A new measurement of the cosmic X-ray background
A. Moretti, C. Pagani, G. Cusumano +14
We present a new measurement of the cosmic X-ray background (CXRB) in the 1.5-7 keV energy band, performed by exploiting the Swift X-ray telescope (XRT) data archive. We also prese…
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…
High-Resolution X-ray Spectroscopy of SNR 1987A: Chandra LETG and HETG Observations in 2007
Svetozar A. Zhekov, Richard McCray, Daniel Dewey +4
We present an extended analysis of the deep Chandra LETG and HETG observations of the supernova remnant 1987A (SNR 1987A) carried out in 2007. The global fits to the grating spectr…
Nonthermal X-Rays from Supernova Remnant G330.2+1.0 and the Characteristics of its Central Compact Object
Sangwook Park, Oleg Kargaltsev, George G. Pavlov +5
We present results from our X-ray data analysis of the SNR G330.2+1.0 and its CCO, CXOU J160103.1--513353 (J1601). Using our XMM-Newton and Chandra observations, we find that the X…
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…
AGILE detection of delayed gamma-ray emission from GRB 080514B
A. Giuliani, S. Mereghetti, F. Fornari +55
GRB 080514B is the first gamma ray burst (GRB), since the time of EGRET, for which individual photons of energy above several tens of MeV have been detected with a pair-conversion…
