Swift Follow-up Observations of INTEGRAL Sources of Unknown Nature
J. Rodriguez, J. A. Tomsick, S. Chaty
(Abridged) We made use of X-ray observations with the X-ray telescope on-board the \swift observatory to refine the X-ray position to 3-5" accuracy of 12 INTEGRAL sources, so as to…
Recycling Matter in the Universe. X-ray observations of SBS 1150+599A (PN G135.9+55.9)
Gagik Tovmassian, John Tomsick, Ralf Napiwotzki +4
We present X-ray observations of the close binary nucleus of the planetary nebula SBS 1150+599A obtained with the XMM-Newton satellite. Only one component of the binary can be obse…
Linking Jet Emission, X-ray States and Hard X-ray Tails in the Neutron Star X-ray Binary GX 17+2
S. Migliari, J. C. A. Miller-Jones, R. P. Fender +7
We present the results from simultaneous radio (Very Large Array) and X-ray (Rossi-X-ray Timing Explorer) observations of the Z-type neutron star X-ray binary GX~17+2. The aim is t…
Tracing the jet contribution to the mid-IR over the 2005 outburst of GRO J1655-40 via broadband spectral modeling
S. Migliari, J. A. Tomsick, S. Markoff +6
We present new results from a multi-wavelength (radio/infrared/optical/X-ray) study of the black hole X-ray binary GRO J1655-40 during its 2005 outburst. We detected, for the first…
The spectral energy distribution of quiescent black hole X-ray binaries: new constraints from Spitzer
E. Gallo, S. Migliari, S. Markoff +5
(Abridged) Among the various issues that remain open in the field of accretion onto black hole X-ray binaries (BHBs) is the way the gas accretes at very low Eddington ratios, in th…
Uncovering the Nature of the X-ray Transient 4U 1730-22: Discovery of X-ray Emission from a Neutron Star in Quiescence with Chandra
John A. Tomsick, Dawn M. Gelino, Philip Kaaret
The X-ray transient, 4U 1730-22, has not been detected in outburst since 1972, when a single outburst was detected by the Uhuru satellite. This neutron star or black hole X-ray bin…
