Repopulating the pair-instability mass gap without sustained growth to massive IMBHs: the case of 47\,Tuc

Debatri Chattopadhyay, Daniel Marín Pina, Mark Gieles +2

We model the formation and retention of the most massive black hole (BH) in 47~Tuc using the semi-analytical code \texttt{cBHBd}, coupling cluster evolution with binary BH dynamics…
