Optical variability of extragalactic objects, viz., QSOs, BL Lacs and Seyfert galaxies has been monitored systematically over an appreciable period of time and a large amount of data have accumulated....
ON DETERMINATION OF THE COSMIC RAY FLUX USING MOLECULAR HYDROGEN ABSORPTION LINES
Molecular processes-SM molecules-quasars absorption lines

We outline a procedure for estimating the cosmic ray flux at remote
locations where molecular hydrogen absorption lines have been detected. The
method relies on several assumptions whose validity in...
