Swift/XRT monitoring of the Supergiant Fast X-ray Transient IGR J18483-0311 for an entire orbital period
P. Romano, L. Sidoli, L. Ducci +9
IGR J18483-0311 is an X-ray pulsar with transient X-ray activity, belonging to the new class of High Mass X-ray Binaries called Supergiant Fast X-ray Transients. This system is one…
The first broad-band X-ray study of the Supergiant Fast X-ray Transient SAXJ1818.6-1703 in outburst
L. Sidoli, P. Romano, P. Esposito +7
The Supergiant Fast X-ray Transient (SFXT) SAXJ1818.6-1703 underwent an outburst on 2009 May 6 and was observed with Swift. We report on these observations which, for the first tim…
Monitoring Supergiant Fast X-ray Transients with Swift. Results from the first year
P. Romano, L. Sidoli, G. Cusumano +12
Swift has allowed the possibility to give Supergiant Fast X-ray Transients (SFXTs), the new class of High Mass X-ray Binaries discovered by INTEGRAL, non serendipitous attention th…
Neutrino Astronomy with IceCube
Tyce DeYoung
IceCube is a kilometer-scale high energy neutrino telescope under construction at the South Pole, a second-generation instrument expanding the capabilities of the AMANDA telescope.…
Structure of the Accretion Flow in Broad-Line Radio Galaxies: The Case of 3C390.3
R. M. Sambruna, J. N. Reeves, V. Braito +8
We present XMM and Suzaku observations of the Broad-Line Radio Galaxy (BLRG) 3C390.3. The Fe Ka line has a width FWHM ~ 8,800 km/s, consistent within a factor two with the width of…
A Chandra view of NGC 3621: a bulgeless galaxy hosting an AGN in its early phase?
M. Gliozzi, S. Satyapal, M. Eracleous +2
We report the detection of a weak X-ray point source coincident with the nucleus of the bulgeless disk galaxy NGC 3621, recently discovered by Spitzer to display high ionization mi…
