Spectral Imaging with QUBIC: building frequency maps from Time-Ordered-Data using Bolometric Interferometry
M. Regnier, T. Laclavère, J-Ch. Hamilton +34
The search for relics from the inflation era in the form of B-mode polarization of the CMB is a major challenge in cosmology. The main obstacle appears to come from the complexity…
Tensions in cosmology: a discussion of statistical tools to determine inconsistencies
MatÃas Leizerovich, Susana J. Landau, Claudia G. Scóccola
We present a comprehensive analysis of statistical tools for evaluating tensions in cosmological parameter estimates arising from distinct datasets. Focusing on the unresolved Hubb…
Faster Bayesian inference with neural network bundles and new results for models
Augusto T. Chantada, Susana J. Landau, Pavlos Protopapas +2
In the last few years, there has been significant progress in the development of machine learning methods tailored to astrophysics and cosmology. We have recently applied one of th…
Enhancing CMB map reconstruction and power spectrum estimation with convolutional neural networks
Belén Costanza, Claudia G. Scóccola, MatÃas Zaldarriaga
The accurate reconstruction of Cosmic Microwave Background (CMB) maps and the measurement of its power spectrum are crucial for studying the early universe. In this paper, we imple…
