XMM-Newton Detects Mysterious X-Ray Oscillations in Supermassive Black Hole

Jan 14, 2025 by News Staff

In 2018, astronomers observed that the corona of 1ES 1927+654, an actively accreting, 1.4-million-solar-mass black hole located in a galaxy around 270...

This two-panel illustration shows a black hole surrounded by a disk of gas, before and after the disk is partially dispersed. In the left panel, the ball of white light above the black hole is the black hole corona, a collection of ultra-hot gas particles that forms as gas from the disk falls into the black hole. The streak of debris falling toward the disk is what remains of a star that was torn apart by the black hole’s gravity. The right panel shows the black hole after the debris from the star has dispersed some of the gas in the disk, causing the corona to disappear. Image credit: NASA / JPL-Caltech.
