Planck Constraints on Turbulence in the Coma Cluster

Baptiste Sigal, Etienne Pointecouteau, Nicolas Clerc +6

Turbulence within the intracluster medium (ICM) influences galaxy cluster thermodynamics and virialisation, contributing to non-thermal pressure support and impacting hydrostatic m…

CHEX-MATE: AMALGAM weak-lensing analysis of 41 Planck Sunyaev-Zel'dovich-selected galaxy clusters

Keiichi Umetsu, Raphael Gavazzi, Mauro Sereno +20

We present a weak-lensing shear analysis of 41 Planck SZ-selected galaxy clusters at from the CHEX-MATE sample, using wide-field Subaru/Suprime-Cam and CFHT/Meg…

Discriminating Planck Reionisation Histories with the kSZ Effect

M. Douspis, A. Gorce, S. Ilić +5

The epoch of reionisation is a key phase in cosmic history, but its detailed evolution remains poorly constrained by current cosmic microwave background (CMB) observations. We inve…

Ground calibration plan for the Athena/X-IFU microcalorimeter spectrometer

Alexeï Molin, François Pajot, Marc Audard +24

The X-ray Integral Field Unit is the X-ray imaging spectrometer on-board one of ESA's next large missions, Athena. Athena is set to investigate the theme of the Hot and Energetic U…

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: Are we getting cluster thermodynamics right?

R. Seppi, D. Eckert, E. Rasia +19

Galaxy clusters offer powerful insights into the large-scale structure of the Universe and the physics of baryons in hot state. Their scientific exploitation, however, hinges on ou…
