A probable Milli-Parsec Supermassive Binary Black Hole in the Nearest Quasar Mrk 231
Chang-Shuo Yan, Youjun Lu, Xinyu Dai +1
Supermassive binary black holes (BBHs) are unavoidable products of galaxy mergers and are expected to exist in the cores of many quasars. Great effort has been made during the past…
Algorithms And Programs For Strong Gravitational Lensing In Kerr Space-time Including Polarization
Bin Chen, Ronald Kantowski, Xinyu Dai +2
Active galactic nuclei (AGNs) and quasars are important astrophysical objects to understand. Recently, microlensing observations have constrained the size of the quasar X-ray emiss…
The Swift AGN and Cluster Survey. II. Cluster Confirmation with SDSS Data
Rhiannon D. Griffin, Xinyu Dai, Christopher S. Kochanek +1
We study 203 (of 442) Swift AGN and Cluster Survey extended X-ray sources located in the SDSS DR8 footprint to search for galaxy over-densities in three dimensional space using SDS…
The SWIFT AGN and Cluster Survey I: Number Counts of AGN and Galaxy Clusters
Xinyu Dai, Rhiannon D. Griffin, Christopher S. Kochanek +2
The Swift AGN and Cluster Survey (SACS) uses 125 deg^2 of Swift XRT serendipitous fields with variable depths surrounding gamma-ray bursts to provide a medium depth (4e-15 erg/s/cm…
A Consistent Picture Emerges: A Compact X-ray Continuum Emission Region in the Gravitationally Lensed Quasar SDSS J0924+0219
Chelsea L. MacLeod, Christopher Morgan, A. Mosquera +7
We analyze the optical, UV, and X-ray microlensing variability of the lensed quasar SDSS J0924+0219 using six epochs of Chandra data in two energy bands (spanning 0.4-8.0 keV, or 1…
