    • DARK MATTER MAY NOT BE SO DARK: Testing Massive Primordial Black Hole Dark Matter with Galactic X-Ray Emission 
      McPhaul, Nolan (Vanderbilt University. Dept. of Physics and Astronomy, 2024-04-16)
      Were primordial black holes (PBHs) to exist, they could constitute a significant portion of dark matter in our universe which could be explored through gravitational wave emission, gravitational lensing, and electromagnetic ...
    • Expected Host Galaxy Properties of PTA Detectable Massive Black Hole Binaries 
      Cella, Katharine (Vanderbilt University. Dept. of Physics and Astronomy, 2021-12-06)
      Massive black hole binaries (MBHB) produce gravitational waves (GW) that will be detectable with pulsar timing arrays within the next few years. We determine the properties of the host galaxies of MBHB at the time they are ...
    • Impact of Entropy on Black Hole Astrophysics 
      Chen, Siyuan (Vanderbilt University. Dept. of Physics and Astronomy, 2024-04-18)
      As an irreversible natural process, mergers between two black holes will increase the entropy of the universe. By imposing thermodynamical constraints derived from general relativity and quasi-circular hypothesis, we ...
    • Number density profiles of galaxy groups and clusters in the SDSS 
      Norris, Jackson M. (Vanderbilt University. Dept. of Physics and Astronomy, 2008-04-20)
      We use projected number density profiles of galaxy groups to investigate the relationship between galaxy group structure and dark matter structure within halos. We primarily study a specific model of how galaxies populate ...
