X-ray luminosity functions of different morphological and X-ray type AGN populations

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 for different optical morphologies and X-ray...

FIR measurements of Ly-$\alpha$ emitters at z$\lesssim$1.0: dust attenuation from PACS-\emph{Herschel}

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...

Evolution of the Fundamental Plane of 0.2&#60;z&#60;1.2 Early-type galaxies in the EGS

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...
