Supergiant X-ray binaries observed by Suzaku
A. Bodaghee, J. A. Tomsick, J. Rodriguez +4
Suzaku observations are presented for the high-mass X-ray binaries IGR J16207-5129 and IGR J17391-3021 (=XTE J1739-302). For IGR J16207-5129, we provide the first X-ray broadband (…
IGR J17448-3232 point source: A blazar candidate viewed through the Galactic centre?
P. A. Curran, S. Chaty, J. A. Zurita Heras +2
The error region of the INTEGRAL source, IGR J17448-3232, contains an X-ray point source at the edge of a ~3' radius extended X-ray source. It has been suggested that the extended…
A search for near infrared counterparts of 3 pulsar wind nebulae
P. A. Curran, S. Chaty, J. A. Zurita Heras +1
While pulsar wind nebulae (PWNe) and their associated isolated pulsars are commonly detected at X-ray energies, they are much rarer at near infrared (nIR) and optical wavelengths.…
Discovery and identification of infrared counterpart candidates of four Galactic centre low mass X-ray binaries
P. A. Curran, S. Chaty, J. A. Zurita Heras
The near infrared (nIR)/optical counterparts of low mass X-ray binaries (LMXBs) are often observationally dim and reside in high source density fields which make their identificati…
Distribution of High Mass X-ray Binaries in the Milky Way
Alexis Coleiro, Sylvain Chaty
The INTEGRAL satellite, observing the sky at high energy, has quadrupled the number of supergiant X-ray Binaries known in the Galaxy and has revealed new populations of previously…
Discovery of the infrared counterpart of CXOU J174437.3-323222 in the field of IGR J17448-3232: a blazar candidate viewed through the Galactic centre?
P. A. Curran, S. Chaty, J. A. Zurita Heras +2
We present our near infrared ESO-NTT Ks band observations of the field of IGR J17448-3232 which show no extended emission consistent with the SNR but in which we identify a new cou…
Nature, formation and evolution of High Mass X-ray Binaries
Sylvain Chaty
The aim of this review is to describe the nature, formation and evolution of the three kinds of high mass X-ray binary (HMXB) population: i. systems hosting Be stars (BeHMXBs), ii.…
Unveiling the nature of IGR J17177-3656 with X-ray, NIR and Radio observations
A. Paizis, M. A. Nowak, J. Wilms +6
We report on the first broad-band (1-200 keV) simultaneous Chandra-INTEGRAL observations of the recently discovered hard X-ray transient IGR J17177-3656 that took place on 2011, Ma…
Observations of the young supernova remnant RX J1713.7-3946 with the Fermi Large Area Telescope
A. A. Abdo, Fermi LAT Collaboration
We present observations of the young Supernova remnant (SNR) RX J1713.7-3946 with the Fermi Large Area Telescope (LAT). We clearly detect a source positionally coincident with the…
Discovery of High-Energy Gamma-Ray Emission from the Binary System PSR B1259-63/LS 2883 Around Periastron with Fermi
A. A. Abdo, Fermi LAT Collaboration, M. Chernyakova +3
We report on the discovery of \geq 100 MeV γ rays from the binary system PSR B1259-63/LS 2883 using the Large Area Telescope (LAT) on board Fermi. The system comprises a radio puls…
Near-infrared jet emission in the microquasar XTE J1550-564
Sylvain Chaty, Guillaume Dubus, Anand Raichoor
Context: Microquasars are accreting Galactic sources that are also observed to launch relativistic jets. A key signature of the ejection is non-thermal radio emission. The level of…
