New studies with Chandra and ESA&rsquo;s XMM-Newton show  that these two sources may be intermediate-mass black holes, with masses  in between those of the stellar-mass and supermassive variety. These  &ldquo;survivor&rdquo; black holes avoided falling into the center of the galaxy and  could be examples of the seeds required for the growth of supermassive  black holes in galaxies, including the one in the Milky Way.<\/p><p>This is the first case where good evidence for more than one mid-sized  black hole exists in a single galaxy. The evidence comes from how their  X-ray emission varies over time and analysis of their X-ray brightness  and spectra, i.e., the distribution of X-rays with energy. These results  are interesting because they may help address the mystery of how  supermassive black holes in the centers of galaxies form. M82 is located  about 12 million light years from Earth and is the nearest place to us  where the conditions are similar to those in the early Universe, with  lots of stars forming.<\/p><p>Multiple observations of M82 have been  made with Chandra beginning soon after launch. The Chandra data shown  here were not used in the new research because the X-ray sources are so  bright that some distortion is introduced into the X-ray spectra. To  combat this, the pointing of Chandra is changed so that images of the  sources are deliberately blurred, producing fewer counts in each pixel.<\/p><p><em>Image credit: NASA\/CXC\/Tsinghua Univ.\/H.
