To test this theory, astronomers from Japan, Mexico, Denmark, France, Italy and the US, looked at distant galaxies that are 9.5-12.5 billion lightyears away.
Supermassive black holes are difficult to detect because they do not emit any light, but can reveal their presence by interacting with their surroundings.
Washington: Astronomers have found the best evidence for a black hole of an elusive class known as “intermediate-mass” by using the combined power of two X-ray observatories and the keen vision of NASA’s Hubble Space Telescope. Weighing in at about 50,000 times the mass of our Sun, the black hole is smaller than the supermassive […]
New York: Astronomers have discovered 13 massive black holes in dwarf galaxies less than a billion light-years from the Earth, says a new study, adding that these dwarf galaxies, more than 100 times less massive than our own Milky Way, are among the smallest galaxies known to host massive black holes. According to the study, […]
Washington: Astronomers including one of Indian-origin have identified five pairs of supermassive black holes, each containing millions of times the mass of the Sun, in the centres of galaxies. The findings could help astronomers better understand how giant black holes grow and how they may produce the strongest gravitational wave signals in the universe. These […]
Washington: Scientists announced on Wednesday they have detected a fourth gravitational wave signal coming from the merger of two black holes. It’s the first time this phenomenon has been measured simultaneously by both the US-based LIGO and Italy-based Virgo detectors. Originally predicted in the early 20th century by Albert Einstein, gravitational waves — ripples in […]
Beijing: China on Thursday launched its first ever space telescope to observe black holes, pulsars and gamma-ray bursts. The 2.5-tonne Hard X-ray Modulation Telescope (HXMT) was launched via a Long March-4B rocket from Jiuquan Satellite Launch Centre in Gobi Desert at 11 a.m., reports Xinhua news agency. The HXMT, dubbed Insight, was sent into an […]
