The environment of weak emission-line quasars
Marek Nikolajuk, Roland Walter
The nature of weak emission-line quasars (WLQs) is probed by comparing the Baldwin effect (BEff) in WLQs and normal quasars (QSOs). We selected 81 high-redshift (z>2.2) and 2 inter…
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 (…
η Carinae: a very large hadron collider
R. Walter, C. Farnier, J. -C. Leyder
Eta Carinae is the colliding wind binary with the largest mass loss rate in our Galaxy and the only one in which hard X-ray emission has been detected. Eta Carinae is therefore a p…
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…
An XMM-Newton Spectral and Timing Study of IGR J16207-5129: An Obscured and Non-Pulsating HMXB
John A. Tomsick, Sylvain Chaty, Jerome Rodriguez +3
We report on a 12 hr XMM-Newton observation of the supergiant High-Mass X-ray Binary IGR J16207-5129. This is only the second soft X-ray (0.4-15 keV, in this case) study of the sou…
Chandra Localizations and Spectra of INTEGRAL Sources in the Galactic Plane
John A. Tomsick, Sylvain Chaty, Jerome Rodriguez +2
We report on the results of observations of hard X-ray sources in the Galactic plane with the Chandra X-ray Observatory. The hard X-ray IGR sources were discovered by the INTEGRAL…
Identifications of Four INTEGRAL Sources in the Galactic Plane via Chandra Localizations
John A. Tomsick, Sylvain Chaty, Jerome Rodriguez +3
Hard X-ray imaging of the Galactic plane by the INTEGRAL satellite is uncovering large numbers of 20-100 keV "IGR" sources. We present results from Chandra, INTEGRAL, optical, and…
