This trove of black holes had been previously overlooked, making this finding a key to our understanding of black holes in dwarf galaxies.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0 \u00a0 \u00a0 \u00a0Black holes are typically detected when they are consuming gas and stardust, which makes them glow intensely. When they are not glowing, we are not able to detect them.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0 \u00a0 \u00a0 \u00a0The problem is that black holes and newborn stars can emit a similar glow. Astronomers have a set of diagnostic tests that allows them to differentiate black holes and newborn stars. However, when the research team applied these tests to their data, they received mixed results. Two tests would indicate black holes, while the third test would indicate a star formation.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0 \u00a0 \u00a0 \u00a0Research study coauthor Sheila Kannappan suspected that they might be undiscovered black holes in a dwarf galaxy. Coauthor Chris Richardson ran theoretical simulations with the mixed results and confirmed that the tests would match with a highly star-forming dwarf galaxy containing a growing massive black hole.\u00a0<\/span><\/p>\n<p><img decoding=\"async\" class=\"size-medium wp-image-37281 aligncenter\" src=\"https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res-300x300.jpg 300w, https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res-500x500.jpg 500w, https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res-100x100.jpg 100w, https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res-150x150.jpg 150w, https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res-250x250.jpg 250w, https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res.jpg 600w, https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res-24x24.jpg 24w, https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res-36x36.jpg 36w, https:\/\/nstem.org\/staging\/wp-content\/uploads\/2022\/06\/Black_hole_-_Messier_87_crop_max_res-48x48.jpg 48w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p style=\"text-align: center;\"><a class=\"\u201dno-link-icon\u201d\" href=\"https:\/\/en.wikipedia.org\/wiki\/File:Black_hole_-_Messier_87_crop_max_res.jpg\" target=\"_blank\" rel=\"noopener\"><strong>Source<\/strong><\/a><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0 \u00a0 \u00a0 \u00a0Mugdha Polimera, leading author of the study and Ph.D. student, set to work obtaining measurements, traditional and mixed message results, and surveys to test for black holes to confirm their work.
