We all are now familiar with the Black holes also named as a supermassive hole, known to bolt up entire stars and launch streams of matter into space at almost the pace of light, due to their intense gravitational pull. A new study has, however, dispelled this long-believed notion.
The team of investigators from the University of Florida has issued a paper, in the journal Science, which shows the magnetic fields of black holes are not that powerful. Well, it turns out that the reality may not live up to the hype. That’s right! Scientists observed the black hole known as V404 Cygni, which is located approximately 8,000 light years from Earth and is nearly 40 miles in diameter. V404 Cygni had a different burst that was seized by the lens reflector of the Gran Telescopio Canarias in Canary Islands, Spain, back in 2015, and researchers used this information to estimate its magnetic field. They concluded that V404 Cygni’s magnetic energy was about 400 times less than experts had predicted. It’s an enormous discovery that could have innovating implications for our knowledge of black holes and physics itself.
Study co-author Stephen Eikenberry, said that the determinations would bring scientists closer to knowing how black holes’ magnetism works, expanding our knowledge of how matter behaves under the most severe conditions, an experience that could widen the limits of nuclear fusion power and GPS systems. These computations also will help investigators determine the half-century-old puzzle of how “jets” of particles moving at nearly the pace of light shoot out of black holes’ magnetic fields, while everything else is absorbed into their holes.
“The mystery is, how do you do that?” Eikenberry spoke. “Our surprisingly low computations will force new limitations on theoretical models that earlier focused on strong magnetic fields stimulating and directing the jet flows. We weren’t assuming this, so it changes much of what we imagined we identified.”
Research authors developed the analyses from data gathered in 2015 during a black hole’s rare outburst of jets. Smaller jet constructing black holes, like the one seen in the study, are the rock stars of galaxies. Their outbreaks occur quickly and are short-lived, said study lead author Yigit Dalilar and co-author Alan Garner, doctoral students in UF’s astronomy department. The 2015 explosions of V404 Cygni remained only a couple of weeks. The earlier time the same black hole had a similar incident was in 1989.
“To see it was something that occurs once or twice in one’s career,” Dalilar said. “This finding puts us one step closer to realising how the universe operates.”
The eruption from V404 Cygni was also inspected using X-ray investigations by California Institute of Technology and NASA’s NuSTAR space-based telescope, optical measurements from UltraCAM on the William Herschel telescope in the Canary Islands, and radio information from the Arcminute Microkelvin Imager telescope placed in the United Kingdom. The National Science Foundation and the University of Florida backed the study.
