A Normal Abundance of Faint Satellites in the Fossil Group NGC 6482
S. Lieder, S. Mieske, R. Sánchez-Janssen +3
Fossil groups are considered the end product in a galaxy group's evolution -- a massive central galaxy that dominates the luminosity budget of the group, as the outcome of efficien…

R. Bordoloi, S. J. Lilly, E. Hardmeier +44
We present an analysis of cool outflowing gas around galaxies, traced by MgII absorption lines in the co-added spectra of a sample of 486 zCOSMOS galaxies at 1 < z < 1.5. These gal…
zCOSMOS 20k: Satellite galaxies are the main drivers of environmental effects in the galaxy population at least to z~0.7
K. Kovac, S. J. Lilly, C. Knobel +41
We explore the role of environment in the evolution of galaxies over 0.1<z<0.7 using the final zCOSMOS-bright data set. Using the red fraction of galaxies as a proxy for the quench…
The lack of star formation gradients in galaxy groups up to z~1.6
Felicia Ziparo, Paola Popesso, Andrea Biviano +28
In the local Universe, galaxy properties show a strong dependence on environment. In cluster cores, early type galaxies dominate, whereas star-forming galaxies are more and more co…
Larger sizes of massive quiescent early-type galaxies in clusters than in the field at 0.8 < z < 1.5
L. Delaye, M. Huertas-Company, S. Mei +13
[abridged] The mass-size relation of early-type galaxies (ETGs) has been largely studied in the last years to probe the mass assembly of the most massive objects in the Universe. I…
Obscured AGN at z~1 from the zCOSMOS-Bright Survey I. Selection and Optical Properties of a [Ne v]-selected sample
M. Mignoli, C. Vignali, R. Gilli +46
A sample of 94 narrow line AGN with 0.65<z<1.20 has been selected from the 20k-Bright zCOSMOS galaxy sample by detection of the high-ionization [NeV]3426 line. Taking advantage of…
Dust-obscured star-formation in the outskirts of XMMU J2235.3-2557, a massive galaxy cluster at z=1.4
J. S. Santos, B. Altieri, P. Popesso +17
Star-formation in the galaxy populations of local massive clusters is reduced with respect to field galaxies, and tends to be suppressed in the core region. Indications of a revers…
Spot the difference. Impact of different selection criteria on observed properties of passive galaxies in zCOSMOS 20-k sample
M. Moresco, L. Pozzetti, A. Cimatti +50
We present the analysis of photometric, spectroscopic, and morphological properties for differently selected samples of passive galaxies up to z=1 extracted from the zCOSMOS-20k sp…

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…
