Description
We review GW helicity probes from LVK through LISA, PTA to CMB, and distill the kinematic projection of the three vectors consisting of two polarizations and their spatial separation, identifying the requirement of non co-linearity. LISA and PTA in their current form are thus not helicity sensitive. We present extensions that enable a measurement.
