We report results of an all-sky search for periodic gravitational waves with frequency between 50 and 510 Hz from isolated compact objects, e.g., neutron stars. A new hierarchical multistage approach is taken, supported by the computing power of the Einstein@Home project, allowing us to probe more deeply than ever before. 16 million subthreshold candidates from the initial search [LIGO Scientific and Virgo Collaborations, Phys. Rev. D 94, 102002 (2016)] are followed up in four stages. None of…

Improved post-processing in searches for continuous gravitational waves and a model for transient continuous gravitational wave emission from neutron star glitches
Gravitational waves (GW) are tiny oscillations in the fabric of space-time, first hypothesised within the framework of Einstein’s General theory of Relativity (GR) a little more than 100 years ago.
All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO O2 data
We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast spinning neutron stars with an asymmetry around their rotation axis, using data from
Search Methods for Continuous Gravitational-Wave Signals from Unknown Sources in the Advanced-Detector Era
Continuous gravitational waves are long-lasting forms of gravitational radiation produced by persistent quadrupolar variations of matter. Standard expected sources for ground-based interferometric
Comparison of methods for the detection of gravitational waves from unknown neutron stars
Rapidly rotating neutron stars are promising sources of continuous gravitational wave radiation for the LIGO and Virgo interferometers. The majority of neutron stars in our galaxy have not been
Characterizing the sensitivity of isolated continuous gravitational wave searches to binary orbits
TLDR
The sensitivity of CW searches to signals from sources in binary systems over an exhaustive range of binary orbits is investigated and Monte-Carlo simulations are used to constrain the ranges of binary orbital parameters that leave a CW signal from a source in a binary orbit visible in a search for signals from an isolated source.
