The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is a collaboration of scientists and students that uses many radio pulsars as a type of Galactic-scale detector in an effort to be the first to directly detect gravitational waves (GWs). The current NANOGrav observing program is optimized for the detection of a stochastic background of GWs from unresolved sources in the Universe, but not robust for the detection of resolvable, individual GW sources. In this proposal, we request an increased observing cadence for five of the best-timed NANOGrav pulsars in an effort to boost our sensitivity to individual GW sources as shown in recent studies and simulations described in the accompanying text. These measurements will be crucial for understanding largely unconstrained astrophysical processes influencing the population of potential GW sources, such as merging supermassive black-hole binary systems.
