Markarian 335, also known as the Moving Nebula, is a Seyfert galaxy containing a supermassive black hole, located 324 million light-years away in the constellation of Pegasus. The central black hole in this active galaxy nucleus is notable for its corona's spinning rate (at about 20 percent the speed of light) and its change in brightness from 2007 to 2014. The geometry of the corona has been deduced from relativistic blurring of the reflection of the accretion disc. An x-ray flare in 2013 is interpreted as an aborted jet.

  • La galassia Markarian 335 è una galassia nella costellazione di Pegaso, all'interno della quale vi è un buco nero supermassiccio. La galassia Markarian 335 chiamata anche MRK 335 è circa 324 milioni di anni luce da noi. Già dal 2007 gli studiosi osservavano un cambiamento di luminosità del buco nero supermassiccio al centro della galassia che ha iniziato a produrre lampi di luce a raggi X in sequenza. Su richiesta degli scienziati nel 2014 la missione NuSTAR ha registrato una fascio di luce a raggi X da due regioni vicine al buco nero supermassiccio al centro di Markarian 335. La forma della natura della corona non è ancora chiara, si pensa che i raggi X della corona fossero riflessi dal disco di accrescimento. Questo evento ha portato gli scienziati a pensare di aver osservato l'espulsione della corona in raggi X da un buco nero per la prima volta. (it)
