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 a continuation of proposal 18A-0394, as 3 out of 4 nights were lost in July 2017 due to clouds and rain, and the majority of the 4th night. The target list is adjusted to include pulsars visible later in the year, as well as other recently discovered pulsar targets.
