Searching for Cosmic Strings in New Observational Windows

Cosmic strings are predicted in many particle physics
models beyond the Standard Model. If Nature is described
by a theory admitting cosmic string solutions, then a
network of strings will form in the early universe and
survive to the present time. Strings leave behind
interesting signals in new observational windows such
as CMB polarization and 21cm redshift surveys. I will
discuss these signals and possible search strategies.
