Seyfert 1 Galaxy RE 1034+39 (KUG 1031+398). RE 1034+39 has an unusually ...
NLTE synthetic spectra and light curves of type Ia supernovae.
(2000)
I have modeled the spectra of Type Ia supernovae with a detailed, non-local thermodynamic equilibrium (NLTE) model atmosphere and radiative transport code, PHOENIX. I have modeled spectra of the normal, Type Ia supernova, ...
Fabrication and characterization of ordered arrays of nanostructures.
(2005)
In this thesis, a combination of bottom-up and top-down approaches is explored to fabricate ordered arrays of nanostrucutures. The bottom-up approach involves the growth of self-organized porous anodic aluminum oxide (AAO) ...
Search for magnetic monopoles possibly produced by proton-antiproton collisions at the Tevatron collider.
(2002)
Magnetic monopoles can be used to explain the quantization of electric charge, and are predicted by gauge field theory. If monopoles exist, they could have been produced by the proton-antiproton collisions at the Tevatron ...
Electrification and lightning in simulated supercell and non-supercell thunderstorms.
(2000)
Three parameterizations of a noninductive graupel-ice mechanism and various strengths of inductive graupel-droplet charging were tested. For a given storm type, the charge distribution and lightning produced by the different ...
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 ...
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, ...
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, ...
Cosmology with a Dark Refraction Index
(2009)
In this dissertation we review Gordon's optical metric theory, generalize it, and apply it to modern cosmology.
Multiwavelength analyses of a small sample of nearby spiral galaxies: The radio and X-ray connection.
(2006)
Included is a preliminary report on radio analyses of M101 and NGC 3184. The deep radio observations of M101 yield 28 compact radio sources. A shorter set of observations for NGC 3184 yield the detection of 10 radio sources. ...
