Extended Hot Halos Around Isolated Galaxies Observed in the ROSAT All-Sky Survey
Michael E. Anderson, Joel N. Bregman, Xinyu Dai
We place general constraints on the luminosity and mass of hot X-ray emitting gas residing in extended "hot halos" around nearby massive galaxies. We examine stacked images of 2165…
Effects of Kerr Strong Gravity on Quasar X-ray Microlensing
Bin Chen, Xinyu Dai, Eddie Baron +1
Recent quasar microlensing observations have constrained the sizes of X-ray emission regions to be within about 10 gravitational radii of the central supermassive black hole. There…
Inclination-Dependent AGN Flux Profiles From Strong Lensing of the Kerr Space-Time
Bin Chen, Xinyu Dai, Eddie Baron
Recent quasar microlensing observations have constrained the X-ray emission sizes of quasars to be about 10 gravitational radii, one order of magnitude smaller than the optical emi…
The Hidden Fortress: Structure and substructure of the complex strong lensing cluster SDSS J1029+2623
Masamune Oguri, Tim Schrabback, Eric Jullo +8
We present Hubble Space Telescope (HST) ACS and WFC3 observations of SDSS J1029+2623, a three-image quasar lens system produced by a foreground cluster at z=0.584. Our strong lensi…
On Absorption by Circumstellar Dust, With the Progenitor of SN2012aw as a Case Study
C. S. Kochanek, R. Khan, X. Dai
We use the progenitor of SN2012aw to illustrate the consequences of modeling circumstellar dust using Galactic (interstellar) extinction laws that (1) ignore dust emission in the n…
A Bayesian Monte-Carlo Analysis of the M-sigma Relation
Leah Morabito, Xinyu Dai
We present an analysis of selection biases in the M-sigma relation using Monte- Carlo simulations including the sphere of influence resolution selection bias and a selection bias i…
