Prototypical active galaxy Arakelian 120 observed by Swift

(—Astronomers using NASA's Swift space observatory, have conducted a long-term monitoring campaign of a prototypical active galaxy, designated Arakelian 120 (Ark 120 for short). These observations reveal crucial information about the galaxy's variability, giving a hint about its true nature. The findings are presented in a paper published Oct. 13 on the arXiv pre-print server.
