What factors impact how long it takes for a supermassive black hole binary to merge? This composite infrared and X-ray image combines data from JWST and the Chandra X-ray Observatory to illuminate the merging spiral galaxies NGC 2207 (right) and IC 2163 (left). X-ray: NASA / CXC / SAO; Infrared: NASA / ESA / CSA / STScI / Webb; Image Processing: NASA / CXC / SAO / L. Frattare What factors impact how long it takes for a supermassive black hole binary to merge? New research investigates the influence of orbital inclination on the population of merging black holes in our universe. One Merger Leads to Another When galaxies merge, the supermassive black holes at their centers are thought to link up in a binary system and eventually merge as well.…
