Abstract

We report the discovery and follow-up timing observations of two young energetic radio pulsars. PSR J1420-6048 has a period P = 68 ms and period derivative P = 83 × 10^-15, implying a characteristic age τ_c = 13 kyr and a surface dipole magnetic field strength B = 2.4 × 10¹² G. PSR J1837-0604 has P = 96 ms and Ṗ = 45 × 10^-15, implying τ_c = 34 kyr and B = 2.1 × 10¹² G. The two objects have large spin-down luminosities, and, on the basis of an empirical comparison of their properties with those of other young radio pulsars, they are expected to be observable as pulsed γ-ray sources. In fact, they lie within the error circles of γ-ray sources detected by the EGRET instrument on the Gamma Ray Observatory. We show that the pulsars are plausibly associated with the EGRET sources.
