Hidden activity in high-redshift spheroidal galaxies from mid-infrared and X-ray observations in the GOODS-North field
G. Rodighiero, C. Gruppioni, F. Civano +6
We exploit very deep mid-IR (MIR) and X-ray observations by Spitzer and Chandra in the GOODS North to identify signs of hidden (either starburst or AGN) activity in spheroidal gala…
Revisiting the Infrared Spectra of Active Galactic Nuclei with a New Torus Emission Model
J. Fritz, A. Franceschini, E. Hatziminaoglou
We describe improved modelling of the emission by dust in a toroidal--like structure heated by a central illuminating source within Active Galactic Nuclei (AGN). We chose a simple…
Photometric Estimates of Stellar Masses in High-Redshift Galaxies
Stefano Berta, Jacopo Fritz, Alberto Franceschini +2
We present a new tool for the photometric estimate of stellar masses in distant galaxies. The observed SEDs are fitted by combining single stellar populations, with different SFRs…
Spatially-resolved spectrophotometric analysis and modelling of the Superantennae
Stefano Berta, Jacopo Fritz, Alberto Franceschini +2
We have performed spatially-resolved spectroscopy of the double-nucleated Ultra-Luminous Infrared Galaxy IRAS 19254-7245, ``the Superantennae'', along the line connecting the two n…
Spectro-Polarimetric search for hidden AGNs in four southern Ultraluminous Infrared Galaxies
C. Pernechele, S. Berta, A. Marconi +5
We report on a spectro-polarimetric analysis of four southern Ultra-Luminous Infrared Galaxies (ULIRGs), aimed at constraining the presence of hidden broad AGN lines. For IRAS 1925…
