Enhanced foreground mitigation in thermal SZ Compton-$y$ maps via polarization and deprojection

Jyothis Chandran, Mathieu Remazeilles, R. B. Barreiro

Residual foreground contamination in thermal Sunyaev-Zeldovich (SZ) Compton-$y$ parameter maps ($y$-maps) arises mainly from Galactic emissions -- thermal dust and synchrotron radi…
