Detecting primordial gravitational waves with circular polarization of the redshifted 21 cm line: II. Forecasts
Abhilash Mishra, Christopher M. Hirata
In the first paper of this series, we showed that the CMB quadrupole at high redshifts results in a small circular polarization of the emitted 21 cm radiation. In this paper we for…

Detecting primordial gravitational waves with circular polarization of the redshifted 21 cm line: I. Formalism
Christopher M. Hirata, Abhilash Mishra, Tejaswi Venumadhav
We propose a new method to measure the tensor-to-scalar ratio using the circular polarization of the 21 cm radiation from the pre-reionization epoch. Our method relies on the s…
