Fig. 7 nicely shows how the brightest/most massive galaxies are essentially all slow rotators. Only non-BCG galaxies of somewhat lower mass rotate fast, indicating a history with more gas-rich mergers.

After years of effort Davor Krajnović now published the M3G (MUSE Most Massive Galaxies) survey paper: https://arxiv.org/abs/2602.04968
He shows that from these massive galaxies, the brightest cluster galaxies (BCGs) are all slow rotators.
I think I like Fig. 5 the most, showing an astonishing five spin components in PGC 046832.
