QUIJOTE-TFGI polarization calibration -- Ground characterization and on-sky validation with Tau A and the Moon
Alessandro Fasano, Mateo Fernández-Torreiro, Guillermo Pascual-Cisneros +6
Our objective is to characterize the QUIJOTE Thirty and Forty GHz instrument (TFGI), calibrate it with a reference calibration signal on the ground, compare our results with on-sky…
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…
Spatial Variations of Polarized Synchrotron Emission in the QUIJOTE MFI Data using Neural Networks
J. M. Casas, L. Bonavera, J. González-Nuevo +7
Polarized synchrotron emission from ultra-relativistic electrons spiraling the Galactic magnetic field has become one of the most relevant emissions in the Interstellar medium thes…
Spectral Properties of Anomalous Microwave Emission in 144 Galactic Clouds
Roke Cepeda-Arroita, J. A. Rubiño-Martín, 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…
Optimization procedure of the baffle of the GroundBIRD Telescope to mitigate stray light
Miku Tsujii, Tomonaga Tanaka, Alessandro Fasano +10
We presented the optimization procedures of the baffle mounted on the GroundBIRD telescope for measuring the polarization of the Cosmic Microwave Background~(CMB). The telescope em…
GroundBIRD Telescope: Systematics Modelization of MKID Arrays Response
Yonggil Jo, Alessandro Fasano, Eunil Won +8
Kinetic inductance detectors are widely used in millimeter- and submillimeter-wave astronomy, benefiting from their fast response and relative ease of fabrication. The GroundBIRD t…
LiteBIRD Science Goals and Forecasts: constraining isotropic cosmic birefringence
E. de la Hoz, P. Diego-Palazuelos, J. Errard +112
Cosmic birefringence (CB) is the rotation of the photons' linear polarisation plane during propagation. Such an effect is a tracer of parity-violating extensions of standard electr…
