They make no mention of non-intelligent alien civilisations, in which beings wear red caps reading MAKE THE MILKY WAY GREAT AGAIN, but I assume they’re out there, too.
The paper, published on Monday in The Astrophysical Journal, uses “galactic star formation histories, metallicity distributions, and the likelihood of stars hosting Earth-like planets in their habitable zones, under specific assumptions”.
