The supermassive pair lie closer together than any seen before ILLUSTRATION <\/figcaption><\/figure>\n\n

A pair of <\/strong>black holes have been discovered that are closer together than any pair previously observed in multiple wavelengths, a new report has revealed. They are in the heart of a galactic merger, UGC 4211, which has an active galactic nucleus, meaning its central black hole heats up the surrounding gas. When astronomers viewed the galaxy using the Atacama Large Millimeter\/ Submillimeter Array (ALMA), however, they found not one, but two black holes just 750 lightyears apart. The find led to an observing campaign using telescopes across the electromagnetic spectrum. <\/p>\n\n

\u201cEach wavelength [reveals] a different part of the story,\u201d says Ezequiel Treister from Universidad Cat\u00f3lica de Chile, who took part in the research. \u201cWhile ground-based optical imaging showed us the whole merging galaxy, Hubble showed us the nuclear regions at high resolutions. X-ray observations revealed that there was at least one active galactic nucleus in the system. All of these data together have given us a clearer picture of how galaxies such as our own turned out to be the way they are, and what they will become in the future.\u201d <\/span>www.almaobservatory.org<\/a><\/p>\n\n
