. During 10 years, five high-energy cosmic rays (plotted as orange asterisks) came from one small part of the sky near the star Merak in the Big Dipper. Astrophysicists suspect their source is a merging pair of galaxy clusters (blue). Progressively more distant galaxy clusters appear in light blue, green, and red, while the gray shading shows the positional error for each of the five cosmic-ray detections. G. R. Farrar, A. A. Berlind, D. W. Hogg (New York University)

... Seminar archive . ... The structure of the X-ray sources in the hard spectral state of accreting black-hole binaries has been a subject of intense debate. The paradigm dominant for many years postulated that the accretion disc in the hard state is truncated at some radius >> the innermost stable orbit (ISCO) whereas the disc reaches the ISCO in the soft state. ... On the other hand, there have been numerous claims in recent years that the disc extends to the ISCO in the hard state. ...

... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters.

... In the spectrometry of point sources, the advantage of obtaining long slit spectra over using single aperture spectra is that it provides a simultaneous spectrum of the background on both sides of the point source. ... The STECF IRAF layered package "specres" provides two tasks to extract point source spectra from 2-D images (either longslit, multislit or cross-dispersed) and decompose the full background over the image. ... A Point Source Function spectrum image is required as a 2-D spectrum. ...
