(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 ...

(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 ...
-
(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 ...

(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 ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)Rotation period distributions for older open clusters are difficult to obtain because of the general scarcity of clusters with ages greater than 200 Myr, as well as the challenge of measuring rotation periods for less ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2016-05-18)Using data from the Kilodegree Extremely Little Telescope (KELT) project, we performed a survey of 2028 known M Dwarf stars in the KELT footprint for M-M Dwarf eclipsing binaries (EBs). After searching 2028 Mdwarf ...

(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)We report time-series CCD I-band photometry for the pre-main-sequence cluster NGC 6530, located within the Lagoon Nebula. The data were obtained with the 4Kx4K imager on the SMARTS 1.0m telescope at CTIO on 36 nights over ...
-
(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)We demonstrate the acceleration obtained from using GPU/CPU hybrid clusters and supercomputers for N-body simulations of gravity based in part on the author's new code development. Validation tests are shown for ...

(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-27)Blazars AP Librae and 3c279 are analyzed for microvariability using a technique known as structure function analysis. AP Librae was observed in April of 2005 and 3c279 was observed in April of 2007. The data for AP Librae ...
