A key indicator of a growing supermassive black hole – X-ray emission – has been found in an extremely distant galaxy. This galaxy, UHZ1, is 13.2 billion light-years away, seen when the universe was only 3% of its current age.

2025年1月13日 · Such “quasi-periodic oscillations” have only been observed in a handful of other supermassive black holes, where X-ray flashes appear with regular frequency. Radio images of 1ES 1927+654 reveal emerging structures that appear to be jets of plasma erupting from both sides of the galaxy’s central black hole following a strong radio flare ...

2023年11月6日 · By combining data from NASA’s Chandra X-ray Observatory and NASA’s James Webb Space Telescope, a team of researchers was able to find the telltale signature of a growing black hole just 470 million years after the big bang.

2021年7月28日 · Watching X-rays flung out into the universe by the supermassive black hole at the center of a galaxy 800 million light-years away, Stanford University astrophysicist Dan Wilkins noticed an intriguing pattern.

2024年10月23日 · Here we report that the canonical black hole low-mass X-ray binary (LMXB) V404 Cygni is part of a wide hierarchical triple with a tertiary companion at least 3,500 astronomical units (au)...

2022年5月2日 · This visualization shows 22 X-ray binaries in our Milky Way galaxy and its nearest neighbor, the Large Magellanic Cloud, that host confirmed stellar-mass black holes. The systems are shown at the same physical scale, and their orbital motion is sped up by nearly 22,000 times.

2025年1月13日 · The European Space Agency's XMM-Newton has detected rapidly fluctuating X-rays coming from the very edge of a supermassive black hole in the heart of a nearby galaxy. The results paint a fascinating picture that defies how we thought matter falls into such black holes, and points to a potential source of gravitational waves that ESA’s future mission, LISA, could see.

2025年1月14日 · Researchers capture giant black hole’s X-ray oscillations. Published on: 14 January 2025. An international research team, including Newcastle University’s Dr Adam Ingram, has detected rapidly fluctuating X-rays coming from the very edge of a supermassive black hole in a nearby galaxy.

2025年1月27日 · The bright white dots are black holes. The purple patches represent hot X-ray gas, and the neon pink veins represent filaments of warm gas. According to the model published in the study, jets from the black holes impact the hot X-ray gas. This gas cools into warm filaments, with some warm gas flowing back into the black hole.

6 天之前 · A team of top astronomers including Dr William Alston, Senior Lecturer in Data Science at the University of Hertfordshire’s Centre of Astrophysics, has detected unprecedented periodic X-ray pulses from the supermassive black hole 1ES 1927+654, located approximately 270 million light-years away. The pulses of X-ray light, initially observed at 18-minute intervals, have mysteriously accelerated.
