Axions explain the formation of supermassive black holes at cosmic dawn
Abstract
In a recent paper we pointed out that supermassive black holes, with masses ranging from $10^5$ to $10^{10} M_\odot$ form naturally at cosmic dawn if the dark matter is QCD axions or axion-like particles with mass $m > 10^{-16}\, \mathrm{eV}/c^2$. No additional assumptions are required. Here we answer in detail the most commonly raised questions regarding our work.
