Contribution to the 2026 Cosmology session of the 60th Rencontres de Moriond: Galactic moments: Understanding polarized foregrounds complexity in the quest for CMB primordial modes with LiteBIRD
S. Vinzl, J. Aumont, L. Vacher +4
Accurate modeling of polarized Galactic emission has become a major challenge for current and next-generation cosmic microwave background (CMB) -mode experiments. Ignoring the s…
Galactic Science with the LiteBIRD satellite: Spectral characterization of diffuse Galactic polarized emission at the angular power spectrum level
S. Vinzl, J. Aumont, L. Vacher +108
Detection of primordial -mode polarization in the cosmic microwave background (CMB) from tensor perturbations generated during inflation is a major scientific goal of future CMB…
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…
On the computational feasibility of Bayesian end-to-end analysis of LiteBIRD simulations within Cosmoglobe
R. Aurvik, M. Galloway, E. Gjerløw +107
We assess the computational feasibility of end-to-end Bayesian analysis of the JAXA-led LiteBIRD experiment by analysing simulated time ordered data (TOD) for a subset of detectors…
LiteBIRD science goals and forecasts: improved full-sky reconstruction of the gravitational lensing potential through the combination of Planck and LiteBIRD data
M. Ruiz-Granda, P. Diego-Palazuelos, C. Gimeno-Amo +102
Cosmic microwave background (CMB) photons are deflected by large-scale structure through gravitational lensing. This secondary effect introduces higher-order correlations in CMB an…
