Scientists have used the Chandra X-ray telescope managed in Alabama to find the first two observable candidates for merging dwarf galaxies that form larger galaxies, fuel black holes and have key roles in space galaxies.
Scientists have found evidence of colliding galaxies in these images taken by NASA's Chandra Space Telescope. Evidence for two pairs of supermassive black holes in dwarf galaxies on collision courses has been found with Chandra.Scientists from the University of Alabama have used the Chandra X-ray telescope managed in Alabama to find the first two observable candidates for merging dwarf galaxies that form larger galaxies, fuel black holes and have key roles in space galaxies.
Marko Mićić, a University of Alabama graduate student in astronomy and physics, led the study. The research was done in the lab of, professor of physics and astronomy. Along with Mićić, a doctoral student originally from Serbia, two undergraduate students, Olivia Holmes, a junior from Tuscaloosa, and Brenna Wells, a junior from Andalusia, are co-authors on the paper.
The scientists named one of the galaxies Mirabilis after an “endangered species of hummingbirds known for their exceptionally large tails.” The second candidate is “associated with two dwarf galaxies in an early-stage merger,” and they were named Elstir and Vinteuil after fictional artists from Marcel Proust’s “In Search of Lost Time.”
“This paper introduces a novel approach of using archival X-ray and infrared observations, coupled with image processing to reveal in faint merging galaxies,” the scientists said, “and even if our targets turn out not to be dwarfs, the approach described in this paper can be used to discover rich populations of .”
