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…

The supernova rate per unit mass

F. Mannucci, M. Della Valle, N. Panagia +5

We compute the rate of supernovae (SNe) of different types along the Hubble sequence normalized to the near-infrared luminosity and to the stellar mass of the parent galaxies. This…

A supernova origin for dust in a high-redshift quasar

R. Maiolino, R. Schneider, E. Oliva +5

Interstellar dust plays a crucial role in the evolution of the Universe by assisting the formation of molecules, by triggering the formation of the first low-mass stars, and by abs…

Local Supermassive Black Holes and Relics of Active Galactic Nuclei

A. Marconi, G. Risaliti, R. Gilli +3

We summarize a study where we test the hypothesis that local black holes (BH) are relics of AGN activity. We compare the mass function of BHs in the local universe with that expect…

Nuclear star formation in the quasar PG1126-041 from adaptive optics assisted spectroscopy

G. Cresci, R. Maiolino, A. Marconi +2

We present adaptive optics assisted spectroscopy of three quasars obtained with NACO at VLT. The high angular resolution achieved with the adaptive optics (~0.08"), joined to the d…

24 micron Properties of X-ray Selected AGN

J. R. Rigby, G. H. Rieke, R. Maiolino +13

We examine the 24 micron to X-ray color of 157 X-ray--selected AGN as a function of X-ray obscuration and optical classification in the Chandra Deep Field South. The sample consist…
