The Three Hundred project: Low Gas Fraction Galaxy Clusters properties and their environment
Francesco Guidi, Marco De Petris, Sara Santoni +7
Galaxy cluster samples based on X-ray and Sunyaev-Zel'dovich (SZ) observations are affected by selection biases. These catalogs preferentially include systems with high gas content…

Comparing XRISM cluster velocity dispersions with predictions from cosmological simulations: are feedback models too ejective?
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +147
The dynamics of the intra-cluster medium (ICM), the hot plasma that fills galaxy clusters, are shaped by gravity-driven cluster mergers and feedback from supermassive black holes (…

The Three Hundred Project: A fast semi-analytic model emulator of hydrodynamical galaxy cluster simulations
Jonathan S. Gómez, Tomas Hough, Alejandro Jiménez Muñoz +3
Next-generation photometric and spectroscopic surveys will detect faint galaxies in massive clusters, advancing our understanding of galaxy formation in dense environments. Compari…
