Near real-time selection of high redshift GRBs with Swift
S. Campana, G. Tagliaferri, D. Malesani +4
A good fraction of GRBs detected by Swift are at a large redshift (up to z=6.3, so far). Their study allows us to investigate, among other things, the cosmic star formation in the…
Intensity-hardness correlation and deep infrared observation of the anomalous X-ray pulsar 1RXS J170849-400910
N. Rea, G. L. Israel, T. Oosterbroek +6
We report here on X-ray and IR observations of the Anomalous X-ray Pulsar 1RXS J170849-400910. First, we report on new XMM-Newton, Swift-XRT and Chandra observations of this AXP, w…
GRB Radiative Efficiencies Derived from the Swift Data: GRBs vs. XRFs, Long vs. Short
Bing Zhang, Enwei Liang, Kim L. Page +17
We systematically analyze the prompt emission and the early afterglow data of a sample of 31 GRBs detected by {\em Swift} before September 2005, and estimate the GRB radiative effi…
A search for evidence of irradiation in Centaurus X-4 during quiescence
P. D'Avanzo, T. Munoz-Darias, J. Casares +2
We present a study of the neutron star X-Ray Transient Cen X-4. Our aim is to look for any evidence of irradiation of the companion with a detailed analysis of its radial velocity…
An enigmatic long-lasting gamma-ray burst not accompanied by a bright supernova
M. Della Valle, G. Chincarini, N. Panagia +14
Gamma-ray bursts (GRBs) are short, intense flashes of soft gamma-rays coming from the distant Universe. Long-duration GRBs (those lasting more than ~2 s) are believed to originate…
Swift, RXTE, and INTEGRAL observation of Swift J1922.7-1716
M. Falanga, T. Belloni, S. Campana
We report the results of analyzing Swift, RossiXTE, and INTEGRAL data of Swift J1922.7-1716, a likely transient X-ray source discovered by Swift/BAT. Both the fast variability meas…
