It was just a flash of light! New research has found an ultraluminous phenomenon which could be a massive star explosion caused by a Black Hole.
Scientists have discovered something unusually ultraluminous far in the depth of space. According to the latest findings of an international scientific team in Astrophysical Journal Letters, researchers have found an ultra-bright phenomenon in the universe that is likely from the explosion of a star sparked by a black hole. Moreover, researchers suggest that the transient bright phenomenon evolved much faster than a supernova, which is a powerful and luminous explosion of a star.
This new study also believes that there is a possibility that the ultra-bright phenomenon could also have originated from a pulsating supernova, which collided with its own circumstellar matter or with a supernova of a star with an extremely high magnetic field, known as a magnetar. This unusual discovery is part of an international project called Musses with the main objective to investigate the nature of moving phenomena or Ultra luminous Blue Transients in the Universe.

“There are several possibilities: that it is a star destroyed by the tidal effect of a massive black hole, or a supernova associated with a neutron star with a very strong magnetic field, or magnetar,” Pilar Ruiz Lapuente from the Institute of Fundamental Physics (IFF) in Spain explained about the findings. However, the research is specifically aimed to investigate a rapidly evolving transient phenomenon named MUSSES2020J, discovered on December 11, 2020. It is close to the center of a “normal” galaxy.
The researchers discovered that the phenomenon’s brightness surged significantly as they were observing it, which was comparable to another recent transient discovery known as AT 2018cow. The investigation’s findings suggest that the phenomenon is an active compact object, which experts believe to be either a black hole or a neutron star.
Lapuente further explained that this phenomenon could also be a case of pulsating supernova due to the instability emerged by PPSIN, which are the massive star explosions that collapse and form a new black hole while simultaneously throwing a jet-like stream of external layers. “A near-nuclear location of MUSSES2020J might imply a possible connection between the energy source of MUSSES2020J and the central part of the host galaxy,” the study mentioned.
