Simultaneous multiwavelength observations of the Low/Hard State of the X-ray transient source SWIFT J1753.5-0127
M. Cadolle Bel, M. Ribo, J. Rodriguez +11
We report the results of simultaneous multiwavelength observations of the X-ray transient source SWIFT J1753.5-0127 performed with INTEGRAL, RXTE, NTT, REM and VLA on 2005 August 1…
Multi-wavelength observations of the microquasar XTE J1720-318: a transition from high-soft to low-hard state
Sylvain Chaty
To gain a better understanding of high-energy Galactic sources, we observed the Galactic X-ray binary and black hole candidate XTE J1720-318 in the optical and near-infrared, just…
Broad-band spectral changes of the microquasars Cygnus X-1 and SWIFT J1753.5-0127
Marion Cadolle Bel, Marc Ribo, Jerome Rodriguez +3
We report high-energy results obtained with INTEGRAL and Rossi-XTE on two microquasars: the persistent high-mass system Cygnus X-1 and the transient low-mass binary SWIFT J1753.5-0…
Hunting the nature of IGR J17497-2821 with X-ray and NIR observations
A. Paizis, M. A. Nowak, S. Chaty +7
We report on a Chandra grating observation of the recently discovered hard X-ray transient IGR J17497-2821. The observation took place about two weeks after the source discovery at…
Optical to Mid-Infrared observations revealing the most obscured high-energy sources of the Galaxy
Sylvain Chaty, Farid Rahoui
A new type of sources has been discovered by INTEGRAL. These sources are in the course of being unveiled by means of multi-wavelength optical, near- and mid-infrared observations.…
The role of microquasars in astroparticle physics
Sylvain Chaty
I present an overview of past, present and future research on microquasars and jets, showing that microquasars, i.e. galactic jet sources, are among the best laboratories for high…
