Forecasting synchrotron spectral parameters with QUIJOTE-MFI2 in combination with Planck and WMAP

Ana Almeida, José Alberto Rubiño-Martín, Roke Cepeda-Arroita +2

We present a parametric component separation forecast for the QUIJOTE-MFI2 instrument (10-20 GHz), assessing its impact on constraining polarised synchrotron emission at …

QUIJOTE scientific results XIX. New constraints on the synchrotron spectral index using a semi-blind component separation method

Debabrata Adak, J. A. Rubiño-Martín, R. T. Génova-Santos +13

We introduce a novel approach to estimate the spectral index, , of polarised synchrotron emission, combining the moment expansion of CMB and the constrained-ILC. We reconstruc…
