Gravitational Radiation by Cosmic Strings in a Junction
نویسنده
چکیده
The formalism for computing the gravitational power radiation from excitations on cosmic strings forming a junction is presented and applied to the simple case of co-planar strings at a junction when the excitations are generated along one string leg. The effects of polarization of the excitations and of the back-reaction of the gravitational radiation on the small scale structure of the strings are studied.

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 non-periodically in time, and have cusps and kinks that interact with the junctions. We study the effect of junctions on the gravitational wave signal emanating from cosmic string cusps and kinks. We find that earlier results on the strength of individual bursts from cusps and...
متن کاملGravitational, Dilatonic and Axionic Radiative Damping of Cosmic Strings Typeset Using Revt E X 1
We study the radiation reaction on cosmic strings due to the emission of dila-tonic, gravitational and axionic waves. After discussing the renormalization of the string tension induced by time-symmetric self-interactions (thereby correcting errors in the literature), we concentrate on the nite radiation damping force associated with the half-retarded minus half-advanced \reactive" elds. We revi...

We study the radiation reaction on cosmic strings due to the emission of dilatonic, gravitational and axionic waves. After discussing the renormalization of the string tension induced by time-symmetric self-interactions (thereby correcting errors in the literature concerning the effect of the dilaton field), we concentrate on the finite radiation damping force associated with the halfretarded m...
متن کاملOn the gravitational, dilatonic and axionic radiative damping of cosmic strings
We study the radiation reaction on cosmic strings due to the emission of dilatonic, gravitational and axionic waves. After verifying the (on average) conservative nature of the time-symmetric self-interactions, we concentrate on the finite radiation damping force associated with the half-retarded minus half-advanced “reactive” fields. We revisit a recent proposal of using a “local back reaction...
متن کاملConstraints on Cosmic Strings from the LIGO-Virgo Gravitational Wave Detectors
Cosmic strings can give rise to a large variety of interesting astrophysical phenomena. Among them, powerful bursts of gravitational waves (GWs) produced by cusps are a promising observational signature. In this Letter we present a search for GWs from cosmic string cusps in data collected by the LIGO and Virgo gravitational wave detectors between 2005 and 2010, with over 625 days of live time. ...
