... The hard gamma radiation from AGN is produced most probably in the relativistic jets observed in the considerable part of these objects. In the center of AGN (and may be of all other galaxies) there is a supermassive black hole surrounded by the accretion disk, which is the source of the energy in these objects. ... The problem of particle acceleration in the AGN jets is very important: the time of the electron energy losses in the jets is usually much less than their life time. ... next page . ...

... Spectra obtained with the 6-m telescope of SAO RAS are used along with archival data from Spitzer and several ground-based telescopes to infer a strength of PAH emission, age, properties of the UV radiation field, and metallicity of studied HII complexes. Physical properties (age, radiation field parameters, metallicity) are related to the F 8 /F 24 ratio used as a proxy for the PAH abundance in order to reveal factors that may influence the PAH evolution in HII complexes. ...

... 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. ...

... stars . ... Finding twin Earths is harder than we thought . Astronomers need a handful of transits to decipher a planet's atmosphere and possibly confirm the existence of the first twin Earth. ... If an earthlike world is nearby, though, then by adding observations of a number of transits, astronomers should be able to detect biomarkers like methane or ozone. ... They are also cooler and dimmer than the Sun, as well as smaller, which makes finding an earthlike planet transiting an M star easier. ...
