Discovery of Pulsations and a Possible Spectral Feature in the X-ray Emission from Rotating Radio Transient J1819-1458
M. A. McLaughlin, N. Rea, B. M. Gaensler +7
PSR J1819-1458 is a rotating radio transient (RRAT) source with an inferred surface dipole magnetic field strength of 5e13 G and a 4.26-s spin period. We present XMM-Newton observa…
Studies of Neutron Stars at Optical/IR Wavelengths
R. P. Mignani, S. Bagnulo, A. De Luca +7
In the last years, optical studies of Isolated Neutron Stars (INSs) have expanded from the more classical rotation-powered ones to other categories, like the Anomalous X-ray Pulsar…
XMM-Newton observation of the Soft Gamma Ray Repeater SGR 1627-41 in a low luminosity state
S. Mereghetti, P. Esposito, A. Tiengo +6
The sky region containing the soft gamma-ray repeater SGR 1627-41 has been observed three times with XMM-Newton in February and September 2004. SGR 1627-41 has been detected with a…
Pronounced long term flux variability of the Anomalous X-ray Pulsar 1E1048.1-5937
S. Mereghetti, A. Tiengo, L. Stella +4
We present XMM-Newton and Chandra observations of 1E1048.1-5937, being the first to show evidence for a significant variation in the X-ray luminosity of this Anomalous X-ray Pulsar…
BeppoSAX observations of a new X-ray burster in the Galactic Center region, possibly coincident with a recurrent transient
L. Sidoli, S. Mereghetti, G. L. Israel +3
We report BeppoSAX NFI observations of the X-ray source SAX~J1747.0--2853 recently discovered in the region of the Galactic Center. The presence of type I X-ray bursts indicates th…
