Formation of black holes in the dark [HEAP]

http://arxiv.org/abs/1609.08411

A binary black hole (BBH) with components of 30-40 solar masses as the source of gravitational waves GW150914 can be formed from a relatively isolated binary of massive stars if both BHs are formed by implosion, namely, by complete or almost complete collapse of massive stars with no energetic SNe accompanied by a sudden mass loss that would significantly reduce the mass of the compact objects, and in most cases unbind the binary system. 244 more words

Given the title of my website I could hardly resist reblogging this arXiver post. I'm not an expert on Black Hole (BH) formation, so would be interested to hear opinions on how plausible is this idea that massive BHs might form via implosion rather than following a Supernova explosion.

The historic detection of gravitational waves announced earlier this year breathed new life into a theory that’s been around for decades: that black holes created in the first second of the universe might make up dark matter. 1,279 more words
