Abstract

Context. Pulsars PSR J0248+6021 (with a rotation period P = 217 ms and spin-down power Ė = 2.13 × 1035 erg s-1) and PSR J2240+5832 (P = 140 ms, Ė = 2.12 × 1035 erg s-1) were discovered in 1997 with the Nançay radio telescope during a northern Galactic plane survey, using the Navy-Berkeley Pulsar Processor (NBPP) filter bank. The GeV gamma-ray pulsations from both were discovered using the Fermi Large Area Telescope.
