X-ray broad-band study of the symbiotic X-ray binary 4U 1954+31
N. Masetti, E. Rigon, E. Maiorano +5
(Abridged) We present results of several X-ray observations of the X-ray binary 4U 1954+31 performed with the satellites BeppoSAX, EXOSAT, ROSAT, RXTE, and Swift. We also studied t…
Gamma Ray Bursts Flares detected and observed by the Swift Satellite
Guido Chincarini, Alberto Moretti, Patrizia Romano +11
The detection of flares with the Swift satellite triggered a lot of bservational and theoretical interest in these phenomena. As a consequence a large analysis effort started withi…
Panchromatic study of GRB 060124: from precursor to afterglow
P. Romano, S. Campana, G. Chincarini +35
We present observations of GRB 060124, the first event for which both the prompt and the afterglow emission could be observed simultaneously and in their entirety by the three Swif…
A metal rich molecular cloud surrounds GRB 050904 at redshift 6.3
S. Campana, D. Lazzati, E. Ripamonti +7
GRB050904 is the gamma-ray burst with the highest measured redshift. We performed time resolved X-ray spectroscopy of the late GRB and early afterglow emission. We find robust evid…
Swift observations of GRB050904: the most distant cosmic explosion ever observed
G. Cusumano, V. Mangano, G. Chincarini +30
Swift discovered the high redshift (z=6.29) GRB050904 with the Burst Alert Telescope (BAT) and began observing with its narrow field instruments 161 s after the burst onset. This g…
Long-term monitoring of the X-ray afterglow of GRB 050408 with Swift/XRT
M. Capalbi, D. Malesani, M. Perri +20
We present observations of the X-ray afterglow of GRB 050408, a gamma-ray burst discovered by HETE-II. Swift began observing the field 42 min after the burst, performing follow-up…
The Swift X-ray flaring afterglow of GRB 050607
Claudio Pagani, David C. Morris, Shiho Kobayashi +22
The unique capability of the Swift satellite to perform a prompt and autonomous slew to a newly detected Gamma-Ray Burst (GRB) has yielded the discovery of interesting new properti…
The X-ray afterglow of the short gamma ray burst 050724
S. Campana, G. Tagliaferri, D. Lazzati +23
Short duration (<2 s) Gamma-ray bursts (GRBs) have been a mystery since their discovery. Until May 2005 very little was known about short GRBs, but this situation has changed rapid…
Swift XRT Observations of the Afterglow of XRF 050416A
Vanessa Mangano, Valentina La Parola, Giancarlo Cusumano +20
Swift discovered XRF 050416A with the BAT and began observing it with its narrow field instruments only 64.5 s after the burst onset. Its very soft spectrum classifies this event a…
The multiwavelength afterglow of GRB 050721: a puzzling rebrightening seen in the optical but not in the X-ray
L. A. Antonelli, V. Testa, P. Romano +27
Context. GRB050721 was detected by Swift and promptly followed-up, in the X-ray by Swift itself and, in the optical band, by the VLT operated, for the first time, in rapid response…
The shock break-out of GRB 060218/SN 2006aj
S. Campana, V. Mangano, A. J. Blustin +36
Although the link between long Gamma Ray Bursts (GRBs) and supernovae (SNe) has been established, hitherto there have been no observations of the beginning of a supernova explosion…
GRB051210: Swift detection of a short gamma ray burst
V. La Parola, V. Mangano, D. Fox +19
The short/hard GRB051210 was detected and located by the Swift-BAT instrument and rapidly pointed towards by the narrow field instrumens. The XRT was able to observe a bright X-ray…
Late-Time X-ray Flares during GRB Afterglows: Extended Internal Engine Activity
A. D. Falcone, D. N. Burrows, P. Romano +21
Observations of gamma ray bursts (GRBs) with Swift produced the initially surprising result that many bursts have large X-ray flares superimposed on the underlying afterglow. These…
Panchromatic study of GRB 060124: from precursor to afterglow
P. Romano, S. Campana, G. Chincarini +35
We present observations of GRB 060124, the first event for which both the prompt and the afterglow emission could be observed simultaneously and in their entirety by the three Swif…
INTEGRAL observations of the Crab pulsar
T. Mineo, C. Ferrigno, L. Foschini +5
The paper presents the timing and spectral analysis of several observations of the Crab pulsar performed with INTEGRAL in the energy range 3-500 keV. All these observations, when s…
X-ray flare in XRF 050406: evidence for prolonged engine activity
P. Romano, A. Moretti, P. L. Banat +33
We present observations of XRF 050406, the first burst detected by Swift showing a flare in its X-ray light curve. During this flare, which peaks at t_peak ~210s after the BAT trig…
