Swift monitoring of the new accreting millisecond X-ray pulsar IGRJ17511-3057 in outburst
E. Bozzo, C. Ferrigno, M. Falanga +3
A new accreting millisecond X-ray pulsar, IGR J17511-3057, was discovered in outburst on 2009 September 12 during the INTEGRAL Galactic bulge monitoring programme. To study the evo…
Does the X-ray emission of the luminous quasar RBS 1124 originate in a mildly relativistic outflowing corona?
G. Miniutti, E. Piconcelli, S. Bianchi +2
We have observed the luminous (L_x ~ 6x10^44 erg/s) radio-quiet quasar RBS 1124 (z=0.208) with Suzaku. We report the detection of a moderately broad iron (Fe) line and of a weak so…
Bursting behavior of the Galactic Center faint X-ray transient GRS 1741.9-2853
G. Trap, M. Falanga, A. Goldwurm +6
The neutron star low-mass X-ray binary GRS 1741.9-2853 is a known type-I burster of the Galactic Center. It is transient, faint, and located in a very crowded region, only 10 arcmi…
Swift observations of IGRJ16479-4514 in outburst
E. Bozzo, A. Giunta, L. Stella +3
The supergiant fast X-ray transient source IGR J16479-4514 was observed in outburst two times with Swift. Its quiescent state was investigated in-depth only once in 2008 through a…
The supergiant fast X-ray transient IGRJ18483-0311 in quiescence: XMM-Newton, Swift, and Chandra observations
A. Giunta, E. Bozzo, F. Bernardini +7
IGR J18483-0311 was discovered with INTEGRAL in 2003 and later classified as a supergiant fast X-ray transient. It was observed in outburst many times, but its quiescent state is s…
The first X-ray eclipse of IGRJ16479-4514?
E. Bozzo, L. Stella, G. Israel +2
We report on the first long (~32 ks) pointed XMM-Newton observation of the supergiant fast X-ray transient IGRJ16479-4514. Results from the timing, spectral and spatial analysis of…
