Searching for anisotropic cosmic birefringence with polarization data from SPTpol
We present a search for anisotropic cosmic birefringence in 500  deg² of southern sky observed at 150 GHz with the SPTpol camera on the South Pole Telescope. We reconstruct a map of cosmic polarization rotation anisotropies using higher-order correlations between the observed cosmic microwave b...
