Modelling the spectral response of the Swift-XRT CCD camera: Experience learnt from in-flight calibration
O. Godet, A. P. Beardmore, A. F. Abbey +11
(Abbreviated) We show that the XRT spectral response calibration was complicated by various energy offsets in photon counting (PC) and windowed timing (WT) modes related to the way…
Multiple flaring activity in the supergiant fast X-ray transient IGR J08408-4503 observed with Swift
P. Romano, L. Sidoli, G. Cusumano +11
IGR J08408-4503 is a supergiant fast X-ray transient discovered in 2006 with a confirmed association with a O8.5Ib(f) supergiant star, HD 74194. We report on the analysis of two ou…
Swift Observations of Shock Evolution in RS Ophiuchi
M. F. Bode, J. P. Osborne, K. L. Page +11
Our \textit{Swift} observations of RS Oph form an unprecedented X-ray dataset to undertake investigations of both the central source and the interaction of the outburst ejecta with…
The SMC SNR 1E0102.2-7219 as a Calibration Standard for X-ray Astronomy in the 0.3-2.5 keV Bandpass
Paul P. Plucinsky, Frank Haberl, Daniel Dewey +8
The flight calibration of the spectral response of CCD instruments below 1.5 keV is difficult in general because of the lack of strong lines in the on-board calibration sources typ…
The short GRB070707 afterglow and its very faint host galaxy
S. Piranomonte, P. D'Avanzo, S. Covino +18
We present the results from an ESO/VLT campaign aimed at studying the afterglow properties of the short/hard gamma ray burst GRB 070707. Observations were carried out at ten differ…
Outliers from the mainstream: how a massive star can produce a gamma-ray burst
S. Campana, N. Panagia, D. Lazzati +12
It is now recognized that long-duration Gamma-Ray Bursts (GRBs) are linked to the collapse of massive stars, based on the association between (low-redshift) GRBs and (type Ic) core…
