A weak gravitational lensing recalibration of the scaling relations linking the gas properties of dark halos to their mass
Wenting Wang, Simon White, Rachel Mandelbaum +3
We use weak gravitational lensing to measure mean mass profiles around Locally Brightest Galaxies (LBGs). These are selected from the SDSS/DR7 spectroscopic and photometric catalog…
Unifying X-ray Scaling Relations from Galaxies to Clusters
Michael E. Anderson, Massimo Gaspari, Simon D. M. White +2
We examine a sample of "locally brightest galaxies" selected from the Sloan Digital Sky Survey to be central galaxies within their dark matter halos. These were prev…
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…
XMM-Newton Detects a Hot Gaseous Halo in the Fastest Rotating Spiral Galaxy UGC 12591
Xinyu Dai, Michael E. Anderson, Joel N. Bregman +1
We present our XMM-Newton observation of the fastest rotating spiral galaxy UGC 12591. We detect hot gas halo emission out to 110 kpc from the galaxy center, and constrain the halo…
Detection of a Hot Gaseous Halo Around the Giant Spiral Galaxy NGC 1961
Michael E. Anderson, Joel N. Bregman
Hot gaseous halos are predicted around all large galaxies and are critically important for our understanding of galaxy formation, but they have never been detected at distances bey…
Metal Production in Galaxy Clusters: The Non-Galactic Component
Joel N. Bregman, Michael E. Anderson, Xinyu Dai
The metallicity in galaxy clusters is expected to originate from the stars in galaxies, with a population dominated by high mass stars likely being the most important stellar compo…
Do Hot Haloes Around Galaxies Contain the Missing Baryons?
Michael E. Anderson, Joel N. Bregman
Galaxies are missing most of their baryons, and many models predict these baryons lie in a hot halo around galaxies. We establish observationally motivated constraints on the mass…
Redshift Evolution in the Iron Abundance of the Intracluster Medium
Michael E. Anderson, Joel N. Bregman, Suzanne C. Butler +1
Clusters of galaxies provide a closed box within which one can determine the chemical evolution of the gaseous baryons with cosmic time. We studied this metallicity evolution in th…
