Discovery of the X-ray Counterpart to the Rotating Radio Transient J1819--1458
S. P. Reynolds, K. J. Borkowski, B. M. Gaensler +10
We present the discovery of the first X-ray counterpart to a Rotating RAdio Transient (RRAT) source. RRAT J1819--1458 is a relatively highly magnetized (B G)…
A Compton reflection dominated spectrum in a peculiar accreting neutron star
Nanda Rea, Luigi Stella, Gian Luca Israel +5
We report on a puzzling event occurred during a long BeppoSAX observation of the slow-rotating binary pulsar GX 1+4. During this event, lasting about 1 day, the source X-ray flux w…
Discovery and Monitoring of the likely IR Counterpart of SGR 1806-20 during the 2004 gamma-ray burst-active state
GianLuca Israel, Stefano Covino, Roberto Mignani +9
The sky region including the Chandra position of SGR 1806-20 was monitored in the IR band during 2004, following its increased high energy bursting activity. Observations were perf…
Discovery of Rapid X-ray Oscillations in the Tail of the SGR 1806-20 Hyperflare
GianLuca Israel, Tomaso Belloni, Luigi Stella +7
We have discovered rapid Quasi Periodic Oscillations (QPOs) in RXTE/PCA measurements of the pulsating tail of the 27th December 2004 giant flare of SGR 1806-20. QPOs at about 92.5H…
A XMM-Newton View of the Soft Gamma-ray Repeater SGR 1806--20: Long Term Variability in the pre-Super Giant Flare Epoch
S. Mereghetti, A. Tiengo, P. Esposito +8
The low energy (<10 keV) X-ray emission of the Soft Gamma-ray Repeater SGR1806-20 has been studied by means of four XMM-Newton observations carried out in the last two years, the l…
