Milky Way’s Supermassive Black Hole Flares Irregularly and Unpredictably, Astronomers Find astronomy space science
, the 4.3-million-solar-mass black hole at the center of our Milky Way Galaxy, is a strong source of radio, X-rays and gamma rays. It also displays flaring emission in the X-ray band atop a steady, quiescent level, as well as in other wavebands, most prominently in the near-infrared. The physical process producing the flares is not fully understood and it is unclear if the flaring rate varies, although some recent works suggest it has reached unprecedented variability in recent years.
Apart from a handful of interruptions and Sun constraints, Swift/XRT has pointed at the Galactic center every 1-3 days since 2006. After 2012, the frequency of flares increased again — the researchers had a difficult time distinguishing a pattern. “I’ve been applying for more observing time regularly. It’s a very special observing program that allows us to conduct a lot of research.”
