J/A+A/526/A72    Early-type galaxies in the EGS       (Fernandez Lorenzo+, 2011)

Evolution of the fundamental plane of 0.2<z<1.2 early-type galaxies in the EGS. Fernandez Lorenzo M., Cepa J., Bongiovanni A., Perez Garcia A., Ederoclite A., Lara-Lopez M.A. Povic M., Sanchez-Portal M. <Astron. Astrophys. 526, A72 (2011)> =2011A&A...526A..72F
ADC_Keywords: Galaxies, photometry ; Morphology Keywords: galaxies: evolution - galaxies: fundamental parameters - galaxies: elliptical and lenticular, cD - galaxies: kinematics and dynamics Abstract: The fundamental plane links the structural properties of early-type galaxies such as its surface brightness and effective radius with its dynamics. The study of the fundamental plane evolution therefore has important implications for models of galaxy formation and evolution. This work aims to identify signs of evolution of early-type galaxies through the study of parameter correlations such as the fundamental plane, the Kormendy, and the Faber-Jackson relations, using a sample of 135 field galaxies extracted from the Extended Groth Strip in the redshift range 0.2<z<1.2. Description: Physical parameters for 135 early-type galaxies in the Extended Groth Strip (EGS). For each galaxy equatorial coordinates, total magnitudes in B and g-bands, redshift, velocity dispersion, effective radius, surface brightness, stellar mass, Sersic index, type (elliptical or lenticular) and signal-to-noise of the spectrum are given.
