Chandra Localizations and Spectra of INTEGRAL Sources in the Galactic Plane: The Cycle 9 Sample

John A. Tomsick, Sylvain Chaty, Jerome Rodriguez +2

We report on 0.3-10 keV X-ray observations by the Chandra X-ray Observatory of the fields of 22 sources that were discovered as hard X-ray (20-100 keV) sources by the INTEGRAL sate…

X-ray Timing of Stellar Mass Black Holes

John A. Tomsick, Ronald A. Remillard, Jeroen Homan +3

X-ray timing observations of accreting stellar mass black holes have shown that they can produce signals with such short time scales that we must be probing very close to the inner…

Optical Astrometry of Accreting Black Holes and Neutron Stars: Scientific Opportunities

John A. Tomsick, Andreas Quirrenbach, Shrinivas R. Kulkarni +2

The extreme conditions found near black holes and neutron stars provide a unique opportunity for testing physical theories. Observations of both types of compact objects can be use…

The early phase of a H1743-322 outburst observed by INTEGRAL, RXTE, Swift, and XMM/Newton

L. Prat, J. Rodriguez, M. Cadolle Bel +7

We investigate the early phase of the first state change during the 2008 September-November outburst of H1743-322, first detected by the INTEGRAL satellite. We analyse INTEGRAL, RX…

Hard (State) Problems

John A. Tomsick

For microquasars, the one time when these systems exhibit steady and powerful jets is when they are in the hard state. Thus, our understanding of this state is key to learning abou…

Swift follow-up observations of 17 INTEGRAL sources of uncertain or unknown nature

J. Rodriguez, J. A. Tomsick, S. Chaty

(abridged) We analysed data from observations of 17 INTEGRAL sources made with the Swift satellite. We refine the position of the hard X-ray sources to an accuracy of a few arcsec.…
