Description
We present results of gravitational backreaction applied to a realistic population of cosmic strings. Backreaction smooths strings and reduces the rate of energy loss, $\Gamma$. This smoothing does not give rise to strong cusps, with cusp-like behavior subdominant until at least modes $n\sim 10^6$. Backreaction generally causes strings to self-intersect, but the intersections typically involve only a small fraction of the loop's length; however, we discuss this as a mechanism to possibly unbind loops from galaxies. We close with a discussion of the impact of backreaction on the cosmic string gravitational wave background.
