Enhanced foreground mitigation in thermal SZ Compton- maps via polarization and deprojection
Jyothis Chandran, Mathieu Remazeilles, R. B. Barreiro
Residual foreground contamination in thermal Sunyaev-Zeldovich (SZ) Compton- parameter maps (-maps) arises mainly from Galactic emissions -- thermal dust and synchrotron radi…

An updated and improved thermal SZ -map from Planck PR4 data
Jyothis Chandran, Mathieu Remazeilles, R. B. Barreiro
In 2015, the Planck Collaboration released an all-sky map of the thermal Sunyaev-Zeldovich (SZ) effect, obtained by implementing the Needlet Internal Linear Combination (NILC) meth…

An improved Compton parameter map of thermal Sunyaev-Zeldovich effect from Planck PR4 data
Jyothis Chandran, Mathieu Remazeilles, R. B. Barreiro
Taking advantage of the reduced levels of noise and systematics in the data of the latest Planck release (PR4, also known as NPIPE), we construct a new all-sky Compton- paramete…
