PITSZI: Probing Intra-cluster medium Turbulence with Sunyaev-Zel'dovich Imaging -- Application to the triple merging cluster MACS J0717.5+3745
R. Adam, T. Eynard-Machet, I. Bartalucci +8
Turbulent gas motions are expected to dominate the non-thermal energy budget of the intracluster medium (ICM). The measurement of pressure fluctuations from high angular resolution…
jaxspec : a fast and robust Python library for X-ray spectral fitting
Simon Dupourqué, Didier Barret, Camille M. Diez +2
Context. Inferring spectral parameters from X-ray data is one of the cornerstones of high-energy astrophysics, and is achieved using software stacks that have been developed over t…
CHEX-MATE : turbulence in the ICM from X-ray surface brightness fluctuations
Simon Dupourqué, Nicolas Clerc, Etienne Pointecouteau +15
The intra-cluster medium is prone to turbulent motion that will contribute to the non-thermal heating of the gas, complicating the use of galaxy clusters as cosmological probes. In…
Simulation-Based Inference with Neural Posterior Estimation applied to X-ray spectral fitting: Demonstration of working principles down to the Poisson regime
Didier Barret, Simon Dupourqué
Neural networks are being extensively used for modelling data, especially in the case where no likelihood can be formulated. Although in the case of X-ray spectral fitting, the lik…
