Cusps of cosmic strings emit strong beams of high-frequency gravitational waves (GW). As a consequence of these beams, the stochastic ensemble of gravitational waves generated by a cosmological network of oscillating loops is strongly non-Gaussian, and includes occasional sharp bursts that stand above the rms GW background. These bursts might be detectable by the planned GW detectors LIGO/VIRGO and LISA for string tensions as small as G&mgr; approximately 10(-13). The GW bursts discussed here…

Gravitational Wave Bursts as Harbingers of Cosmic Strings Diluted by Inflation.
TLDR
It is demonstrated that a network of cosmic strings diluted by inflation can regrow to a level that is potentially observable today in gravitational waves (GWs) within the sensitivity reach of current and future GW observatories.
Stochastic gravitational wave background from smoothed cosmic string loops
We do a complete calculation of the stochastic gravitational wave background to be expected from cosmic strings. We start from a population of string loops taken from simulations, smooth these by
Gravitational radiation from cosmic (super)strings: Bursts, stochastic background, and observational windows
The gravitational wave (GW) signals emitted by a network of cosmic strings are reexamined in view of the possible formation of a network of cosmic superstrings at the end of brane inflation. The
Gravitational waves from light cosmic strings: Backgrounds and bursts with large loops
The mean spectrum and burst statistics of gravitational waves produced by a cosmological population of cosmic string loops are estimated using analytic approximations, calibrated with earlier
Gravitational-wave stochastic background from kinks and cusps on cosmic strings
We compute the contribution of kinks on cosmic string loops to stochastic background of gravitational waves (SBGW). We find that kinks contribute at the same order as cusps to the SBGW. We discuss
Forecast constraints on cosmic string parameters from gravitational wave direct detection experiments
Gravitational waves (GWs) are one of the key signatures of cosmic strings. If GWs from cosmic strings are detected in future experiments, not only their existence can be confirmed but also their
Gravitational wave bursts from cosmic superstrings with Y-junctions
Cosmic superstring loops generically contain strings of different tensions that meet at Y-junctions. These loops evolve nonperiodically in time, and have cusps and kinks that interact with the
Cosmic strings as emitters of extremely high energy neutrinos
We study massive particle radiation from cosmic string kinks, and its observability in extremely high energy neutrinos. In particular, we consider the emission of moduli --- weakly coupled scalar
Implications of fast radio bursts for superconducting cosmic strings
Highly beamed, short-duration electromagnetic bursts could be produced by superconducting cosmic string (SCS) loops oscillating in cosmic magnetic fields. We demonstrated that the basic
