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 possible detection 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…

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…

The Three Hundred Project hydrodynamical simulations: Hydrodynamical weak-lensing cluster mass biases and richnesses using different hydro models

Carlo Giocoli, Giulia Despali, Massimo Meneghetti +7

The mass of galaxy clusters estimated from weak-lensing observations is affected by projection effects, leading to a systematic underestimation compared to the true cluster mass, v…

The Three Hundred Project: The relationship between the shock and splashback radii of simulated galaxy clusters

M. Zhang, K. Walker, A. Sullivan +4

Observations of the intracluster medium (ICM) in the outskirts of galaxy clusters reveal shocks associated with gas accretion from the cosmic web. Previous work based on non-radiat…

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…

The Three Hundred project: Estimating the dependence of gas filaments on the mass of galaxy clusters

Sara Santoni, Marco De Petris, Gustavo Yepes +7

Galaxy clusters are located in the densest areas of the universe and are intricately connected to larger structures through the filamentary network of the Cosmic Web. In this scena…

Generating Galaxy Clusters Mass Density Maps from Mock Multiview Images via Deep Learning

Daniel de Andres, Weiguang Cui, Gustavo Yepes +5

Galaxy clusters are composed of dark matter, gas and stars. Their dark matter component, which amounts to around 80\% of the total mass, cannot be directly observed but traced by t…

The Three Hundred Project: Mapping The Matter Distribution in Galaxy Clusters Via Deep Learning from Multiview Simulated Observations

Daniel de Andres, Weiguang Cui, Gustavo Yepes +5

A galaxy cluster as the most massive gravitationally-bound object in the Universe, is dominated by Dark Matter, which unfortunately can only be investigated through its interaction…

The three hundred project: thermodynamical properties, shocks and gas dynamics in simulated galaxy cluster filaments and their surroundings

Agustín M. Rost, Sebastián E. Nuza, Federico Stasyszyn +8

Using cosmological simulations of galaxy cluster regions from The Three Hundred project we study the nature of gas in filaments feeding massive clusters. By stacking the diffuse ma…

Galaxy clusters morphology with Zernike polynomials: the first application on Compton parameter maps

Valentina Capalbo, Marco De Petris, Weiguang Cui +3

The study of the morphology of 2D projected maps of galaxy clusters is a suitable approach to infer, from real data, the dynamical state of those systems. We recently developed a n…
