Proposal Title: An Improved Single-Source Detector for the North American Nanohertz Obser-
vatory for Gravitational Waves
ABSTRACT:
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 eort to be the rst 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 ve of the
best-timed NANOGrav pulsars in an eort 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 in uencing the population of potential GW sources, such as merging
supermassive black-hole binary systems.
