Are ring galaxies the ancestors of giant low surface brightness galaxies?
M. Mapelli, B. Moore, E. Ripamonti +4
Giant low surface brightness galaxies (GLSBs) have flat discs extending up to ~100 kpc. Their formation is a puzzle for cosmological simulations in the cold dark matter scenario. W…
Comments on ``Are Swift Gamma-Ray Bursts consistent with the Ghirlanda relation?", by Campana et al.(astro--ph/0703676)
G. Ghirlanda, L. Nava, G. Ghisellini +1
In their recent paper, Campana et al. (2007) found that 5 bursts, among those detected by Swift, are outliers with respect to the E_peak-E_gamma ("Ghirlanda") correlation. We inste…
Radioquiet isolated neutron stars: old and young, nearby and far away, dim and very dim
S. B. Popov, A. Treves, R. Turolla
We briefly discuss the evolutionary path and observational appearance of isolated neutron stars (INSs) focusing on radioquiet objects. There are many reasons to believe that these…
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…
