The researchers had a black hole



Called AT2018cow, the object is called "Behia", and if there is a neutron star or a black hole – when two massive stars collapse, scientists understand what happens exactly in this type of event. "We know that black holes and neutron stars die a star," said Professor Raffaella Margutti, a North Korean teacher, in a statement, "but we have never seen them ever after." Margutti studied the bright Northwestern University event and presented her team at the American Astronomical Society meeting. Works will also be published Astrophysical Journal.

Initially, the researchers thought Cow Cow was a supernova, but it was 10-100 times brighter because of the typical supernova, scientists sought alternative explanations. Several observers also used the Cow to study X-rays, X-rays, radio waves and gamma rays. All of them got a wider look at The Cow.

And some lucky ones jumped. The Cowboys' nano galaxy in the cow is about two million light years away, which seems a lot, but astronomical standards are very close. In addition, less than the usual quantity of material in the event, which allowed astronomers to observe Cow Cow's "central engine".

Other researchers involved in the work accept the idea of ​​creating a black hole or a neutron star. However, the data suggest that Behia is the result of a black silk insert by inserting white dwarf.

While Cow Cow's clearness is exactly what he was, he saw in partnership that scientists might have more incidents in the future. "Cows are a kind of observation that is considered the most excellent example of astronomy: rapid response to transient events," said Keck Observatory, a statement by John O & # 39; Meara, the main scientist. "Looking forward, we are developing new instruments of observational politics and telescopes, in order to enable rapid and fast science in the sky as soon as possible."
