Title: An KPNO H(alpha) Search for Radio Pulsar Bow-Shock Nebula

Abstract: We propose a search for new H-alpha bow-shock pulsar wind nebulae (PWN) around known radio pulsars. While PWN produce flux from radio to gamma rays, only nine H-alpha bow-shock nebulae are currently known. The H-alpha emission probes the density fluctuation spectrum of the surrounding neutral hydrogen immediately preceding ionization, which can in turn characterize the environments of radio pulsars. For example, the Guitar Nebula produced by pulsar B2224+65 has constrained the Galaxy's turbulent fluctuation spectrum at the smallest spatial scales. We target ten radio pulsars that have not to date been imaged in H-alpha for bow-shock nebulae. The targets are a mix of young, canonical pulsars with strong pulsar winds, and old, millisecond pulsars (MSP). This proposal is nearly a resubmission of proposal 2017A-0411, but re- written for WIYN instead of Mayall. Both nights granted for 2017A-0411 were lost in July 2017 due to clouds and rain, and for 2018A we request the lost 2 nights for the targets not visible during our 2 nights in late October 2017.
