Abstract

The Continuous Waves (CW) Search Group of the LIGO Scientific Collaboration and Virgo Collaboration carries out a diverse suite of searches for a diverse set of possible CW sources. Assumptions underlying these searches will be discussed, along with strategies used so far to keep our eyes wide open while also giving due attention to the most promising sources. One important assumption to date has been that fast-spinning, non-axisymmetric neutron stars are the most promising class of CW sources. If the most promising source class is, instead, black hole super-radiance from axion clouds, then current searches may not be optimal. Potential modifications to current all-sky searches to address super-radiance will be discussed.
