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.
Radiative transfer and type Ia supernovae spectra analysis in the context of supernovae factory.
(2005)
We showed the spectrum formation in SNeIa around maximum light to be a multi-layered process involving regions from 5000 km per s to 20000 km per s, interacting not only through scattering but also through pure emission. ...
Measurement of the Double Differential Dijet Mass Cross Section in pp(bar) Collisions at sqrt(s) = 1.96 TeV
(2009)
This thesis presents the analysis of the double differential dijet mass cross section, measured at the DØ detector in Batavia, IL, using pp(bar) collisions at a center of mass energy of √s = 1.96 TeV. The dijet mass ...
Novel phenomena in confined electronic systems.
(2007)
Modern experimental methods have made it possible for physicists to investigate matter in extreme conditions. Two of the most extreme conditions are low temperature and low dimensionality. Fabricated semiconductor or metal ...
A radio and x-ray search for intermediate-age supernovae: Tuning into the oldies.
(2001)
Type II supernovae (SNe) are the cataclysmic and very luminous last stage in the evolutionary track of very high mass stars, resulting in the destruction of the star and the ejection of large amounts of material into their ...
Laser cooling and trapping using Laguerre-Gaussian laser beams.
(2003)
Laser cooling and trapping has led to a revolution in Atomic and Molecular physics. Optical traps created with blue-detuned laser beams are desired for numerous studies. One method of creating such a trap is with ...
Albedos in the Kuiper Belt
(2009)
I have focused my research on the visual geometric albedos of transneptunian objects (TNOs), how the albedo varies with dynamical class, and whether or not it is correlated to orbital parameters. TNOs are among the ...
Absolute-magnitude distributions and light curves of stripped-envelope supernovae.
(2004)
The absolute visual magnitudes of three Type IIb, 10 Type Ib and 13 Type Ic supernovae (collectively known as stripped-envelope supernovae) are studied by collecting data on the apparent magnitude, distance, and interstellar ...
Cold nitric oxide molecules from a Stark guide.
(2005)
One possible technique is the use of a modified straight Stark guide to filter the slow moving molecules from a thermal source. Here I present such a technique and the design of the necessary apparatus. Furthermore, I ...
Spin resolved cyclotron resonance in indium antimonide quantum wells.
(2005)
In this study we looked at spin resolved cyclotron resonance in InSb quantum wells. InSb is an attractive material for this type of work due to its small electron effective mass (0.014 mo), high intrinsic electron mobility, ...
