About the gamma-ray burst GRB 060218/SN 2006aj (z=0.033): the most recent observational results and about inevitable changes in "standard"/popular scenarios describing the phenomenon of the gamma-ray burst and explosion of a (massive) supernova. ... The BTA spectra of GRB 060218/SN 2006aj, as well as the BTA spectra of GRB 030329/SN 2003dh (z = 0.1685), turn out again to be among the very first spectra of two nearest GRB/SN-bursts. ...

Next: Ejectors in Massive Binary Previous: Artificial Galaxy: Full Matrix . The first version of the Scenario Machine was aimed especially at the simulation of massive binary star evolution. ... First, there is a large class of intermediate mass binaries (say, consisting initially of 8 + 5 solar masses) that can also produce NS and thus lead to the formation of a bright X-ray source. ...

... Together, this small group works mostly in the field of Active Galactic Nuclei, exploring their distribution in parameter space (black hole mass, black hole spin, accretion rate) and their evolution in cosmic time. Since the growth and activity of the central black hole, on the one side, and the assembly of the host galaxy, on the other, go very tightly in parallel, the AGN evolution is a convenient window on the more general problem of the formation of cosmic structures. ...

... 2014 February 24 . The Cloudy Cores of Active Galaxies . Image Credit: NASA's GSFC , W. Steffen ( UNAM ) . Explanation: What would it look like to travel to the center of an active galaxy? Most galactic centers are thought to house black hole s millions of times more massive than our Sun. The spaces surrounding these supermassive black holes may be far from dormant, however, flickering in many colors and earning the entire object class the title of Active Galactic Nuclei (AGN). ...

... All the parameters provided in this database have been obtained using the the MIRIAD ( Sault et al. 1995 ) task MBSPECT . MBSPECT makes a spectrum of the velocity (or frequency) axis of a cube. The spectrum is beam-weighted, over the width specified, for the other image axes. ... Robust parameters are calculated by using an algorithm which minimises the mean absolute deviation of the flux-weighted velocities. mask= This specifies the x-axis ranges to be excluded from any continuum fit. ...

... Following several successful moon landings,NASA decided to use its last Saturn V not to fly to the moon but to place in low Earth orbit a large space station, named Skylab. ... It was followed that year by three manned flights using the smaller Saturn IB, each carrying 3 astronauts for a prolonged stay aboard Skylab. ... Mass measurements aboard Skylab were part of the medical experiments conducted there. ... Measuring body mass in the M172 chair (see illustration) was not a simple matter. ...
