Testing Refracted Gravity with kinematics of galaxy clusters
Lorenzo Pizzuti, Federico Fantoccoli, Valeria Broccolato +2
Refracted Gravity (RG) is a a classical theory of gravity where a gravitational permittivity $ a monotonically-increasing function of the local density rho , is introduced in the P…
CHEX-MATE: Dynamical masses for a sample of 101 Planck Sunyaev-Zeldovich-selected galaxy clusters
Mauro Sereno, Sophie Maurogordato, Alberto Cappi +23
The Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at the Endpoint of structure formation (CHEX-MATE) is a programme to study a minimally biased sample…
On the nature of the missing mass of galaxy clusters in MOND: the view from gravitational lensing
Benoit Famaey, Lorenzo Pizzuti, Ippocratis D. Saltas
Modified Newtonian Dynamics (MOND) has long been known to fail in galaxy clusters, implying a residual missing mass problem for clusters in this context. Here, using mass profiles…
The radial orbits of ram-pressure-stripped galaxies in clusters from the GASP survey
A. Biviano, B. M. Poggianti, Y. Jaffé +4
We analyse a sample of 244 ram-pressure-stripped candidate galaxy members within the virial radius of 62 nearby clusters, to determine their velocity anisotropy profile . We…
Caustic and hydrostatic mass bias: Implications for modified gravity
Minahil Adil Butt, Balakrishna S. Haridasu, Yacer Boumechta +4
We propose and perform a joint analysis of the two different mass estimates of galaxy clusters, namely the hydrostatic and caustic techniques. Firstly, we show comprehensively that…
