Study of the relationship between the gamma ray bursts and their host galaxies
S. E. Nuza, P. B. Tissera, L. J. Pellizza +3
Gamma ray bursts (GRBs) belong to the most energetic events in the Universe. Recently, the extragalactic nature of these sources has been confirmed with the discovery of several ho…
GRB 050904 at redshift 6.3: observations of the oldest cosmic explosion after the Big Bang
G. Tagliaferri, L. A. Antonelli, G. Chincarini +10
We present optical and near-infrared observations of the afterglow of the gamma-ray burst GRB 050904. We derive a photometric redshift z = 6.3, estimated from the presence of the L…
Optical emission from GRB 050709: a short/hard GRB in a star forming galaxy
S. Covino, D. Malesani, G. L. Israel +30
We present optical observations of the short/hard gamma-ray burst GRB 050709, the first such event with an identified optical counterpart. The object is coincident with a weak X-ra…
On the local birth place of Geminga
L. J. Pellizza, R. P. Mignani, I. A. Grenier +1
Using estimates of the distance and proper motion of Geminga and the constraints on its radial velocity posed by the shape of its bow shock, we investigate its birth place by traci…
