Observing peculiar gamma-ray pulsars with AGILE
Abstract
The AGILE gamma-ray satellite provides large sky exposure levels ( cm s per year on the Galactic Plane) with sensitivity peaking at 100 MeV where the bulk of pulsar energy output is typically released. Its 1 s absolute time tagging capability makes it perfectly suited for the study of gamma-ray pulsars. AGILE collected a large number of gamma-ray photons from EGRET pulsars (40,000 pulsed counts for Vela) in two years of observations unveiling new interesting features at sub-millisecond level in the pulsars' high-energy light-curves, gamma-ray emission from pulsar glitches and Pulsar Wind Nebulae. AGILE detected about 20 nearby and energetic pulsars with good confidence through timing and/or spatial analysis. Among the newcomers we find pulsars with very high rotational energy losses, such as the remarkable PSR B1509--58 with a magnetic field in excess of 10 Gauss, and PSR J2229+6114 providing a reliable identification for the previously unidentified EGRET source 3EG 2227+6122. Moreover, the powerful millisecond pulsar B1821--24, in the globular cluster M28, is detected during a fraction of the observations.
