Given its general importance for studies of star formation at all redshifts, the issue of the heating mechanism for the warm/cool dust in luminous AGN is one of the key problems in extragalactic astrophysics. We propose to address this issue by using the unique high sensitivity capability of the Spitzer to make a mid- to far-IR (MFIR) photometric

We describe TRILEGAL, a new populations synthesis code for simulating the stellar photometry of any Galaxy field. The code attempts to improve upon several technical aspects of star count models, by: dealing with very complete input libraries of evolutionary tracks; using a stellar spectral library to simulate the photometry in virtually any broad

In this paper we present new results obtained from our spectroscopic survey of near-Earth objects (called SINEO). We show a set of 36 visible and near-infrared spectra, recorded with the 3.5-m Italian Telescopio Nazionale Galileo at La Palma (Canary Island). We discuss their taxonomic classification (resulting in 25 objects belonging to the S

We describe the source subtraction strategy and observations for the extended Very Small Array (VSA), a cosmic microwave background interferometer operating at 33 GHz. A total of 453 sources were monitored at 33 GHz using a dedicated source subtraction baseline. 131 sources brighter than 20 mJy were directly subtracted from the VSA visibility data

Based on the most widely accepted model for structure formation in the Universe, the massive galaxies we see today are the result of the merging of smaller structures. Looking far enough, and therefore far back in time, one should then be able to see galaxies getting smaller and smaller. To explore this issue we focus on quasars host galaxies and
