zCOSMOS: A Large VLT/VIMOS redshift survey covering 0 < z < 3 in the COSMOS field
S. J. Lilly, O. Le Fevre, A. Renzini +42
zCOSMOS is a large redshift survey that is being undertaken in the COSMOS field using 600 hours of observation with the VIMOS spectrograph on the 8-m VLT. The survey is designed to…
COSMOS morphological classification with ZEST (the Zurich Estimator of Structural Types) and the evolution since z=1 of the Luminosity Function of early-, disk-, and irregular galaxies
C. Scarlata, C. M. Carollo, S. J. Lilly +26
(ABRIDGED) Motivated by the desire to reliably and automatically classify structure of thousands of COSMOS galaxies, we present ZEST, the Zurich Estimator of Structural Types. To c…
Simulating the COSMOS: The fraction of merging galaxies at high redshift
P. Kampczyk, S. J. Lilly, C. M. Carollo +6
Simulations of nearby (0.015 < z < 0.025) SDSS galaxies have been used to reproduce as accurately as possible the appearance that they would have on COSMOS ACS images if they had b…
Old and young bulges in late-type disk galaxies
C. M. Carollo, C. Scarlata, M. Stiavelli +2
ABRIDGED: We use HSTACS and NICMOS imaging to study the structure and colors of a sample of nine late-type spirals. We find: (1) A correlation between bulge and disks scale-lengths…
The Zurich Extragalactic Bayesian Redshift Analyzer (ZEBRA) and its first application: COSMOS
R. Feldmann, C. M. Carollo, C. Porciani +21
We present ZEBRA, the Zurich Extragalactic Bayesian Redshift Analyzer. The current version of ZEBRA combines and extends several of the classical approaches to produce accurate pho…
The evolution of the number density of large disk galaxies in COSMOS
M. T. Sargent, C. M. Carollo, S. J. Lilly +17
We study a sample of approximately 16,500 galaxies with I_AB <= 22.5 in the COSMOS field. Structural information on the galaxies is derived by fitting single Sersic models to their…
