Radio waves (blue in this composite image) trickle out of a cavity in hot X-ray emitting gas (purple) enveloping a massive galaxy (white, top).

In addition to Giacintucci, Markevitch, and Johnston-Hollitt, the authors are Daniel Wik (University of Utah), Qian Wang (University of Utah), and Tracy Clarke (Naval Research Laboratory). It is possible that the gas on the other side of the cluster from the cavity is less dense so the radio emission there faded more quickly.“As is often the case in astrophysics we really need multiwavelength observations to truly understand the physical processes at work,” said Melanie Johnston-Hollitt, a co-author from International Centre for Radio Astronomy in Australia.
The cavity is filled with radio emission from electrons accelerated to almost the speed of light – likely a result of the black hole’s feeding activity – providing evidence that an eruption of unprecedented size took place there.This extremely powerful eruption occurred in the Ophiuchus galaxy cluster, which is located about 390 million light-years from Earth. This record-breaking, gargantuan eruption came from a black hole in a distant galaxy cluster hundreds of millions of light-years away.“In some ways, this blast is similar to how the eruption of Mt. The black hole eruption that created the cavity released an amount of energy about five times greater than that involved in the most powerful event of this type known to date, observed in the galaxy cluster MS0735.6+7421. This Chandra image shows two vast cavities — each 600,000 light years in diameter — in the hot, X-ray emitting gas that pervades the galaxy cluster MS 0735.6+7421 (MS 0735 for short). hot gas. “the eruption is linked to powerful jets released by the supermassive black hole that sits at the core of the cluster’s central galaxy and actively feeds on the surrounding gas, occasionally blasting off large amounts of matter and energy.”So, the immense gravity of black holes capture everything, even light, yet at the same time produce jets and large amounts of matter and energy. We live under a solid firmament. But the team notes that this newfound eruption is thousands of times The acceleration likely originated from the supermassive black hole.“The radio data fit inside the X-rays like a hand in a glove,” said co-author Maxim Markevitch of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Researchers think that the source of the gigantic eruption is this black hole.Although black holes are famous for pulling material toward them, they often expel prodigious amounts of material and energy. In this study, the scientists combined the X-ray data with radio wave observations of the Ophiuchus cluster from the Murchison Widefield Array (MWA) in Australia and the Giant Metrewave Radio Telescope (GMRT) in India, revealing that the curved edge delimits a region filled with radio-emitting gas and is indeed part of the wall of a cavity in the hot gas.MS 0735+74 was the previous record-holder for the most powerful eruption discovered in the universe.

He has a Ph.D. in astronomy from the University of California, Los Angeles.© Society for Science & the Public 2000–2020. The team suggests that the electrons got revved up by a powerful outburst at least 240 million years prior from a supermassive black hole at the heart of the cluster’s central galaxy. The black hole eruption that created the cavity released an amount of energy about five times greater than that involved in the most powerful event of this type known to date, observed in the galaxy cluster MS0735.6+7421. This record-breaking, gargantuan eruption came from a black hole in a distant galaxy cluster hundreds of millions of light years away.“In some ways, this blast is similar to how the eruption of Mt. Their crucial advance was the use of new radio data from the MWA and data from the GMRT archives to show the curved edge is indeed part of the wall of a cavity, because it borders a region filled with radio emission.

If this gas shifted away from the galaxy it will have deprived the black hole of fuel for its growth, turning off the jets.This gas displacement is likely caused by “sloshing” of the gas around the middle of the cluster, like wine sloshing around in a glass.
