... Orbiting a Black Hole . ... Credit Copyright: Robert Nemiroff ( MTU ) Explanation: What would it look like to orbit a black hole? ... For one thing, the entire sky would be visible , since even stars behind the black hole would have their light bent to the observer's eye. For another, the sky near the black hole would appear significantly distorted , with more and more images of the entire sky visible increasingly near the black hole. ...

... NASA's Hubble Space Telescope has provided a never-before-seen view of a warped disk flooded with a torrent of ultraviolet light from hot gas trapped around a suspected massive black hole. ... This composite image of the core of the galaxy was constructed by combining a visible light image taken with Hubble's Wide Field Planetary Camera 2 (WFPC2), with a separate image taken in ultraviolet light with the Faint Object Camera (FOC). ... The inset box shows Hubble Space Telescope's field of view. ...

... The event horizon is the boundary of a black hole) . ... When the supermassive star implodes (collapses under it?s own gravity) a black hole is formed. Many black holes have been found in the centres of galaxies. ... It was thought that black holes don?t give out any energy at all (except when engulfing stars). ... It is thought that as the stars pass near to the centre, they are pulled in by the black hole and forced to remain orbiting around the black hole. ...

... SS433 is a close binary system, one star is a supergiant, a second one is a black hole. ... Even a black hole cannot accept such an enormous mass flux, a supercritical accretion disk appears, all the excess gas glows up to several tens of thousands degrees and is ejected off the disk with enormous velocities. ... SAO researchers have found an evidence of the supercritical accretion onto a black hole in SS433, which follows from a brightness variability of the SS433 disk. ...

... V4641 Sgr is known as a detached binary containing a 9 Msol. black hole and an A0 type companion. ... Spectra of V4641 Sgr were taken by us using SAO 1-m telescope between May 23.972 and 24.002 UT (the orbital phase of 0.35), wavelength range 3900-7500A, resolution 8A, S/N~30-40. ... These observations show essential light excess over the quiet light level seen only in the orbital phases between -0.25 and +0.25 with the maximum value of 0.15 mag in the V band at the black hole inferior conjunction. ...

... Plate bending . ... The plug-plates of SDSS project are responsible for locating the optical-fiber plugs spatially and for defining the plug tilt with respect to the surface of best focus. ... It can be seen from the graphs that after bending the plate and adding a central suport, the curvature of the plate was quite near that of the desired Kent005 curve. ... Upon adding a central support, however, the slope of the plate decreases to a value slightly less than that of the Kent005 curve. ...

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...

The direct detection of gravitational waves is one of those events long-expected by physicists that are nevertheless a significant occurrence which excites the world scientific community as if something unexpected has happened. ... Many rumors leaked ahead of the conference, and the fact that something (that is, a signal corresponding to gravitational waves) was discovered by LIGO (Laser Interferometer Gravitational-Wave Observatory) was discussed on the sidelines. ... arXiv:1602.03868 . ...

... STFC/JBO/MERLIN Fatal Beauty This composite image (about 180 000 light years across) shows the jet from the black hole at the centre of one galaxy striking another galaxy, the first time such an interaction has been found. ... The proximity of the two galaxies (around twenty thousand light years, about the same distance Earth is from the centre of the Milky Way) means that any planetary systems in the path of the deadly jet are likely to have been destroyed. ...

Inside the rotating or charged black holes there are bound periodic planetary orbits, which not coming out nor terminated at the central singularity. The stable periodic orbits inside black holes exist even for photons. ... It is shown that an existence domain for the third kind orbits is a rather spacious, and so there is a place for life inside the supermassive black holes in the galactic nuclei. ...
