DESI uncovers 300 intermediate-mass black holes plus 2,500 active black holes in dwarf galaxies

DESI Found 300 Candidate Intermediate Mass Black Holes

If Intermediate-Mass Black Holes (IMBHs) are real, astronomers expect to find them in dwarf galaxies and globular clusters. There’s tantalizing evidence that they exist but no conclusive proof. So far, there are only candidates. The Dark Energy Spectroscopic Instrument (DESI) has found 300 additional candidate IMBHs. Logic says that IMBHs should exist. We know of stellar-mass black holes, and we know of supermassive black holes (SMBHs). Stellar-…

2,500 New Active Black Holes Identified, Raising Questions About How They Evolve

Dark Energy Spectroscopic Instrument (DESI) finds actively feeding black holes and a host of other black hole candidates.

300 new intermediate-mass black holes plus 2500 new active black holes in dwarf galaxies discovered

Within the Dark Energy Spectroscopic Instrument's early data, scientists have uncovered the largest samples ever of intermediate-mass black holes and dwarf galaxies hosting an active black hole, more than tripling the existing census of both. These large statistical samples will allow for more in-depth studies of the dynamics between dwarf galaxy evolution and black hole growth, and open up vast discovery potential surrounding the evolution of t…

Largest-ever discovery of 'missing link' black holes revealed by dark energy camera

Using a revolutionary dark energy camera, astronomers have discovered the largest haul of "missing link" intermediate-mass black holes ever seen, but there should have been more.

DESI uncovers 300 intermediate-mass black holes plus 2,500 active black holes in dwarf galaxies

Using early data from the Dark Energy Spectroscopic Instrument (DESI), a team of scientists have compiled the largest sample ever of dwarf galaxies that host an actively feeding black hole, as well as the most extensive collection of intermediate-mass black hole candidates to date.

Treasure trove of mysterious black holes uncovered by dark energy instrument

Where are all the medium-sized black holes? New data has located the largest collection yet.
