Recent Observations of EGRET Pulsar Wind Nebulae

TL;DR

This paper reports recent multi-wavelength observations of pulsar wind nebulae associated with gamma-ray sources, revealing their X-ray and radio properties, and discussing new associations with TeV sources and specific nebulae.

Contribution

It provides new X-ray and radio data on pulsar wind nebulae linked to gamma-ray sources, including the discovery of a trail from PSR J1614-2230 and associations with HESS TeV sources.

Findings

X-ray extent of PWN associated with 3EG J1809-2328 observed.

Trail from millisecond pulsar PSR J1614-2230 detected.

Potential association of HESS TeV sources with specific PWN.

Abstract

We present recent X-ray and radio observations of pulsar wind nebulae discovered in EGRET error boxes. Two XMM-Newton observations show the X-ray extent of the rapidly moving PWN associated with the variable gamma-ray source 3EG J1809-2328, and a trail coming from the new millisecond pulsar PSR J1614-2230 at high Galactic z. We also briefly discuss three PWN that are HESS TeV sources including a new HESS source we argue is associated with the Eel nebula in 3EG J1826-1302.
