Forecasting synchrotron spectral parameters with QUIJOTE-MFI2 in combination with Planck and WMAP
Ana Almeida, José Alberto Rubiño-MartÃn, 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 …

Spectral Properties of Anomalous Microwave Emission in 144 Galactic Clouds
Roke Cepeda-Arroita, J. A. Rubiño-MartÃn, R. T. Génova-Santos +23
Anomalous Microwave Emission (AME) is a diffuse microwave component thought to arise from spinning dust grains, yet remains poorly understood. We analyze AME in 144 Galactic clouds…

QUIJOTE scientific results XIX. New constraints on the synchrotron spectral index using a semi-blind component separation method
Debabrata Adak, J. A. Rubiño-MartÃn, 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 reconstru…
