The telescope at the International Space Station made an incredibly high resolution of x-ray measurements that arose as a result of a black hole that could have significant consequences for understanding these mysterious objects.
Scientists know that black holes transmit high-energy X-rays when they ingest the substance, but how and from where they were discussed. Neutron star research ISS or NICER has allowed scientists to observe these X-rays as never before. This observation can help scientists to better understand not only black holes, which are several times the mass of the Sun, as is the one we see here, but also huge beasts in galactic centers.
"It was discussed how black holes develop," said Gizmodo Erin Kara, a postdoctoral at the University of Maryland and NASA Goddard Space Flight Center. "We see them going to these crazy outbursts when they have a disc with material that falls in them … What is responsible for the outbreak is something they were discussing because black holes were discovered."
Black Holes are spatial branches that are both massive and compact, that at any given point, called the horizon of events, no substance or energy (including visible light) can escape its gravitational pull. However, when they suck the substance from a nearby companion star, they show a complex structure. The "acrecian disc" of the substance that is hardened by the black hole gravity runs around it like Saturn's rings, and the hot gas, called the corona, is sitting above the ring in the area of the black hole. These massive nutritional events are usually accompanied by explosions of high-energy x-rays from a corona that pass into lower-energy x-rays from the acrecion disc.
But how is the nutrition process progressing? Does the disk start more distant and then approach the horizon of events? Or is it a corona that moves inward while the disk stays close to the black hole?
Understanding this process required X-ray high-resolution measurements – not only that scientists should know the energy of X-rays, but also the exact time they arrived in a microsecond or less. Scientists end up looking for what they call "echoes of reverberation" or "light echoes". Light reflections are essentially high-energy X-rays from the corona, some of which have hit the acrecium disc, which causes X-rays with lower energy. Scientists are interested in measuring the time between the initial flash and the echoes of lower energy.
Scientists have spotted a black hole luminous echo with the name MAXI J1820 + 070 with NICER. The data showed that the gap was six to twenty times shorter than the previous measurements, according to data released today in Nature. This can be simply because NICER can measure timing with greater accuracy than other instruments.
"To measure these light reflections in half a millisecond is incredible," Kara said. Imagine – scientists could measure the time between X-rays and their echoes to a resolution of 300 nanoseconds for a black hole, distant 10,000 light-years away.
Scientists could change the measurement into a decision on the enlargement process. A shorter echo has shown that the acrecycle disc has reached much closer to the horizon of the event than previously thought, which means that the corona is smaller, not the acrecision disc that eventually moves closer.
"It's a cool measurement that tackles a lot of tension we've seen with slightly lower resolution measurements," said Daryl Haggard, PhD in Physics at McGill University, for Gizmodo.
But paper has its limitations. Haggard warned that this is just one source. "That could be the particular behavior of this acne black hole system," she said. "It's always a problem if you have a single source. We would like to see that the same behavior would be observed in the outbursts of other star massive black holes. "And there may be other explanations that match the data.
Nevertheless, the document could have significant consequences. This would solve the inconsistency between the largest supermassive black holes and these smaller black holes. Acrylic discs with supermassive black holes extend almost the entire path to a central black hole, and earlier measurements showed that smaller discs with black holes were not vague. New results show that they may only need better equipment.
This is a good observation and shows that at least one small black hole is more like supermassive black holes than previously thought. And it's cool that he came from a telescope at the International Space Station.
