This is my current research, exploring the possibility of a circular polarization component in the CMB

Here is the cosmology talk describing the circular polarization physics and source soma_de_cp

The phase 2 of the talk is on detection prospects of the cosmic 21 cm signal when its confronted by the galactic synchrotron emission. In this talk, I show simulated synchrotron (polarized and unpolarized) signal. Polarized synchrotron signal leaks into the voltage measured and creates an obstruction to the cosmic 21 cm detection. The frequency space behavior of the cosmic signal is different from unpolarized synchrotron signal, but similar to its (synchrotron) polarized counterpart.
