A Search for the Pulsar Powering the High-Energy Emission in SNR MSH 11-62

The compositetype radio and Xray supernova remnant MSH 1162 contains a brightinner nebula with a Chandra resolved nonthermal Xray source at its center. Thenebula is coincident with a Fermi gammaray source. Together, the radio, Xray,and gammaray properties of this system lead to only one possible conclusion: ayoung (<20 kyr), highly energetic (>4E36 erg/s) pulsar powering a substantialwind nebula associated with the supernova remnant. An XMMNewton observationwould have an excellent chance of detecting the expected pulsations, criticalfor determining the energetics of the system, searching for gammaraypulsations, and modeling the interaction between the wind nebula and the thermalremnant. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
