Detection of a powerful X-ray flare in NGC 1275
Scientists from the University of Michigan and their colleagues have recorded a powerful X-ray flare that occurred in the supermassive black hole at the center of the galaxy NGC 1275. This phenomenon began in February 2023 and became the most powerful of all recorded flares in this galaxy. 296 days after the initial X-ray flare, a burst of radio emission was detected, which became the subject of further investigation.
The researchers noted that the brightness of the object increased by approximately two times, and the double flare lasted less than two months. Archival data from NASA's Swift X-ray telescope, collected over nearly 20 years, were used to analyze the phenomenon. The hypothesis of star destruction by the black hole's gravity was dismissed due to the too slow fading of the emission. The most likely explanation for the observed phenomena was a sharp fluctuation in the rate of matter accretion or disturbances within the jet.
Impact on astronomical research
The scientific paper describing these results has been accepted for publication in the Astrophysical Journal Letters and has the DOI identifier 10.48550/arxiv.2608.13281. These discoveries could significantly impact our understanding of the processes occurring in supermassive black holes and their surroundings.
On September 2 at 19:37, the Hubble Space Telescope captured the active galaxy NGC 1275, highlighting the activity of this object in astronomical research. The photo was provided by the Institute of Astronomy at the University of Cambridge, United Kingdom.
These results underscore the importance of observations of supermassive black holes, as they may reveal new aspects of physical processes in such extreme conditions.
Further research using modern telescopes may provide additional information about the mechanisms that drive black hole activity and their impact on the surrounding environment. This, in turn, could contribute to a deeper understanding of galaxy evolution and star formation in the universe.
The recent findings regarding the powerful flare in NGC 1275 raise important questions about the efficiency of black holes in consuming matter. In a related study, researchers have concluded that black holes may be less effective at accreting material than previously believed. This insight could reshape our understanding of these cosmic giants and their behavior. To explore this intriguing perspective, read more about the implications of these findings here.
