Distribution of High-Mass X-ray Binaries in the Milky Way
Alexis Coleiro, Sylvain Chaty
Observations of the high energy sky, particularly with the INTEGRAL satellite, have quadrupled the number of supergiant X-ray Binaries observed in the Galaxy, and revealed new popu…
Investigating the Optical Counterpart Candidates of Four INTEGRAL Sources localized with Chandra
Mehtap Özbey Arabacı, Emrah Kalemci, John A. Tomsick +5
We report on the optical spectroscopic follow up observations of the candidate counterparts to four INTEGRAL sources: IGR J04069+5042, IGR J06552-1146, IGR J21188+4901 and IGR J220…
Disentangling the NIR/optical emission of the black hole XTE J1650-500 during outburst
P. A. Curran, S. Chaty, J. A. Zurita Heras
While the sources of X-ray and radio emission in the different states of low-mass X-ray binaries are relatively well understood, the origin of the near-infrared (NIR) and optical e…
X-ray and Near Infrared observations of the obscured accreting pulsar IGR J18179-1621
M. A. Nowak, A. Paizis, J. Rodriguez +6
IGR J18179-1621 is an obscured accreting X-ray pulsar discovered by INTEGRAL on 2012 February 29. We report on our 20 ksec Chandra-High Energy Transmission Gratings Spectrometer ob…
A Chandra observation of the millisecond X-ray pulsar IGR J17511-3057
A. Paizis, M. A. Nowak, J. Rodriguez +4
IGR J17511-3057 is a low mass X-ray binary hosting a neutron star and is one of the few accreting millisecond X-ray pulsars with X-ray bursts. We report on a 20ksec Chandra grating…
Localizing INTEGRAL Sources with Chandra: X-Ray and Multi-Wavelength Identifications and Energy Spectra
John A. Tomsick, Arash Bodaghee, Sylvain Chaty +5
We report on Chandra observations of 18 hard X-ray (>20 keV) sources discovered with the INTEGRAL satellite near the Galactic plane. For 14 of the INTEGRAL sources, we have uncover…
