Astronomers have apparently discovered a new galactic wallflower, the "lamest" dwarf satellite of the Andromeda Galaxy. 🎉🔭 Meanwhile, IOPscience is more excited about cookies than cosmic phenomena, because who doesn't love reading about space with a side of privacy policy? 🍪😂

An article to be published in "The Astrophysical Journal" reports the discovery of about 2,500 new candidate active galactic nuclei in dwarf galaxies and about 300 new candidate intermediate-mass black holes. A team of researchers examined observations conducted with the Dark Energy Spectroscopic Instrument (DESI) on the Nicholas U. Mayall 4-meter Telescope in Arizona to find all these possible black holes.

An article published in the journal "Nature Astronomy" reports the results of the study of the dwarf galaxy cataloged as LID-568, which has at its center a supermassive black hole that is devouring materials at a rate that is more than 40 times faster than its theoretical limits.

"Now, we are faced with a 'too many satellites problem,' rather than a 'missing satellites problem.'"

Typical. You wait ages to see two #blackholes in #dwarfgalaxies collide them two come along at once. Astronomers caught this type of merger for the first time with NASA’s Chandra X-ray observatory #space telescope. #astronomy #scicomm https://www.space.com/black-holes-two-pairs-collision-courses-chandra
