Next: Supernova Explosions Up: No Title Previous: X-ray Luminosity Evolution . The origin of cosmic rays (CR) (especially of very high energies, >  eV) until now has been one of the unsolved problems in modern astrophysics. It is unclear as yet whether one universal mechanism of relativistic particle formation in our Galaxy operates or not, and if there are several different mechanisms, what is their relative contribution to CR formation. ... compact X-ray stars in binary systems. ...

... Chapman and Ferraro (1931, 1932) were first to discuss the existence of a boundary to the Earth's magnetic field.

... If finddead =Y, embadpixfind looks for too dark pixels, rows and columns too. ... The maxratio parameter avoids detecting 'grey' pixels, rows or columns on observations with high statistics. Whatever findbright and finddead , dark and bright columns and rows are always searched for together in order of decreasing significance (either positive or negative). This avoids finding spurious bright columns/rows next to very dark ones, and vice-versa. ...
