Combining CMB datasets with consistent foreground modelling
M. Tristram, M. Douspis, A. Gorce +7
We present a joint cosmological analysis combining data from the Planck satellite, the Atacama Cosmology Telescope, and the South Pole Telescope. We construct a unified likelihood…

CHEX-MATE: towards a consistent universal pressure profile and cluster mass reconstruction
M. Muñoz-EcheverrÃa, E. Pointecouteau, G. W. Pratt +31
In a self-similar paradigm of structure formation, the thermal pressure of the hot intra-cluster gas follows a universal distribution once the profile of each cluster is normalised…

Reconstructing the epoch of reionisation with Planck PR4
S. IliÄ, M. Tristram, M. Douspis +8
The epoch of reionisation is a key phase in cosmic history, characterised by the ionisation of the intergalactic medium by the first luminous sources. In this work, we constrain th…
