The Colors of Central and Satellite Galaxies in zCOSMOS out to z ~ 0.8 and Implications for Quenching

C. Knobel, S. J. Lilly, K. Kovac +47

We examine the red fraction of central and satellite galaxies in the large zCOSMOS group catalog out to z ~ 0.8 correcting for both the incompleteness in stellar mass and for the l…

Modeling the distribution of Mg II absorbers around galaxies using Background Galaxies & Quasars

R. Bordoloi, S. J. Lilly, G. G. Kacprzak +1

We present joint constraints on the distribution of MgII absorption around galaxies, by combining the MgII absorption seen in stacked background galaxy spectra and the distribution…

Proto-groups at 1.8<z<3 in the zCOSMOS-deep sample

C. Diener, S. J. Lilly, C. Knobel +48

We identify 42 candidate groups lying between 1.8<z<3.0 from a sample of 3502 galaxies with spectroscopic redshifts in the zCOSMOS-deep redshift survey within the same redshift int…

A group-galaxy cross-correlation function analysis in zCOSMOS

C. Knobel, S. J. Lilly, C. M. Carollo +46

We present a group-galaxy cross-correlation analysis using a group catalog produced from the 16,500 spectra from the optical zCOSMOS galaxy survey. Our aim is to perform a consiste…

The zCOSMOS 20k Group Catalog

C. Knobel, S. J. Lilly, A. Iovino +48

We present an optical group catalog between 0.1 < z < 1 based on 16,500 high-quality spectroscopic redshifts in the completed zCOSMOS-bright survey. The catalog published herein co…

Environmental effects in the interaction and merging of galaxies in zCOSMOS survey

P. Kampczyk, S. J. Lilly, the zCOSMOS Collaboration

The zCOSMOS-bright 10k spectroscopic sample reveals a strong environmental dependence of close kinematic galaxy pair fractions in the redshift range 0.2 < z < 1. The fraction of cl…

The COSMOS Density Field: A Reconstruction Using Both Weak Lensing and Galaxy Distributions

A. Amara, S. Lilly, K. Kovac +49

The COSMOS field has been the subject of a wide range of observations, with a number of studies focusing on reconstructing the 3D dark matter density field. Typically, these studie…

The dominant role of mergers in the size evolution of massive early-type galaxies since z ~ 1

C. López-Sanjuan, O. Le Fèvre, O. Ilbert +60

In this paper we measure the merger fraction and rate, both minor and major, of massive early-type galaxies (M_star >= 10^11 M_Sun) in the COSMOS field, and study their role in mas…

A journey from the outskirts to the cores of groups I: Color- and mass-segregation in 20K-zCOSMOS groups

V. Presotto, A. Iovino, M. Scodeggio +49

Using the group catalog obtained from zCOSMOS spectroscopic data and the complementary photometric data from the COSMOS survey, we explore segregation effects occurring in groups o…

Photo-z Performance for Precision Cosmology II : Empirical Verification

R. Bordoloi, S. J. Lilly, A. Amara +8

The success of future large scale weak lensing surveys will critically depend on the accurate estimation of photometric redshifts of very large samples of galaxies. This in turn de…

Improved constraints on the expansion rate of the Universe up to z~1.1 from the spectroscopic evolution of cosmic chronometers

M. Moresco, A. Cimatti, Raul Jimenez +65

We present new improved constraints on the Hubble parameter H(z) in the redshift range 0.15 < z < 1.1, obtained from the differential spectroscopic evolution of early-type galaxies…
