NuSTAR Sees Rare Blurring of Black Hole Light

NuSTAR observations reveal X-ray light streaming from regions near supermassive black hole Markarian 335. NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the black hole, called the corona, has moved closer to the […]

Our Universe May Have Emerged from a Black Hole in a Higher Dimensional Universe

New research from theoretical physicists at the Perimeter Institute proposes that our universe may have emerged from a black hole in a higher-dimensional universe. The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three Perimeter Institute researchers have […]

NuSTAR and XMM-Newton Observations of NGC 1365 Help Measure Black Hole Spin

Using observations from NuSTAR and XMM-NEWTON, a team of astronomers examined the time-varying spectral shape of highly excited iron atoms in the nucleus of the galaxy NGC 1365. The nuclei of most galaxies contain a massive black hole. In our Milky Way, for example, the nuclear black hole contains about four million solar masses of […]

Three Closely Orbiting Supermassive Black Holes Could Help Astronomers Search for Gravitational Waves

An international team of astronomers discovered three closely orbiting supermassive black holes that could help in the search for gravitational waves. An international team, including Oxford University scientists, led by Dr Roger Deane from the University of Cape Town, examined six systems thought to contain two supermassive black holes. The team found that one of […]
