Black holes grow quietly with bulgeless galaxies, no mergers needed

Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using DESI data and identified 546 bulgeless systems. Published in Monthly Notices of the Royal Astronomical Society, the work suggests black holes grow just as effectively without galaxy mergers.

• 2,435 galaxies with active black holes studied using DESI data
• 546 bulgeless galaxies identified in the sample
• Black hole growth does not require galaxy mergers
