Implementation of the frequency-modulated sideband search method for gravitational waves from low mass X-ray binaries
Letizia Sammut, Christopher Messenger, Andrew Melatos +1
We describe the practical implementation of the sideband search, a search for periodic gravitational waves from neutron stars in binary systems. The orbital motion of the source in…
Tilted torus magnetic fields in neutron stars and their gravitational wave signatures
Paul D. Lasky, Andrew Melatos
Gravitational-wave diagnostics are developed for discriminating between varieties of mixed poloidal-toroidal magnetic fields in neutron stars, with particular emphasis on different…
Pulsar timing noise from superfluid turbulence
Andrew Melatos, Bennett Link
Shear-driven turbulence in the superfluid interior of a neutron star exerts a fluctuating torque on the rigid crust, causing the rotational phase to walk randomly. The phase fluctu…
Neutron star deformation due to multipolar magnetic fields
Alpha Mastrano, Paul D. Lasky, Andrew Melatos
Certain multi-wavelength observations of neutron stars, such as intermittent radio emissions from rotation-powered pulsars beyond the pair-cascade death line, the pulse profile of…
Stochastic gravitational wave background from hydrodynamic turbulence in differentially rotating neutron stars
Paul D. Lasky, Mark F. Bennett, Andrew Melatos
Hydrodynamic turbulence driven by crust-core differential rotation imposes a fundamental noise floor on gravitational wave observations of neutron stars. The gravitational wave emi…
Reanalysis of F-statistic gravitational-wave searches with the higher criticism statistic
M. F. Bennett, A. Melatos, A. Delaigle +1
We propose a new method of gravitational wave detection using a modified form of higher criticism, a statistical technique introduced by Donoho & Jin (2004). Higher criticism is de…
