We have discovered an X-ray jet due to material ejected from the black hole X-ray transient XTE J1550-564. The discovery was first reported by Corbel et al. (Science, 298, 196 and astro-ph/0210224), and here, we present an analysis of the three Chandra observations made between 2000 ...
black hole. No other X-ray-quiet black hole is unambiguously known outside our Galaxy. The (near-)circular orbit and kinematics of VFTS 243 imply that the collapse of the progenitor into a black hole was associated with little or no ejected material or black-hole kick. Identifying such ...
Black hole physicsGalaxies: activeGalaxies: SeyfertX-rays: binariesLuminous accreting stellar mass and supermassive black holes produce power鈥搇aw continuum X-ray emission from a compact central corona.

For the purpose of understanding the origin of the radio emission, in this paper we investigate the correlation between radio jet and other properties in black hole X-ray binaries (BHXBs). We chose BH systems because there are only two parameters (mass and spin) for a BH, and there is ...
In the past two decades, high-amplitude electromagnetic outbursts have been detected from dormant galaxies and often attributed to the tidal disruption of a star by the central black hole1,2. X-ray emission from the Seyfert 2 galaxy GSN 069 (2MASX J
The bright blue emission that could be seen during the X-ray outburst could be the black hole's disk brightening significantly as it acquires more material from its companion star, the astronomers said. Another strangely behaved ULX from a black hole with an old, companion red giant star was...
We report the results of observations of the black hole binaries XTE J1550-564 and H1743-322 in their quiescent state using the Chandra X-Ray Observatory. Both sources are detected at their faintest level of X-ray emission ever observed with a 0.5-10 keV unabsorbed luminosity of 2 x 10~...
We study X-ray emission from accretion from the interstellar medium on to isolated black holes. Although black holes may be fewer in number than neutron stars, N NS 10 9 , their higher masses, M 9 M , and smaller space velocities, v 40 km s -1 , result in BondiHoyle accretion rates...
