Scientific paper

An examination of the histogram of the radii of supernova remnants allows one to deduce: (1) some support for the existence of a fairly dense galactic halo at least up to a few kpc from the galactic plane; and (2) a first approximation for the initial energy distribution. Although the precise shape is still in doubt and various possibilities exist, one can conclude that the supernova rate should be no less than 1/150 SN per year, and no more than 1/70 SN per year; the average initial energy should be larger than 1.4 times 10 to the 49-th power erg.
