Results are presented from a semicoherent search for continuous gravitational waves from a nearby neutron star candidate, Fomalhaut b, using data collected in the second observing run of Advanced LIGO. The search is based on a hidden Markov model scheme, capable of tracking signal frequency evolution from the star's secular spin down and stochastic timing noise simultaneously. The scheme is combined with a frequency domain matched filter ($\mathcal{F}$-statistic), calculated coherently over…

Search for continuous gravitational waves from ten H.E.S.S. sources using a hidden Markov model
Isolated neutron stars are prime targets for continuous$-$wave (CW) searches by ground$-$based gravitational$-$wave interferometers. Results are presented from a CW search targeting ten pulsars. The
Application of a hierarchical MCMC follow-up to Advanced LIGO continuous gravitational-wave candidates
TLDR
All but five outliers are inconsistent with an astrophysical origin under the standard continuous wave signal model, and four are ascribed to instrumental artifacts and a strong hardware injection present in the data.
Einstein@Home All-sky Search for Continuous Gravitational Waves in LIGO O2 Public Data
We conduct an all-sky search for continuous gravitational waves in the LIGO O2 data from the Hanford and Livingston detectors. We search for nearly monochromatic signals with frequency 20.0 Hz ≤ f ≤
Geometric Approach to Analytic Marginalisation of the Likelihood Ratio for Continuous Gravitational Wave Searches
The likelihood ratio for a continuous gravitational wave signal is viewed geometrically as a function of the orientation of two vectors; one representing the optimal signal-to-noise ratio, the other
Validating continuous gravitational-wave candidates based on Doppler modulation

Status and perspectives of Continuous Gravitational Wave searches
: The birth of gravitational wave astronomy was triggered by the first detection of a signal produced by the merger of two compact objects (also known as a compact binary coalescence event). The
Empirically estimating the distribution of the loudest candidate from a gravitational-wave search
TLDR
This work introduces a new approach using extreme value theory to describe the distribution of the loudest template’s detection statistic in an arbitrary template bank, which automatically generalizes to a wider class of detection statistics, and improves the estimation of the expected maximum detection statistic at a negligible computing cost.
