Fermi and Swift discovery of GeV gamma-ray and X-ray emission from the blazar PKS 2246+208
Abstract
The Large Area Telescope (LAT), one of two instruments on the Fermi Gamma-ray Space Telescope, has observed a flare in gamma rays from a source positionally consistent with the flat spectrum radio quasar PKS 2246+208 (also known as TXS 2246+208 and MG3 J224902+2106), with radio coordinates (J2000.0) R.A.: 342.252361 deg, Dec.: 21.11745 deg (Beasley et al. 2002, ApJS, 141, 13) and also listed in the CGRaBS, CRATES and 5BZ catalogs.
