Continuous gravitational waves are nearly monochromatic signals emitted by asymmetries in rotating neutron stars. These signals have not yet been detected. Deep all-sky searches for continuous gravitational waves from isolated neutron stars require significant computational expense. Deep searches for neutron stars in binary systems are even more expensive, but these targets are potentially more promising emitters, especially in the hundreds of Hertz region, where ground-based gravitational-wave… 
Improved short-segment detection statistic for continuous gravitational waves
TLDR
This paper presents a new detection statistic that improves sensitivity by up to 19 % compared to the standard F -statistic for segments shorter than a few hours, which is important for all-sky searches.

Modelling neutron star mountains in relativity
Rapidly spinning, deformed neutron stars have long been considered potential gravitational-wave emitters. However, so far only upper limits on the size of the involved quadrupole deformations have
