Measuring the X-ray luminosities of SDSS DR7 clusters from RASS
Lei Wang, Xiaohu Yang, Shiyin Shen +8
We use ROSAT All Sky Survey (RASS) broadband X-ray images and the optical clusters identified from SDSS DR7 to estimate the X-ray luminosities around candidate cluste…
First Galaxy-Galaxy Lensing Measurement of Satellite Halo Mass in the CFHT Stripe-82 Survey
Ran Li, Huanyuan Shan, HouJun Mo +7
We select satellite galaxies from the galaxy group catalog constructed with the SDSS spectroscopic galaxies and measure the tangential shear around these galaxies with source catal…
Generating Merger Trees for Dark Matter Haloes: A Comparison of Methods
Fangzhou Jiang, Frank C. van den Bosch
Halo merger trees describe the hierarchical mass assembly of dark matter haloes, and are the backbone for modeling galaxy formation and evolution. Merger trees constructed using Mo…
Galaxy Assembly Bias: A Significant Source of Systematic Error in the Galaxy-Halo Relationship
Andrew R. Zentner, Andrew P. Hearin, Frank C. van den Bosch
It is common practice for methods that use galaxy clustering to constrain the galaxy-halo relationship, such as the halo occupation distribution (HOD) and/or conditional luminosity…
Alignments of galaxies within cosmic filaments from SDSS DR7
Youcai Zhang, Xiaohu Yang, Huiyuan Wang +3
Using a sample of galaxy groups selected from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we examine the alignment between the orientation of galaxies and their surroun…
A new population of recently quenched elliptical galaxies in the SDSS
Daniel H. McIntosh, Cory Wagner, Andrew Cooper +8
We use the Sloan Digital Sky Survey to investigate the properties of massive elliptical galaxies in the local Universe (z\leq0.08) that have unusually blue optical colors. Through…
The statistical nature of the brightest group galaxies
Shiyin Shen, Xiaohu Yang, Houjun Mo +2
We examine the statistical properties of the brightest group galaxies (BGGs) using a complete spectroscopic sample of groups/clusters of galaxies selected from the Data Release 7 o…
An Empirical Model for the Star Formation History in Dark Matter Halos
Zhankui Lu, Houjun Mo, Yu Lu +4
We develop an empirical approach to infer the star formation rate in dark matter halos from the galaxy stellar mass function (SMF) at different redshifts and the local cluster gala…
Galaxy evolution near groups and clusters: ejected satellites and the spatial extent of environmental quenching
Andrew R. Wetzel, Jeremy L. Tinker, Charlie Conroy +1
Galaxies that are several virial radii beyond groups/clusters show preferentially quiescent star formation rates. Using a galaxy group/cluster catalog from the Sloan Digital Sky Su…
Disk Assembly and the M_BH-sigma Relation of Supermassive Black Holes
Victor P. Debattista, Stelios Kazantzidis, Frank C. van den Bosch
Recent Hubble Space Telescope (HST) observations have revealed that a majority of active galactic nuclei (AGN) at z ~ 1-3 are resident in isolated disk galaxies, contrary to the us…
Reconstructing the Initial Density Field of the Local Universe: Method and Test with Mock Catalogs
Huiyuan Wang, H. J. Mo, Xiaohu Yang +1
Our research objective in this paper is to reconstruct an initial linear density field, which follows the multivariate Gaussian distribution with variances given by the linear powe…
