First Search for r-mode Gravitational Waves from PSR J0537–6910
Liudmila Fesik, Maria Alessandra Papa
Abstract
Abstract We report results of the first search to date for continuous gravitational waves from unstable r-modes from the pulsar . We use data from the first two observing runs of the Advanced LIGO network. We find no significant signal candidate and set upper limits on the amplitude of gravitational-wave signals, which are within an order of magnitude of the spin-down values. We highlight the importance of having timing information at the time of the gravitational-wave observations, i.e., rotation frequency and frequency-derivative values, and glitch-occurrence times, such as those that a NICER campaign could provide.
