Cylindrical domain walls and gravitational waves - Einstein rosen wave emission from momentarily static initial configuration -

摘要

A self-gravitating cylindrical domain wall is considered as an example of non-spherical wall to clarify the interaction between a domain wall and gravitational waves. We consider the time evolution from a momentarily static initial configuration within an infinitesimal time interval using the metric junction formalism. We found that the wall with a large initial radius radiates large amplitude of the gravitational waves and under goes its large back reaction.
