MELBOURNE, Australia--(BUSINESS WIRE)--May 31, 2023--

Scientists think they have found an explanation for what scientists thought was a “runaway” black hole speeding through the universe. Last month, scientists reported that they had seen what appeared to be an object unlike anything seen before. What originally appeared to be scratches on Hubble images was actually a black hole that had been thrown out from its home galaxy and was now speeding through the cosmos, scientists said. Astronomers had come to that conclusion after spotting a long trail of stars, formed 8 billion years ago. It was a stretched out, narrow shape, roughly the same size as our own Milky Way. Last month’s study suggested that those stars were the wake left behind from that runaway black hole. As the black hole travelled through a gas cloud, it left behind the right conditions to start forming stars, that study suggested. It was shock and a breakthrough for a number of reasons: it was unprecedented, and required a number of different conditions for it to be true. That led astronomers both to celebrate and question the theory, and in the time since other researchers have been working on their own ideas. Now scientists at the Instituto de Astrofísica de Canarias (IAC) have suggested their own, more ordinary explanation of the unusual, long star structure. They suggest that it is in fact just a flat or thin galaxy – one without a bulge that makes it wider – that is being seen from its side. “The motions, the size, and the quantity of stars fits what has been seen in galaxies within the local universe,” said Jorge Sanchez Almeida, an IAC researcher who is the first author of the article, in a statement. “It’s a relief to have found the solution to this mystery, the new proposed scenario is much simpler. In one sense it is also a pity, because the existence of fleeing black holes is expected, and this could have been the first one to be observed.” The team compared the mystery structure with another, much better known galaxy, named IC5249. That is near to us, has a similar mass of stars, and doesn’t have a galaxy either. They found that it was surprisingly similar. The stars were moving in similar ways to those found in closer, comparative galaxies, researchers said. That led scientists working on the new paper to suggest that it is a relatively normal and expected galaxy, rather than an out-of-control black hole. But they hope that further observations will shed further light on what exactly it is doing – and could still allow the galaxy to prove of interest to astronomers. “We also looked at the relation between the mass of the assumed galaxy and its maximum velocity of rotation, and discovered that indeed it is a galaxy which behaves like a galaxy,” said Ignacio Trujillo, an IAC researcher who worked on the study. “It is an interesting object, because it is quite a large galaxy at a very large distance from Earth, where the majority of the galaxies are smaller.” The proposal is reported in a paper, ‘Supermassive black hole wake or bulgeless edge-on galaxy?’, published in the journal Astronomy and Astrophysics.

Logan Paul vs Dillon Danis has been added to the KSI vs Tommy Fury fight card in October. YouTube star Paul has boxed before, drawing with KSI in an amateur bout and losing to his now-business partner in a professional contest, and the American has also taken on Floyd Mayweather in an exhibition fight. Now Paul, 28, will return to the boxing ring – having spent much of the last year in the wrestling ring with WWE – as he fights Danis on 14 October. Danis, 29, is an ex-teammate of UFC star Conor McGregor and has fought in MMA promotion Bellator. The American is best known as a jiu-jitsu practitioner, and he withdrew from a boxing match with KSI (real name Olajide Olatunji) in January. Upon Tuesday’s announcement of the upcoming fight at Manchester’s AO Arena, Paul said: “Almost two years after fighting the greatest boxer of all time, I am so pumped to return to the boxing ring. “Manchester, I hope you are ready for a night you will never forget, because The Prime Card is delivering in a big way, with KSI and I on either side of a double main event. “The world has seen the energy, athleticism and showmanship I’ve brought to WWE, but this October I plan on reminding everyone that I can bring it to boxing, too.” Paul and KSI launched the energy-drink company Prime together in 2022. Danis added: “I couldn’t care less what Logan Paul has done in the WWE, because when he is in the boxing ring, he is in a completely different world. It’s a world of pain, a world where he doesn’t have control, and it’s my world – not his. “On 14 October, in Manchester, Logan Paul is getting beat down.” Paul’s younger brother Jake, 26, has boxed more frequently than his sibling, compiling a 7-1 pro record. On Saturday, Jake Paul beat ex-UFC fighter Nate Diaz on points in Dallas. Click here to subscribe to The Independent’s Sport YouTube channel for all the latest sports videos.
