Title: Gravitational Waves and Physics Frontiers with NANOGrav
Abstract: The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is a North American collaboration dedicated to monitoring over 70 millisecond pulsars using the Green Bank Telescope and Arecibo Observatory. These millisecond pulsars are precisely timed in order to detect perturbations created by nanohertz-frequency gravitational waves, which likely originate in supermassive black hole binary systems. We expect the sensitivity of the NANOGrav array to dramatically increase in the coming years due to millisecond pulsar discoveries, more sensitive instrumentation, improved detection algorithms, and international collaboration, increasing the possibility of a detection. In addition to the primary science goals of detecting and characterizing low-frequency gravitational waves, recent NANOGrav work has led to other interesting science results, such as tests of general relativity, neutron star physics, probing the interstellar medium, and galaxy evolution.
