Where do X-ray low surface brightness clusters sit with respect to filaments?

S. Zarattini, S. Andreon, E. Puddu

The aim of this work is to study the position of gas-rich and gas-poor galaxy clusters within the large-scale structure and, in particular, their distance to filaments. Our sample…

Euclid: Field-level inference of primordial non-Gaussianity and cosmic initial conditions

A. Andrews, J. Jasche, G. Lavaux +147

A primary target of the \Euclid space mission is to constrain early-universe physics by searching for deviations from a primordial Gaussian random field. A significant detection of…

Euclid preparation: TBD. The impact of line-of-sight projections on the covariance between galaxy cluster multi-wavelength observable properties -- insights from hydrodynamic simulations

Euclid Collaboration, A. Ragagnin, A. Saro +240

Cluster cosmology can benefit from combining multi-wavelength studies, which can benefit from characterising the correlation coefficients between different mass-observable relation…

Non-thermal emission in galaxy groups at extremely low frequency: the case of A1213

T. Pasini, V. H. Mahatma, M. Brienza +7

Galaxy clusters and groups are the last link in the chain of hierarchical structure formation. Their environments can be significantly affected by outbursts from AGN, especially in…

Gas thermodynamics meets galaxy kinematics: Joint mass measurements for eROSITA galaxy clusters

Pengfei Li, Ang Liu, Matthias Kluge +13

The mass of galaxy clusters is a critical quantity for probing cluster cosmology and testing theories of gravity, but its measurement could be biased given assumptions are inevitab…

Cosmography from accurate mass modeling of the lens group SDSS J0100+1818: five sources at three different redshifts

A. Bolamperti, C. Grillo, G. B. Caminha +6

Systems where multiple sources at different redshifts are strongly lensed by the same deflector allow one to directly investigate the evolution of the angular diameter distances wi…
