INTEGRAL and RXTE Observations of Centaurus A
Richard E. Rothschild, Joern Wilms, John Tomsick +6
INTEGRAL and RXTE performed three simultaneous observations of the nearby radio galaxy Cen A in 2003 March, 2004 January, and 2004 February with the goals of investigating the geom…
The Galactic black hole transient H1743-322 during outburst decay: connections between timing noise, state transitions and radio emission
E. Kalemci, J. A. Tomsick, R. E. Rothschild +3
Multi-wavelength observations of Galactic black hole transients during outburst decay are instrumental for our understanding of the accretion geometry and the formation of outflows…
Evolution of the X-Ray Jets from 4U 1755--33
P. Kaaret, S. Corbel, J. A. Tomsick +4
We report on new X-ray observations of the large-scale jets recently discovered in X-rays from the black hole candidate 4U 1755-33. Our observations in 2004 show that the jets foun…
INTEGRAL and XMM-Newton observations of the X-ray pulsar IGR J16320-4751/AX J1631.9-4752
J. Rodriguez, A. Bodaghee, P. Kaaret +16
We report on observations of the X-ray pulsar IGR J16320-4751 (a.k.a. AX J1631.9-4752) performed simultaneously with INTEGRAL and XMM-Newton. We refine the source position and iden…
Discovery of the Millisecond X-Ray Pulsar HETE J1900.1-2455
P. Kaaret, E. H. Morgan, R. Vanderspek +1
We report the discovery of millisecond pulsations from the low-mass X-ray binary HETE J1900.1-2455 which was discovered by the detection of a type I X-ray burst by the High Energy…
On the origin of black hole X-ray emission in quiescence: Chandra observations of XTE J1550-564 and H 1743-322
S. Corbel, J. A. Tomsick, P. Kaaret
We report the results of observations of the black hole binaries XTE J1550-564 and H 1743-322 in their quiescent state using the Chandra X-ray Observatory. Both sources are detecte…
Black Hole Spectral States and Physical Connections
John A. Tomsick
The dramatic changes seen in the X-ray spectral and timing properties of accreting black hole candidates (BHCs) provide important clues about the accretion and jet formation proces…
The Low Quiescent X-Ray Luminosity of the Transient X-Ray Burster EXO 1747-214
John A. Tomsick, Dawn M. Gelino, Philip Kaaret
We report on X-ray and optical observations of the X-ray burster EXO 1747-214. This source is an X-ray transient, and its only known outburst was observed in 1984-1985 by the EXOSA…
Chandra and RXTE Spectra of the Burster GS 1826-238
T. W. J. Thompson, R. E. Rothschild, J. A. Tomsick +1
Using simultaneous observations from Chandra and RXTE, we investigated the LMXB GS 1826-238 with the goal of studying its spectral and timing properties. The uninterrupted Chandra…
Discovery of X-ray Jets in the Microquasar H 1743-322
S. Corbel, P. Kaaret, R. P. Fender +3
We report on the formation and evolution of two large-scale, synchrotron-emitting jets from the black hole candidate H 1743-322 following its reactivation in 2003. In November 2003…
X-Ray Observations of the Black Hole Transient 4U 1630-47 During Two Years of X-Ray Activity
John A. Tomsick, Stephane Corbel, Andrea Goldwurm +1
The black hole candidate (BHC) X-ray transient 4U 1630-47 continuously produced strong X-ray emission for over 2 years during 2002-2004. We use observations made with the Rossi X-r…
