... Ultraluminous X-ray sources (ULXs) are located in external galaxies, their X-ray luminosities (10 39 - 10 41 erg/s) are thousand times greater than those of brightest black holes in the Galaxy. ULXs may be supercritical accretion disks around black holes of stellar masses (~10 Solar masses) like that in SS433, or they may be a hypothetical intermediate-mass black holes (hundreds - thousands Solar masses) with standard accretion disks. ... 2) The ULX progenitors were ejected from the star clusters. ...

Next: Cyg X-1 as a Up: Black Holes in Binaries Previous: Black Hole Creation in . The discovery of binary radiopulsars with massive unseen companions ( >3- ) would be of great importance to fundamental physics and modern theory of stellar evolution, providing a compelling evidence for the existence of BH in nature. The formation of binaries consisting of a BH in a pair with a radiopulsar (PSR) has been discussed previously by Narayan et al. ... Здесь должна быть Table 11 (Note к Table 11) . ...

... One of these works directly on an event list, avoiding the losses which occur when events are binned into images. ... A much better solution would be to avoid forming images at all and apply maximum likelihood to the raw event list. ... Rapid access to the event data was also essential. ... Simulating a suitably realistic sky with added sources takes long enough in the image domain, the generation of a sufficiently large set of photon-event lists with similar properties would have taken even longer....
