Two populations of progenitors for type Ia SNe?
F. Mannucci, M. Della Valle, N. Panagia
We use recent observations of type Ia Supernova (SN Ia) rates to derive, on robust empirical grounds, the distribution of the delay time (DTD) between the formation of the progenit…
Constraining the thermal history of the Warm-Hot Intergalactic Medium
L. Zappacosta, R. Maiolino, A. Finoguenov +3
We have identified a large-scale structure traced by galaxies at z=0.8, within the Lockman Hole, by means of multi-object spectroscopic observations. By using deep XMM images we ha…
Observational tests of the evolution of spheroidal galaxies
Laura Silva, Gianfranco De Zotti, Gian Luigi Granato +2
Granato et al (2004) have elaborated a physically grounded model exploiting the mutual feedback between star-forming spheroidal galaxies and the active nuclei growing in their core…
Observational tests of the evolution of spheroidal galaxies and predictions for SIRTF/Spitzer cosmological surveys
Laura Silva, Gianfranco De Zotti, Gian Luigi Granato +2
Granato et al(2004) have elaborated a physically grounded model exploiting the mutual feedback between star-forming spheroidal galaxies and the active nuclei growing in their cores…
Connecting the cosmic infrared background to the X-ray background
Laura Silva, Roberto Maiolino, Gian Luigi Granato
We estimate the contribution of AGNs and of their host galaxies to the infrared background. We use the luminosity function and evolution of AGNs recently determined by the hard X-r…
