Milky Way X-ray background emission « »: , . ... RXTE , . ... Using near-infrared Galaxy intensity measured with COBE/DIRBE experiment and X-ray data from RXTE and INTEGRAL it was shown that X-ray brightness of the Galactic background emission closely follows its stellar density and can be explained by a cumulative emission of a large number of weak Galactic X-ray sources. ... Map of Galactic background emission in hard X-ray energy band obtained with INTEGRAL observatory. ... 2006, &, 452, 169 ., ...

GMATCH . That projects is aimed for the solution of the well known problem of all observational astronomers -- the WCS alignement of the images. It is always great to have the possibility to determine the exact J2000 coordinates of each point of the frame. It is always great to not manually align the images before summing them. My program is aimed to solve all those problems. ... Download . ... WCSLIB library (by M. Calabretta)(download from here ) . ...

Disastrous earthquakes happen 100 to 200 times a year. ... There is a chance that the data of ionospheric plasma observations hold an answer to the latter question. Satellites and ground-based facilities may detect earthquake precursors in the ionosphere a few hours or days before the main shock. ... ULF "Hz"-oscillations have been recorded several hours before the main shock in a narrow magnetic field tube (40...100 km along the satellite trajectory) conjugated with epicenter of the earthquake. ...
