Cosmic strings and strings in gravitational waves
We consider strings with the Nambu action as extremal surfaces in a given space-time, thus, we ignore their back reaction. Especially, we look for strings sharing one symmetry with the underlying space-time. If this is a non-null symmetry, the problem of determining the motion of the string can be dimensionally reduced. We get exact solutions for the following cases: straight and circle-like st...
متن کاملGravitational Waves from Cosmic Strings
Gravitational waves from cosmic strings are generated in the first fractions of a second after the Big Bang, potentially providing a unprecedented probe of the early universe. We discuss the key dynamical processes underlying calculations of the stochastic background produced by a string network and we detail the parameter dependencies of the resulting spectral density Ωgr(f). The present const...
متن کاملGravitational Waves and Light Cosmic Strings
Gravitational wave signatures from cosmic strings are analyzed numerically. Cosmic string networks form during phase transistions in the early universe and these networks of long cosmic strings break into loops that radiate energy in the form of gravitational waves until they decay. The gravitational waves come in the form of harmonic modes from individual string loops, a “confusion noise” from...
متن کاملGravitational waves, black holes and cosmic strings in cylindrical symmetry
The emission of gravitational waves by black holes is under intense investigation, in preparation for the expected observational study of black holes and other astrophysical objects by upcoming gravitational-wave detectors. Most of this work is either numerical or in an approximation, since we lack a full physical understanding of the dynamics of black holes and gravitational waves. The accepte...
متن کاملGravitational phase operator and cosmic strings.
A quantum equivalence principle is formulated by means of a gravitational phase operator which is an element of the Poincare group. This is applied to the spinning cosmic string which suggests that it may contain gravitational torsion. A new exact solution of the EinsteinCartan-Sciama-Kibble equations for the gravitational field with torsion is obtained everywhere for a cosmic string with unifo...
