We explore the possibility of very long-lived gravitational-wave transients (and detector artifacts) lasting hours to weeks. Such very long signals are both interesting in their own right and as a potential source of systematic error in searches for persistent signals, e.g., from a stochastic gravitational-wave background. We review possible mechanisms for emission on these time scales and discuss computational challenges associated with their detection: namely, the substantial volume of data…

Long-duration transient gravitational-wave search pipeline
A new data analysis pipeline is presented to search for un-modeled long-lived transient gravitational-wave signals with duration between 10− 10 s, based on an excess cross-power statistic in a network of detectors, generalized to an arbitrary number of detectors.
Search strategies for long gravitational-wave transients: Hidden Markov model tracking and seedless clustering
It is demonstrated that the hidden Markov model tracking is a good option in model-agnostic searches for low signal-to-noise ratio signals, and it is shown that it can outperform the seedless method for certain categories of signals while also being computationally more efficient.
All-sky search for long-duration gravitational wave transients with initial LIGO
We present the results of a search for long-duration gravitational wave transients in two sets of data collected by the LIGO Hanford and LIGO Livingston detectors between November 5, 2005 and
Distinguishing transient signals and instrumental disturbances in semi-coherent searches for continuous gravitational waves with line-robust statistics
Non-axisymmetries in rotating neutron stars emit quasi-monochromatic gravitational waves. These long-duration 'continuous wave' signals are among the main search targets of ground-based
Cross-correlation method for intermediate duration gravitational wave searches associated with gamma-ray bursts
Several models of gamma-ray burst progenitors suggest that the gamma-ray event may be followed by gravitational wave signals of $10^3$-$10^4$ seconds duration (possibly accompanying the so-called
All-sky radiometer for narrowband gravitational waves using folded data
We demonstrate an all-sky search for persistent, narrowband gravitational waves using mock data. The search employs radiometry to sidereal-folded data in order to uncover persistent sources of
Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO and Advanced Virgo
A possible observing scenario for the Advanced LIGO and Advanced Virgo gravitational-wave detectors over the next decade is presented, and the expected sensitivity of the network to transient gravitational- wave signals is determined, and its capability to determine the sky location of the source is studied.
Prospects for observing and localizing gravitational-wave transients with Advanced LIGO, Advanced Virgo and KAGRA
The sensitivity of the LIGO network to transient gravitational-wave signals is estimated, and the capability of the network to determine the sky location of the source is studied, to facilitate planning for multi-messenger astronomy with gravitational waves.
How effective is machine learning to detect long transient gravitational waves from neutron stars in a real search?
It is determined that CNNs are robust towards signal morphologies that differ from the training set, and they do not require many training injections/data to guarantee good detection efficiency and low false alarm probability.
Multi-waveform cross-correlation search method for intermediate-duration gravitational waves from gamma-ray bursts
Gamma-ray Bursts (GRBs) are flashes of γ-rays thought to originate from rare forms of massive star collapse (long GRBs), or from mergers of compact binaries (short GRBs) containing at least one
