Extragalactic Background Light, MACHOs, and the Cosmic Stellar Baryon Budget
Piero Madau, Francesco Haardt, Lucia Pozzetti
The optical/far-IR extragalactic background light (EBL) from both resolved and unresolved extragalactic sources is an indicator of the total luminosity of cosmic structures, as the…
A Self-Consistent Test of Comptonisation Models Using Bepposax Observations of Seyfert Galaxies
P. O. Petrucci, F. Haardt, L. Maraschi +6
We test accurate models of Comptonisation spectra over BeppoSAX observations of Seyfert galaxies focusing on the long look at NGC 5548. The hot plasma temperature derived with thes…
BeppoSAX observations of Mrk 509 and MCG+8-11-11
G. C. Perola, G. Matt, F. Fiore +7
BeppoSAX observations of the Seyfert galaxies Mrk 509 and MCG+8-11-11 are presented. Earlier evidence of a soft excess in Mrk 509 is confirmed. This excess is found to be better re…
