" The theory of supernovae has reached a new level of sophistication and conviction, post Supernova 1987a. This is reflected in a collection of authoritative articles
G. Brown, editor, Physics Reports, 163(1), 1-204, 1988.
"Three recent developments in the continuing quest to identify the ‘dark matter’ making up most of the mass of the Universe are noteworthy:
First, a reported anomalous excess of antiprotons, interpreted as possible evidence in heavy neutrino or photino annihilation, has not been confirmed.
S.P. Ablen, S. Barwick, J.J. Beatty, C.R Bower, G. Gerbier, et al., “New limit on the low-energy antiproton/proton ratio in the galactic cosmic radiation,” Physical Review Letters, 61(2), 145-8, 11 July 1988.
Second. improved experimental limits on possible deposit of energy by scattering of background heavy particles in matter have been reported.
