Graviton mass bounds from space-based gravitational-wave observations of massive black hole populations
Graviton mass bounds space-based gravitational-wave observations massive black hole populations
2011/10/17
Space-based gravitational-wave detectors, such as LISA or a similar ESA-led mission, will offer unique opportunities to test general relativity. We study the bounds that space-based detectors could pl...
Discovery and identification of infrared counterpart candidates of four Galactic centre low mass X-ray binaries
X-rays: binaries – infrared: stars – X-rays: individuals: XTE J1637− 498, IGRJ17379− 3747, IGR J17585− 3057, GX9+1
2011/9/30
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 identification problematic; howe...
The Mass Distribution of the Great Attractor as Revealed by a Deep NIR Survey
Distribution Great Attractor Revealed Deep Survey
2011/9/28
This paper presents the analysis of a deep near-infrared J,H,Ks-imaging survey (37.5 sq deg) aimed at tracing the galaxy distribution of the Great Attractor (GA) in the Zone of Avoidance along the so-...
Jets in high-mass microquasars
X-rays: binaries–ISM: jets and outfl ows–Stars: winds, outfl ows–Radiation mechanisms: non-thermal
2011/9/28
The morphologies of detected jets in X-ray binaries are almost as diverse as their number. This is due to different jet properties and ambient media that these jets encounter. It is important to under...
