Environmental effects in the interaction and merging of galaxies in zCOSMOS
P. Kampczyk, S. J. Lilly, L. de Ravel +56
(Abridged) We analyze the environments and galactic properties (morphologies and star-formation histories) of a sample of 153 close kinematic pairs in the redshift range 0.2 < z <…
The impact of galaxy interactions on AGN activity in zCOSMOS
J. D. Silverman, P. Kampczyk, K. Jahnke +52
Close encounters between galaxies are expected to be a viable mechanism, as predicted by numerical simulations, by which accretion onto supermassive black holes can be initiated. T…
Early-type galaxies at z~1.3. IV. Scaling relations in different environments
A. Raichoor, S. Mei, S. A. Stanford +15
We present the Kormendy and mass-size relations for early-type galaxies (ETGs) as a function of environment at z~1.3. Our sample includes 76 visually classified ETGs with masses 10…
On the occupation of X-ray selected galaxy groups by radio AGN since z=1.3
V. Smolcic, A. Finoguenov, G. Zamorani +4
Previous clustering analysis of low-power radio AGN has indicated that they preferentially live in massive groups. The X-ray surveys of the COSMOS field have achieved a sensitivity…
The evolution of quiescent galaxies at high redshift (z > 1.4)
H. Domínguez Sánchez, F. Pozzi, C. Gruppioni +45
We have studied the evolution of high redshift quiescent galaxies over an effective area of ~1.7 deg^2 in the COSMOS field. Galaxies have been divided according to their star-forma…
The radial and azimuthal profiles of Mg II absorption around 0.5 < z < 0.9 zCOSMOS galaxies of different colors, masses and environments
R. Bordoloi, S. J. Lilly, C. Knobel +50
We map the radial and azimuthal distribution of Mg II gas within 200 kpc (physical) of 4000 galaxies at redshifts 0.5 < z < 0.9 using co-added spectra of more than 5000 background…
Black hole accretion and host galaxies of obscured quasars in XMM-COSMOS
V. Mainieri, A. Bongiorno, A. Merloni +61
We explore the connection between black hole growth at the center of obscured quasars selected from the XMM-COSMOS survey and the physical properties of their host galaxies. We stu…
Early-Type galaxies at z ~ 1.3. III. On the dependence of Formation Epochs and Star Formation Histories on Stellar Mass and Environment
Alessandro Rettura, S. Mei, S. A. Stanford +20
We study the environmental dependence of stellar population properties at z ~ 1.3. We derive galaxy properties (stellar masses, ages and star formation histories) for samples of ma…
Early-type galaxies at z~1.3. II. Masses and ages of early-type galaxies in different environments and their dependence on stellar population model assumptions
A. Raichoor, S. Mei, F. Nakata +14
We have derived masses and ages for 79 early-type galaxies (ETGs) in different environments at z~1.3 in the Lynx supercluster and in the GOODS/CDF-S field using multiwavelength (0.…
