Searching for New Pulsars for the North American Nanohertz Observatory for Gravitational Waves

Friday September 1, 2017
3:30 pm

 Presenter:  Kevin Stovall (NRAO)
 Series:  Physics and Astronomy Colloquium
 Abstract:  The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is an effort to detect gravitational waves at nanohertz frequencies using an array of millisecond pulsars (MSPs). I will describe the current status of NANOGrav and some of the ongoing efforts to increase the sensitivity of the timing array by finding new high-quality MSPs. There are multiple ongoing large area surveys to find new MSPs, including the Green Bank North Celestial Cap (GBNCC) pulsar survey, the Arecibo 327-MHz Drift Scan (AO327) survey, and the Pulsar Arecibo L-Band Feed Array (PALFA) survey. I will describe these pulsar surveys and highlight some of the interesting discoveries made so far, including NANOGrav MSPs, other interesting pulsars, and fast radio burst (FRB) results.
