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…
The Three Hundred project: cosmic web identification from 2D gas and Compton- maps of galaxy clusters outskirts
Sara Santoni, Marco De Petris, Gustavo Yepes +4
Galaxy clusters are located at the nodes of the filamentary network known as the cosmic web. A more comprehensive understanding of galaxy clusters can be achieved by considering th…
A measurement of gas rotation in galaxy groups via the kinetic Sunyaev-Zeldovich effect
Tianyi Yang, Yan-Chuan Cai, Weiguang Cui +5
We utilise the kinetic Sunyaev-Zeldovich effect (kSZ) to measure the rotation of ionised gas within galaxy groups defined in the SDSS-DR7 galaxy sample, via their dipolar imprint o…
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: Modeling Baryon and Hot-Gas Fraction Evolution in Simulated Clusters
Elena Rasia, Roberta Tripodi, Stefano Borgani +8
The baryon fraction of galaxy clusters is a powerful tool to inform on the cosmological parameters while the hot-gas fraction provides indications on the physics of the intracluste…
Inference of morphology and dynamical state of nearby -SZ galaxy clusters with Zernike polynomials
Valentina Capalbo, Marco De Petris, Antonio Ferragamo +3
We analyse the maps of the Sunyaev-Zel'dovich (SZ) signal of local galaxy clusters () observed by the satellite in order to classify their dynamical state through m…
