Abstract
In a recent paper \cite{smbh}. 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 $m > 10^{-16}$ eV/$c^2$. No additional assumptions are required. Here we answer in detail the most commonly raised questions regarding our work.
