Dust scattering X-ray expanding rings around gamma-ray bursts
S. Mereghetti, A. Tiengo, G. Vianello
Scattering by dust grains in our Galaxy can produce X-ray halos, visible as expanding rings, around GRBs. This has been observed in three GRBs to date, allowing to derive accurate…
Long term spectral variability in the Soft Gamma-ray Repeater SGR 1900+14
A. Tiengo, P. Esposito, S. Mereghetti +8
We present a systematic analysis of all the BeppoSAX data of SGR1900+14. The observations spanning five years show that the source was brighter than usual on two occasions: ~20 day…
Swift and XMM observations of the dark GRB 050326
A. Moretti, A. De Luca, D. Malesani +30
We present Swift and XMM observations of GRB 050326, detected by Swift-BAT. The fluence was 7.7x10^-6 erg cm^-2 (20-150 keV), and its spectrum was hard, with a power law photon ind…
XMM-Newton Spectroscopy of the Accretion-Driven Millisecond X-ray Pulsar XTE J1751-305 in Outburst
J. M. Miller, R. Wijnands, M. Mendez +6
We present an analysis of the first high-resolution spectra measured from an accretion-driven millisecond X-ray pulsar in outburst. We observed XTE J1751-305 with XMM-Newton on 200…
The X-ray Source at the Center of the Cassiopeia A Supernova Remnant
S. Mereghetti, A. Tiengo, G. L. Israel
We present the first results of an XMM-Newton observation of the central X-ray source in the Cas A supernova remnant. The spectrum can be fit equally well with an absorbed steep po…
The Anomalous X-ray Pulsar 1E 1048.1-5937: Phase resolved spectroscopy with the XMM-Newton satellite
A. Tiengo, E. Goehler, R. Staubert +1
We report on an observation of the Anomalous X-ray Pulsar 1E 1048.1-5937 performed with the XMM-Newton satellite. The phase averaged spectrum of 1E 1048.1-5937 is well described by…
The central region of M31 observed with XMM-Newton. II. Variability of the individual sources
J. P. Osborne, K. N. Borozdin, S. P. Trudolyubov +13
We present the results of a study of the variability of X-ray sources in the central 30' of the nearby Andromeda Galaxy (M31) based on XMM Performance Verification observations. Tw…
The European Photon Imaging Camera on XMM-Newton: The MOS Cameras
M. J. L. Turner, A. Abbey, M. Arnaud
The EPIC focal plane imaging spectrometers on XMM-Newton use CCDs to record the images and spectra of celestial X-ray sources focused by the three X-ray mirrors. There is one camer…
The Extended X-ray Halo of the Crab-like SNR G21.5-0.9
R. S. Warwick, J-P. Bernard, F. Bocchino +12
Recent XMM-Newton observations reveal an extended (150") low-surface brightness X-ray halo in the supernova remnant G21.5-0.9. The near circular symmetry, the lack of any limb brig…
The central region of M31 observed with XMM-Newton (I. Group properties and diffuse emission)
R. Shirey, R. Soria, K. Borozdin +13
We present the results of a study based on an XMM-Newton Performance Verification observation of the central 30 arcmin of the nearby spiral galaxy M31. In the 34-ks European Photon…
The first XMM-Newton spectrum of a high redshift quasar - PKS 0537-286
J. N. Reeves, M. J. L. Turner, P. J. Bennie +6
We present XMM-Newton observations of the high redshift z=3.104, radio-loud quasar PKS 0537-286. The EPIC CCD cameras provide the highest signal-to-noise spectrum of a high-z quasa…
