The cosmic infrared background (CIRB) and the role of the "local environment of galaxies" in the origin of present-day stars
David Elbaz, Delphine Marcillac, Emmanuel Moy
A combination of evidence is presented suggesting that the majority of the stars in today's galaxies were born during a luminous infrared phase (LIRP) triggered by the local enviro…
The radio galaxy K-z relation: the 10^12 Msol mass limit; masses of galaxies from the L_K luminosity, up to z >4
B. Rocca-Volmerange, D. Le Borgne, C. De Breuck +2
The narrow K-z relation of powerful radio galaxies in the Hubble K diagram is often attributed to the stellar populations of massive elliptical galaxies. Extended over a large rang…
Infrared spectroscopy of faint 15 micron sources in the Hubble Deep Field South: first hints at the properties of the sources of the IR background
A. Franceschini, S. Berta, D. Rigopoulou +8
We present a spectroscopic analysis of 21 galaxies with z=0.2-1.5 drawn from a 25 sq. arcmin ultra-deep 15 micron ISOCAM survey centered in the HDFS. VLT/ISAAC spectra are reported…
H-band observations of the Chandra Deep Field South
E. Moy, P. Barmby, D. Rigopoulou +3
We report preliminary results of our H-band survey of the Chandra Deep Field South (CDFS). The observations were made using SofI on the NTT, and cover 0.027 square degrees with a 5…
