Abstract

Low-metallicity (Z less than or similar to 0.05 Z(circle dot)) massive (greater than or similar to 40 M(circle dot)) stars might end their life by directly collapsing into massive black holes (BHs, 30 less than or similar to m(BH)/M(circle dot) less than or similar to 80). More than similar to 10(5) massive BHs might have been generated v...More
