Hints of spin-magnitude correlations and a rapidly spinning subpopulation of binary black holes
Asad Hussain, Maximiliano Isi, Aaron Zimmerman
The complex astrophysical processes leading to the formation of binary black holes and their eventual merger are imprinted on the spins of the individual black holes. We revisit th…
