Astronomers have never seen a pair of black holes quite like this one — but the universe may be filled with them. astronomy.com/science/a-gala…

It’s all wibbly-wobbly star material. Scientists have used our NICER telescope to observe the wobbly leftovers of a black hole’s snack. By watching how the wobble changed over time, they determined how fast the black hole was spinning. Learn more: news.mit.edu/2024/using-wob…

It has long been predicted that after the supermassive black hole disrupts a star, the newly formed accretion disc should precess. Finally, we have detected it!!! Read our results in the "fresh from the oven" Nature article: nature.com/articles/s4158…

An international team of researchers discovered signs of an intermediate-mass black hole in the star cluster IRS 13, near the supermassive black hole Sagittarius A* at the center of our galaxy. Observations from various telescopes, including ALMA Observatory📡 and Chandra Observatory suggest

Some certificates just mean more than others - I am really honored that I could have presented our results during the 80th anniversary of the Main Astronomical Observatory in Kyiv, Ukraine #kyiv #ukraine #astronomy

The detection of a binary star system close to the supermassive black hole in the center of Milky Way is shared in Nature Communications. This provides insights about dynamics & evolution of stars in vicinity of our Galaxy’s supermassive black hole, Sagittarius A*: nature.com/articles/s4146…

A paper in Nature Communications reports the detection of a binary star system close to the supermassive black hole in the center of the Milky Way. Such systems have been predicted but have previously eluded detection. go.nature.com/3ZTRNm9
