Recently Discovered Pulsars and Unidentified Egret Sources

We present a correlative study between all unidentified EGRET sources at low Galactic latitudes and the newly discovered pulsars in the released portion of the Parkes multibeam radio survey. We note 14 positional coincidences: eight of these are “Vela-like” pulsars, with relatively small periods, small characteristic ages, and high spin-down luminosities. Three of these coincidences have been investigated by D’Amico et al. (2001) and Camilo et al. (2001). Among the others, we argue that PSR J1015−5719 may plausibly generate part of the high energy radiation observed from 3EG J1014−5705. Three additional interesting cases are: 3EG J1410−6147 and either of PSRs J1412−6145 or J1413−6141, if the pulsars are at the estimated distance of the coincident SNR G312.4−0.4; and 3EG J1639−4702/PSR J1637−4642. The remaining positional coincidences between the EGRET sources and the newly discovered pulsars are almost certainly spurious. Subject headings: pulsars: general — pulsars: individual (PSR J1015−5719, PSR J1412−6145, PSR J1413−6141, PSR J1637−4642) — gamma rays: observations
