6. Retrieving EoR constraints from small-scale CMB data with an improved kSZ model

Marian Douspis (IAS)

In this talk, I will present the first constraints on the reionisation timeline obtained from a consistent analysis of small- and large-scale CMB data, namely SPT and Planck. Utilising random forests trained to reconstruct the kinetic and thermal Sunyaev Zel’dovich angular power spectra from a set of cosmological and reionisation parameters, according to the Salvati+2018 and Gorce+2020...

3. Galaxy clusters in the mm wavelengths: combine Planck and SPT

Laura Salvati (IAS, Paris Saclay)

Galaxy clusters are a powerful cosmological probe, being able to describe the latest evolution of large scale structure.
In recent years, cluster catalogs of thousands of objects have been detected in the mm wavelengths, through the thermal Sunyaev-Zeldovich effect. CMB experiments have therefore a fundamental role also in providing observables for the recent evolution of the Universe.
The...

5. Frequency dependence of the thermal dust E/B ratio and EB correlation: insights from the spin-moment expansion

The change of physical conditions across the turbulent and magnetized interstellar medium (ISM) induces a 3D spatial variation of the properties of Galactic polarized emission. The observed signal results from the averaging of different spectral energy distributions (SED) and polarization angles, along and between lines of sight. As a consequence, the total Stokes parameters Q and U will have...
