Luminosity functions are one of the most important observational clues
when studying galaxy evolution over cosmic time. In this paper we
present the X-ray luminosity functions for X-ray detected AGN in the SXDS and GWS fields. The limiting fluxes of our samples are 9.0
×10<SUP>-15</SUP> and 4.8 ×10<SUP>-16</SUP> erg
cm<SUP>-2</SUP> s<SUP>-1</SUP> in the 0.5-7.0 keV band in the two
fields, respectively. We carried out analysis in three X-ray bands and
in two redshift intervals up to z&leq;1.4. Moreover, we derive the
luminosity functions…
One remaining open question regarding the physical properties of
Ly$\alpha$ emitters (LAEs) is their dust content and its evolution with
redshift. The variety of results is large and with those reported by now
is difficult to establish clear relations between dust, other
fundamental parameters of galaxies (star-formation rate, metallicity or
age) and redshift. In this Letter, we report \emph{Herschel} PACS-100$\mu$m, PACS-160$\mu$m and \emph{Spitzer} MIPS-24$\mu$m
detections of a sample of spectroscopically GALEX-selected LAEs at
z$\sim$0.3 and $\sim$1.0. Five out of ten and one out of two…
The Fundamental Plane relates the structural properties of early-type
galaxies such as its surface brightness and effective radius with its
dynamics. The study of its evolution has therefore 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 using a sample of 135 field galaxies
extracted from the Extended Groth Strip in the redshift range
0.2<z<1.2. Using DEEP2 data, we calculate the internal velocity
dispersions by extracting the stellar kinematics from…
