Prompt and afterglow early X-ray phases in the comoving frame. Evidence for Universal properties?
G. Chincarini, A. Moretti, P. Romano +38
We analyze the Swift XRT light curves and spectra of the gamma-ray bursts (GRBs) for which the redshift has been measured. The sample consists of seven GRBs. The soft X-ray light c…
The REM Telescope: Detecting the Near Infra-Red Counterparts of Gamma-Ray Bursts and the Prompt Behaviour of Their Optical Continuum
F. M. Zerbi, G. Chincarini, G. Ghisellini +1
Observations of the prompt afterglow of Gamma Ray Burst events are unanimously considered of paramount importance for GRB science and related cosmology. Such observations at NIR wa…
Soft Cores in Late-Type Dwarf and LSB Galaxies from HαObservations
D. Marchesini, E. D'Onghia, G. Chincarini +4
We present high spatial resolution Hαrotation curves of late-type dwarf and LSB galaxies. From our analysis we find good agreement between our Hαdata and the HI observations taken…
Dark Matter in the center of galaxies and galaxy clusters: ruling out the CDM scenario?
E. D'Onghia, G. Chincarini, C. Firmani +1
This work is focused on the preliminary results of the observations of Hαrotation curves for some of the late type dwarf and LSB galaxies carried out at the TNG telescope. In light…
The REFLEX Galaxy Cluster Survey IV: The X-ray Luminosity Function
H. Boehringer, C. A. Collins, L. Guzzo +10
The X-ray galaxy cluster sample from the REFLEX Cluster Survey, which covers the X-ray brightest galaxy clusters detected in the ROSAT All-Sky Survey in the southern sky, is used t…
Interpreting the optical data of the Hubble Deep Field South: colors, morphological number counts and photometric redshifts
M. Volonteri, P. Saracco, G. Chincarini +1
We present an analysis of the optical data of the Hubble Deep Field South. We derive F300W(AB), F450W(AB), F606W(AB) and F814W(AB) number counts for galaxies in all four bands. The…
