Description

We present recent results on predictions of LISA's ability to determine cosmic string model parameters. These predictions are made using SGWBinner to fit an injected signal for a variety of cosmic string templates (to be discussed in a complementary talk). We find that LISA should be able to accurately and precisely recover the parameters of simple field-theoretic string models in standard cosmology, such as the string tension, over a wide range of values; we discuss regions of parameter-space where this recovery breaks down. We comment briefly on more complicated cosmological models, such as new degrees of freedom, and their impact on LISA's ability to reconstruct string backgrounds.
