An image of the central region of the spiral galaxy NGC 4151 which is home to a supermassive black hole.is in full swing at this point, and to celebrate, NASA has released stunning observations of the heart of a distant spiral galaxy — as well as the monster supermassive black hole that dwells in that heart.led by the Japan Aerospace Exploration Agency with contributions from NASA; they show the center of spiral galaxy NGC 4151.
Additionally, matter that doesn't fall into the maw of the monster black hole can get channeled toward the object's poles by powerful magnetic fields that accelerate these particles to near-light speeds, blasting them out as, one from each pole. This situation is accompanied by a burst of electromagnetic radiation that, when combined with emissions from the accretion disk, often makes an AGN brighter than the combined light of every star in the galaxy around it.
Scientists have theorized that the majority of the power of AGNs manifest through X-rays that originate from regions of hot and flaring matter embedded in the accretion disk close to their central black hole. When these X-rays are reflected off the cooler and denser regions of the same swirling cloud of matter, they're believed to cause iron in those regions to flare — indeed accounting for this discovery. An X-ray peak at around 6.
Though this specific result from XRISM focuses on iron, that is by no means the only element the X-ray telescope is able to distinguish. The satellite can also detect the elements sulfur, calcium, argon and others in AGNs depending on the source.
