Mapping the CMB with QUBIC spectral imaging
Alexandre Huchet, Tom Laclavère, Leonora Kardum
QUBIC, the Q & U Bolometric Interferometer for Cosmology, is a telescope that observes the polarisation of the sky in the millimetre-wavelength range. Its goal is to detect the pri…

Measuring cluster masses with Planck and SPT-SZ CMB lensing
Alexandre Huchet
Galaxy cluster masses help to constrain cosmological parameters through the halo mass function. To get rid of major biases in the mass measurement, we directly probe the cluster gr…

A measurement of cluster masses using Planck and SPT-SZ CMB lensing
Alexandre Huchet, Jean-Baptiste Melin
We used an unbiased CMB lensing mass estimator on 468 SPT-SZ clusters from the SPT-SZ and the Planck public data, the first such estimation using combined ground- and space-based d…
