On the residual missing mass of the Bullet Cluster
Benoit Famaey
Modified Newtonian Dynamics (MOND) is a paradigm that can do away with dark matter at galaxy scales, but displays a residual missing mass discrepancy in galaxy clusters. Prompted b…
Mass models of galaxy clusters from a non-parametric weak-lensing reconstruction
Tobias Mistele, Federico Lelli, Stacy McGaugh +2
We study the CLASH sample of galaxy clusters using a new deprojection method for weak gravitational lensing observations. This method is non-parametric, allowing us to infer mass p…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
A primordial origin to cosmic tensions: towards reconciling and with early dark energy and scale-dependent primordial non-Gaussianities
Clément Stahl, Vivian Poulin, Benoit Famaey +1
The Hubble () tension between direct measurements of the expansion rate and the prediction of the CDM cosmological model calibrated on the Cosmic Microwave Background (CMB)…
A cosmic degeneracy story: structure formation with warm dark matter and scale-dependent primordial non-Gaussianities
Clément Stahl, Benoit Famaey, Rodrigo Ibata +2
It has been recently shown that cosmological models with scale-dependent primordial non-Gaussianities (sPNG) could provide a possible path to solve current cosmic tensions. Moreove…
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…
