The dust-scattering X-ray rings of the anomalous X-ray pulsar 1E 1547.0-5408
A. Tiengo, G. Vianello, P. Esposito +14
On 2009 January 22 numerous strong bursts were detected from the anomalous X-ray pulsar 1E 1547.0-5408. Swift/XRT and XMM-Newton/EPIC observations carried out in the following two…
XMM-Newton and Swift observations prove GRB 090709A to be a distant, standard, long GRB
A. De Luca, P. Esposito, G. L. Israel +4
GRB 090709A is a long gamma-ray burst (GRB) discovered by Swift, featuring a bright X-ray afterglow as well as a faint infrared transient with very red and peculiar colors. The bur…
The discovery of a massive white dwarf in the peculiar binary system HD 49798/RX J0648.0-4418
S. Mereghetti, A. Tiengo, P. Esposito +3
An XMM-Mewton observation performed in May 2008 has confirmed that the 13 seconds pulsations in the X-ray binary HD 49798/RX J0648.0-4418 are due to a rapidly rotating white dwarf.…
XMM-Newton observation of the persistent Be/NS X-ray binary pulsar RX J1037.5-5647 in a low luminosity state
N. La Palombara, L. Sidoli, P. Esposito +2
The spectra of several X-ray binary pulsars display a clear soft excess, which in most cases can be described with a blackbody model, above the main power-law component. While in t…
The first outburst of the new magnetar candidate SGR 0501+4516
Nanda Rea, GianLuca Israel, Roberto Turolla +17
We report here on the outburst onset and evolution of the new Soft Gamma Repeater SGR 0501+4516. We monitored the new SGR with XMM-Newton starting on 2008 August 23, one day after…
Strong bursts from the anomalous X-ray pulsar 1E 1547.0-5408 observed with the INTEGRAL/SPI Anti-Coincidence Shield
S. Mereghetti, D. Gotz, G. Weidenspointner +9
In January 2009, multiple short bursts of soft gamma-rays were detected from the direction of the anomalous X-ray pulsar 1E 1547.0-5408 by different satellites. Here we report on t…
