Flares in Blazars

2009
Blazars are active galactic nuclei characterized by strong, nearly pure non-thermal radiations; these extend across the electromagnetic spectrum, from radio frequencies to the most energetics γ rays observed, in some cases up to TeV energies.

Blazar periodico

2014
Un gruppo di ricerca di astrofisica italiano ha recentemente confermato una scoperta intrigante riguardo ad uno dei più noti e studiati blazar: l’oggetto denominato PKS2155-304. Tramite osservazioni ottenute con il telescopio INAF REM ed osservazioni ad alta energia ottenute con il satellite NASA Fermi, si è determinata l’esistenza di una periodicità ...
