CMB quenching of high-redshift radio-loud AGNs
G. Ghisellini, F. Haardt, B. Ciardi +4
The very existence of more than a dozen of high-redshift (z>4) blazars indicates that a much larger population of misaligned powerful jetted AGN was already in place when the Unive…
Accessing the population of high redshift Gamma Ray Bursts
G. Ghirlanda, R. Salvaterra, G. Ghisellini +19
Gamma Ray Bursts (GRBs) are a powerful probe of the high redshift Universe. We present a tool to estimate the detection rate of high-z GRBs by a generic detector with defined energ…
The clustering of the luminosities of optical afterglows of long Gamma Ray Bursts
M. Nardini, G. Ghisellini, G. Ghirlanda +3
We studied the optical afterglows of the 24 pre-Swift Gamma-Ray Bursts with known spectroscopic redshift and published estimates of the optical extinction in the source frame. We f…
GRB 020813: polarization in the case of a smooth optical decay
J. Gorosabel, E. Rol, S. Covino +35
We present the results of a VLT polarimetric monitoring campaign of the GRB 020813 optical afterglow carried out in three nights, from 0.88 to 4.20 days after the gamma-ray event.…
Optical and NIR Observations of the Afterglow of GRB 020813
S. Covino, D. Malesani, F. Tavecchio +28
We present optical and near-infrared (NIR) photometry of the bright afterglow of GRB 020813. Our data span from 3 hours to 4 days after the GRB event. A rather sharp achromatic bre…
The X-ray afterglow of GRB030329
A. Tiengo, S. Mereghetti, G. Ghisellini +3
We report on XMM-Newton and Rossi-XTE observations of the bright (fluence 10 erg cm) and nearby (z=0.1685) Gamma-Ray Burst GRB030329 associated to SN2003dh. Th…
