MApping the Most Massive Overdensities Through Hydrogen (MAMMOTH) I: Methodology
Zheng Cai, Xiaohui Fan, Sebastien Peirani +8
Modern cosmology predicts that a galaxy overdensity is associated to a large reservoir of the intergalactic gas, which can be traced by the Ly forest absorption. We have underta…
The optical luminosity function from a sample of galaxies in bootes
Richard A. Beare, Michael J. I. Brown, Kevin A. Pimbblet +2
Using a sample of ~410 000 galaxies to depth I_AB = 24 over 8.26 deg^2 in the Bootes field (~10 times larger than z~1 luminosity function studies in the prior literature), we have…
An ultra-luminous quasar at z=5.363 with a ten billion solar mass black hole and a Metal-Rich DLA at z~5
Feige Wang, Xue-Bing Wu, Xiaohui Fan +11
We report the discovery of an ultra-luminous quasar J030642.51+185315.8 (hereafter J0306+1853) at redshift 5.363, which hosts a super-massive black hole (SMBH) with $M_{BH} = (1.07…
Preprocessing Among the Infalling Galaxy Population of EDisCS Clusters
Dennis W. Just, Matthew Kirby, Dennis Zaritsky +15
We present results from a low-resolution spectroscopic survey for 21 galaxy clusters at selected from the ESO Distant Cluster Survey. We measured spectra using the…
Discovery of Eight z ~ 6 Quasars in the Sloan Digital Sky Survey Overlap Regions
Linhua Jiang, Ian D. McGreer, Xiaohui Fan +5
We present the discovery of eight quasars at z~6 identified in the Sloan Digital Sky Survey (SDSS) overlap regions. Individual SDSS imaging runs have some overlap with each other,…
An ultra-luminous quasar with a twelve-billion-solar-mass black hole at redshift 6.30
Xue-Bing Wu, Feige Wang, Xiaohui Fan +10
So far, roughly 40 quasars with redshifts greater than z=6 have been discovered. Each quasar contains a black hole with a mass of about one billion solar masses (). T…
