The isolated neutron star candidate 2XMM J104608.7-594306
A. M. Pires, C. Motch, R. Turolla +2
Over the last decade, X-ray observations unveiled the existence of several classes of isolated neutron stars (INSs) which are radio-quiet or exhibit radio emission with properties…
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…
Peak energy of the prompt emission of long Gamma Ray Bursts vs their fluence and peak flux
Lara Nava, Giancarlo Ghirlanda, Gabriele Ghisellini +1
The spectral-energy and (luminosity) correlations in long GRBs are being hotly debated to establish, first of all, their reality against possible selection effects. These are best…
Precursors in Swift Gamma Ray Bursts with redshift
D. Burlon, G. Ghirlanda, G. Ghisellini +4
We study a sample of Gamma-Ray Bursts detected by the Swift satellite with known redshift which show a precursor in the Swift-BAT light curve. We analyze the spectra of the precurs…
