Studying PSR J2229+6114: an Energetic Gamma-ray Emitting Young Pulsar

Abstract

PSR J2229+6114 is a recently discovered young and energetic gamma-ray-bright pulsar, one of only ~ 8 such objects known. High-resolution Chandra X-ray observations reveal remarkable structures within its pulsar wind nebula. Much remains to be understood in this system. In particular, we wish to: derive the absolute phase alignment between radio and X-ray pulses; measure the polarization characteristics of the pulsar to possibly infer its three-dimensional orientation to interpret the X-ray features; determine its radio spectrum; and maintain a phase-connected timing solution. To accomplish these objectives we request a total of 12 hr of GBT time at frequencies of 600, 800, 1400, and 2200 MHz, spread over a period of one year.
