The birth of a relativistic jet following the disruption of a star by a cosmological black hole
A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet
fortuitously aligns with our line of sight, the overall brightness is Doppler boosted by several …

Minutes-duration optical flares with supernova luminosities
In recent years, certain luminous extragalactic optical transients have been observed to last
only a few days. Their short observed duration implies a different powering mechanism from …

Gamma-ray flares from relativistic magnetic reconnection in the jet of the quasar 3C 279
Spinning black holes in the centres of galaxies can release powerful magnetised jets. When
the jets are observed at angles of less than a few degrees to the line-of-sight, they are called …
