Proposal Type: General Category: Observation Category: Total Time Requested: Minimum Useful Time: Prop osal Title: ABSTRACT:
We propose a targeted search for radio pulsations from two candidate young pulsars identified in X-ray observations of the filled-center supernova remnants (SNRs) CTB 87 and G63.7+1.1. Images of the SNR fields with the Chandra X-ray telescope have revealed unresolved sources with properties suggestive of rotation-powered pulsars with active magnetospheres that are powering these nebulae. The candidate pulsar in CTB 87 lies within faint extended X-ray emission features reminiscent of the torus and jet structures seen around the Crab, Vela, and other young pulsars. To better constrain the ages, magnetic field strengths, energetics, and other properties essential to understanding the multiwavelength emissions of both the neutron star and SNR, we aim to detect radio pulsations from the central engines of these two remnants. Arecibo and the new PUPPI backend offer near-optimum capability to carry out these searches.
