Most today's cosmologists think that dark matter is made of some sort of weakly interacting massive particles filling the Universe. Massive neutrinos have long been considered as possible candidates. Cowsik & McClelland  were the first to draw the attention of the astrophysical community to massive neutrinos. Their work is of relevance here, as they compared their model to the observations of Coma. In their acknowledgments, we can read:
Our interest in the problem of the Coma cluster started after listening to the excellent seminars on the subject by Professors Ivan R. King, Eugene D. Commins, and Joseph Silk.
