  • Ashton, G.; Prix, R.; Jones, D.I. (College Park, MD : American Physical Society, 2018)
    Isolated nonaxisymmetric rotating neutron stars producing continuous-gravitational-wave signals may undergo occasional spin-up events known as glitches. If unmodeled by a search, these glitches can result in continuous ...
