The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: the low redshift sample
John K. Parejko, Tomomi Sunayama, Nikhil Padmanabhan +36
We report on the small scale (0.5<r<40h^-1 Mpc) clustering of 78895 massive (M*~10^11.3M_sun) galaxies at 0.2<z<0.4 from the first two years of data from the Baryon Oscillation Spe…
Cosmological Constraints from a Combination of Galaxy Clustering and Lensing -- III. Application to SDSS Data
Marcello Cacciato, Frank C. van den Bosch, Surhud More +2
We simultaneously constrain cosmology and galaxy bias using measurements of galaxy abundances, galaxy clustering and galaxy-galaxy lensing taken from the Sloan Digital Sky Survey.…
Cosmological Constraints from a Combination of Galaxy Clustering & Lensing -- II. Fisher Matrix Analysis
Surhud More, Frank van den Bosch, Marcello Cacciato +3
We quantify the accuracy with which the cosmological parameters characterizing the energy density of matter (Ω_m), the amplitude of the power spectrum of matter fluctuations (σ_8),…
Cosmological Constraints from a Combination of Galaxy Clustering and Lensing -- I. Theoretical Framework
Frank van den Bosch, Surhud More, Marcello Cacciato +2
We present a new method that simultaneously solves for cosmology and galaxy bias on non-linear scales. The method uses the halo model to analytically describe the (non-linear) matt…
The Gas-Phase Metallicity of Central and Satellite Galaxies in the SDSS
Anna Pasquali, Anna Gallazzi, Frank C. van den Bosch
We exploit the SDSS galaxy groups catalogue of Yang et al. to study how the gas-phase metallicities of star-forming galaxies depend on environment. We find that satellite and centr…
Galaxy evolution in groups and clusters: satellite star formation histories and quenching timescales in a hierarchical Universe
Andrew R. Wetzel, Jeremy L. Tinker, Charlie Conroy +1
Satellite galaxies in groups and clusters are more likely to have low star formation rates (SFR) and lie on the red-sequence than central (field) galaxies. Using galaxy group/clust…
Internal kinematics of groups of galaxies in the Sloan Digital Sky Survey data release 7
Cheng Li, Y. P. Jing, Shude Mao +5
We present measurements of the velocity dispersion profile (VDP) for galaxy groups in the final data release of the Sloan Digital Sky Survey (SDSS). For groups of given mass we est…
The Galaxy-Dark Matter Connection: A Cosmological Perspective
Surhud More, Frank van den Bosch, Marcello Cacciato +3
We present a method that uses observations of galaxies to simultaneously constrain cosmological parameters and the galaxy-dark matter connection (aka halo occupation statistics). T…
On Combining Galaxy Clustering and Weak Lensing to Unveil Galaxy Biasing via the Halo Model
Marcello Cacciato, Ofer Lahav, Frank C. van den Bosch +2
We formulate the concept of non-linear and stochastic galaxy biasing in the framework of halo occupation statistics. Using two-point statistics in projection, we define the galaxy…
