DAMPE detection of GeV gamma-ray flare from FSRQ S4 1800+44
Abstract
The DArk Matter Particle Explorer (DAMPE) as a high energy cosmic ray and gamma-ray satellite-borne observatory, has detected GeV gamma-ray flare from a source positionally coincident with the flat spectrum radio quasar(FSRQ) S4 1800+44 with redshift of z=0.663 (Walsh & Carswell, 1982, MNRAS, 200, 191) and coordinates (J2000.0) of R.A.: 270.3846454 deg, Dec.: 44.0727500 deg (Johnston et al. 1995, AJ, 110, 880).
