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.
