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…

The SKA View of the Sunyaev-Zeldovich Effect from Massive Cosmic Halos
Yvette C. Perrott, Luca Di Mascolo, Rémi Adam +4
The thermal intracluster medium (ICM) can be observed via its interaction with Cosmic Microwave Background photons, known as the Sunyaev-Zeldovich (SZ) effect. This effect produces…

Multi-messenger constraints on transient accelerators of ultra-high energy cosmic rays
Antonio Condorelli, Jonathan Biteau, Olivier Deligny +1
The origin of ultra-high-energy cosmic rays (UHECRs) remains an open questions in astrophysics. We explore two primary scenarios for the distribution of UHECR sources, assuming tha…
