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…
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…
The cosmic evolution of oxygen and nitrogen abundances in star-forming galaxies over the past 10 Gyrs
E. Perez-Montero, T. Contini, F. Lamareille +35
The chemical evolution of galaxies on a cosmological timescale is still a matter of debate despite the increasing number of available data provided by spectroscopic surveys of star…
Occupation of X-ray selected galaxy groups by X-ray AGN
V. Allevato, A. Finoguenov, G. Hasinger +12
We present the first direct measurement of the mean Halo Occupation Distribution (HOD) of X-ray selected AGN in the COSMOS field at z < 1, based on the association of 41 XMM and 17…
Deep observations of CO line emission from star-forming galaxies in a cluster candidate at z=1.5
M. Aravena, C. L. Carilli, M. Salvato +20
We report results from a deep Jansky Very Large Array (JVLA) search for CO 1-0 line emission from galaxies in a candidate galaxy cluster at z~1.55 in the COSMOS field. We target 4…
Stellar velocity dispersions and emission line properties of SDSS-III/BOSS galaxies
D. Thomas, O. Steele, C. Maraston +24
We perform a spectroscopic analysis of 492,450 galaxy spectra from the first two years of observations of the Sloan Digital Sky Survey-III/Baryonic Oscillation Spectroscopic Survey…
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 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…
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…
