Observational evidence for intermediate-mass black holes
M Mezcua - International Journal of Modern Physics D, 2017 - World Scientific
Intermediate-mass black holes (IMBHs), with masses in the range 1 0 0–1 0 6 M⊙, are the
link between stellar-mass BHs and supermassive BHs (SMBHs). They are thought to be the …

Evidence for heavy-seed origin of early supermassive black holes from a z ≈ 10 X-ray quasar
Observations of quasars reveal that many supermassive black holes (BHs) were in place
less than 700 Myr after the Big Bang. However, the origin of the first BHs remains a mystery …

Primordial black holes from single field models of inflation
Primordial black holes (PBH) have been shown to arise from high peaks in the matter power
spectra of multi-field models of inflation. Here we show, with a simple toy model, that it is …
