The astronomical spectacle caused by black holes disintegrating stars

Rare tidal disintegration events ( TDE) are processes that release energy when a star is torn apart by a mega-massive black hole.

The TED could provide an opportunity to study how mega-massive black holes grow by accumulating (or accreting) matter.

Yesterday, Nature and Nature Astronomy published a separate paper reporting observations of a rare tidal disintegration event.

These observations, from multiple telescopes in the optical and other wavelength bands, are consistent with the radiation produced by stars releasing bright jets as they violently disintegrate when they get too close to a supermassive black hole.

Although most detected TDEs originate in the nearby universe, this event came from a galaxy about 12.4 billion light-years away.

It can be seen on Earth because of its extraordinary brightness.

Furthermore, in the study published in Nature Astronomy, by simulating this event, the researchers suggest that the likely scenario at that time was that a star of about the same volume and mass as the Sun was disintegrated by a relatively low-mass black hole.

These two findings may enhance our understanding of the properties of black holes at cosmological distances.
