    • Constraining Dark Matter Through Cosmological Observations 
      Clark, Steven James (2019-07-17)
      While gravitational effects of dark matter are observed at galactic and larger scales, other behaviors are more elusive. Two approaches for extra-solar studies of dark matter interaction are from an energy perspective and ...
    • Cosmology and gravity in the brane world 
      Dent, James Blackman (Texas A&M University, 2005-11-01)
      The cosmology in the Hubble expansion era of the Horava-Witten M-theory compactified on a Calabi-Yau threefold is studied in the reduction to five-dimensions where the effects of the Calabi-Yau manifold are summarized by ...
    • Hints of Universality from Inflection Point Inflation 
      Downes, Sean Donovan (2013-07-25)
      This work aims to understand how cosmic inflation embeds into larger models of particle physics and string theory. Our work operates within a weakened version of the Landscape paradigm, wherein it is assumed that the set ...
    • Lorentz-violating dark matter 
      Mondragon, Antonio Richard (2009-05-15)
      Observations from the 1930s until the present have established the existence of dark matter with an abundance that is much larger than that of luminous matter. Because none of the known particles of nature have the correct ...
    • Low Energy Nuclear Recoil Response in Xenon Gas for Low Mass Dark Matter WIMP Search 
      Sofka, Clement James (2014-04-16)
      Over 80 years of astrophysical observations suggest that the observable luminous matter makes up ≤ 5% of the total energy density in the Universe. The remaining ~ 95% comes from matter and energy that has not been observed ...
    • Making the Dark Matter Connection Between Particle Physics and Cosmology 
      Krislock, Abram Michael (2012-10-19)
      Dark matter has been shown to be extremely abundant in our universe. It comprises about 23 percent of the energy density of the entire universe, which is more than five times greater than the regular matter we already know ...
    • Precision Time Series Photometry and Its Application in Supernova Cosmology 
      Yang, Jiawen (2023-04-17)
      Type Ia Supernovae (SNe Ia) have played an important role in modern cosmology as distance indicators and have led to the discovery of the accelerated expansion of the universe. Such usage of SNe Ia hinges upon the precision ...
    • String Phenomenology in the Era of LHC 
      Maxin, James A. (2010-10-12)
      The low-energy supersymmetry phenomenology for specific classes of string compactifications is investigated given that the low-energy physics may provide a clue as to the structure of the fundamental theory at high energy ...
    • A STUDY OF PROPERTIES OF TYPE IA SUPERNOVA AND THE CALIBRATION OF MULTIBAND PHOTOMETRY 
      Bastola, Deepak 1988- (2012-04-27)
      The peak luminosity of Type Ia Supernova (SN) can be calibrated using a distance independent luminosity parameter called the decline rate parameter (?m15 (B) to get accurate distances to the galaxies. The photometry gathered ...
