Here is what the page “Black holes can grow in bulgeless galaxies without mergers, DESI study of 2,435 galaxies f” contains. Astronomers using the Dark Energy Spectroscopic Instrument (DESI) analyzed 2,435 galaxies with actively feeding black holes and identified 546 bulgeless galaxies—systems lacking a central stellar bulge. Their findings, published in Monthly Notices of the Royal Astronomical Society, suggest that black holes in these bulgeless galaxies grow just as effectively as those in galaxies with prominent bulges. This challenges the long-held view that galaxy mergers and bulge formation are necessary for black hole growth.
The study implies that quiet, secular processes within galaxies can fuel black holes, reshaping our understanding of co-evolution between galaxies and their central black holes. The research points to new avenues for exploring how black holes and their host galaxies evolve together over cosmic time.
