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 ≤ 585.15 Hz and spin-down Hz s−1. We deploy the search on the Einstein@Home volunteer-computing project and follow-up the waveforms associated with the most significant results with eight further search stages, reaching the best sensitivity ever achieved by an all-sky survey up to 500 Hz. Six of the… 
Fourier transform of the continuous gravitational wave signal
The direct detection of continuous gravitational waves from pulsars is a much anticipated discovery in the emerging field of multi-messenger gravitational wave (GW) astronomy. Because putative pulsar
Modeling the Galactic Neutron Star Population for Use in Continuous Gravitational-wave Searches
Searches for continuous gravitational waves (GW) from unknown Galactic neutron stars provide limits on the shapes of neutron stars. A rotating neutron star will produce GW if asymmetric deformations
All-sky search for continuous gravitational waves from isolated neutron stars in the early O3 LIGO data
We report on an all-sky search for continuous gravitational waves in the frequency band 20–2000 Hz and with a frequency time derivative in the range of 1⁄2−1.0;þ0.1 × 10−8 Hz=s. Such a signal could
Density-clustering of continuous gravitational wave candidates from large surveys
The new clustering method presented in this paper is agnostic about the shape of the over-densities, is very effcient and it is capable of clustering two orders of magnitude more candidates than attainable before and, at fixed sensitivity it enables more than a factor of 30 faster follow-ups.
Search for continuous gravitational waves from 20 accreting millisecond x-ray pulsars in O3 LIGO data
Results are presented of searches for continuous gravitational waves from 20 accreting millisecond X-ray pulsars with accurately measured spin frequencies and orbital parameters, using data from the
Deep learning for clustering of continuous gravitational wave candidates II: identification of low-SNR candidates
A deep learning network is implemented that identifies clusters of signal candidates in the output of continuous gravitational wave searches and achieves a detection efficiency higher than 97% with a very low false alarm rate.
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
Performance of random template banks
This fraction is compared to the corresponding loss fraction for the best possible lattice-based template banks containing the same number of grid points and shows that in high dimensions, random template banks outperform the best known lattices.
Constraints on r-modes and Mountains on Millisecond Neutron Stars in Binary Systems
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
A frequency resolved atlas of the sky in continuous gravitational waves
We present the first atlas of the continuous gravitational wave sky, produced using LIGO O3a public data. For each 0.045 Hz frequency band and every point on the sky the atlas provides upper limits,


Results from the First All-Sky Search for Continuous Gravitational Waves from Small-Ellipticity Sources.
The search for continuous gravitational-wave signals with frequencies in the 500-1700 Hz range targeting neutron stars with ellipticity of 10^{-8} is presented, with double the sensitivity over any other result on the same data.
Search for continuous gravitational waves from Fomalhaut b in the second Advanced LIGO observing run with a hidden Markov model
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
Search for continuous gravitational waves: improving robustness versus instrumental artifacts
The standard multidetector F-statistic for continuous gravitational waves is susceptible to false alarms from instrumental artifacts, for example monochromatic sinusoidal disturbances (“lines”). This
Characterizing the continuous gravitational-wave signal from boson clouds around Galactic isolated black holes
Ultralight bosons can form large clouds around stellar-mass black holes via the superradiance instability. Through processes such as annihilation, these bosons can source continuous gravitational
The permanent ellipticity of the neutron star in PSR J1023+0038
A millisecond pulsar having an ellipticity, which is an asymmetric mass distribution around its spin-axis, could emit continuous gravitational waves, which have not been detected so far. An

This work presents a new method to remove non-Gaussian noise transients in gravitational wave data that preserves more data than previously achieved, while obtaining the same, when not higher, noise reduction.

On April 1st, 2019, the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO), joined by the Advanced Virgo detector, began the third observing run, a year-long dedicated search for
Triaxially deformed freely precessing neutron stars: continuous electromagnetic and gravitational radiation
The shape of a neutron star (NS) is closely linked to its internal structure and the equation of state of supranuclear matters. A rapidly rotating, asymmetric NS in the Milky Way undergoes free
