Set upper limits on radio flux at multiple frequencies

Abstract

PSR J1907+0602 is a radio-faint, 107-ms GeV gamma-ray pulsar that was discovered with the Fermi LAT in a blind pulsar search. PSR J1907+0602 is located near the bright, extended TeV gamma-ray source MGRO J1908+06 which may be an associated pulsar wind nebula. We present an analysis of XMM-Newton X-ray data and EVLA radio data of the pulsar. We detect a faint X-ray source coincident with the gamma-ray pulsar and investigate its spectral and timing properties. We also find marginal evidence for a bow shock in the X-ray images. The pulsar was not detected with the EVLA, and we derive upper limits on the time-averaged radio flux in multiple frequency bands.
