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…
Status and future development of the COSMOCal Project for absolute CMB polarization calibration
Silvia Micheli, Alessia Ritacco, Alessandro Carones +36
The paper outlines the COSMOCal project, which will place an artificial polarized microwave source on a geostationary satellite to provide stable absolute calibration for CMB polar…
BROOM: a python package for model-independent analysis of microwave astronomical data
Alessandro Carones, Sijil Jose, Aliza Mustafa +2
We present BROOM, a new python package for the application of blind, minimum-variance component-separation techniques to microwave observations. The package enables the reconstruct…
Blind mitigation of foreground-induced biases on primordial modes for ground-based CMB experiments
Aliza Mustafa, Alessandro Carones, Nicoletta Krachmalnicoff +2
Observations of the Cosmic Microwave Background (CMB) B-mode polarisation provide a unique probe of inflationary physics. Extracting a reliable constraint on the tensor-to-scalar r…
Interpreting map-based / spectral properties of CMB foregrounds
Gilles Weymann-Despres, Léo Vacher, Léo Vacher +6
Map-space / decompositions of linear polarization are attractive for foreground and CMB analyses because they separate parity families: -family patterns directly contamina…
Is cosmic birefringence due to dark energy or dark matter? Simulation-based inference
Florie Carralot, Patricia Diego-Palazuelos, Adriaan J. Duivenvoorden +3
Simulation-based inference (SBI) is a powerful inference technique for cases where the exact functional form of the likelihood is not known. A prime example is the likelihood of cr…
