In recent years, thanks to the evolution of technology, a few more things about the Universe have been discovered, but specifically the distant Universe. An international scientific team recently captured the first example of an extremely bright and rapidly evolving astronomical event. distant universe.

This event, detected in the deep Universe, is similar, in terms of brightness, to a stellar explosion or superluminous supernova.

Deep Universe: Phenomenon may originate from a destroyed star

The research results were published in the Astrophysical Journal Letters, where this transient phenomenon is reported as bright as a stellar explosion or superluminous supernova, but with a much faster evolution.

According to the authors, this phenomenon may have originated in a star destroyed by a black hole, a supernova associated with a 'magnetar' or a pulsating supernova colliding with its 'circumstellar' matter.

The Conselho Superior de Pesquisa Científica (CSIC) of Spain said that these events are fast pulses with high energy in the blue or ultraviolet spectrum and with a spectacular visible brightness, which is decreasing.

The data obtained raise discussions about the origin of this and some other similar phenomena. The results of the work indicate that it is an active compact object: a black hole or a neutron star.

This model could explain the transient phenomenon AT 2018cow and it is possible that a similar PPISN model, with a different amount of 'circumstellar' matter, could also explain the light curve of MUSSES2020J.
