Dark Matter in Fractional Gravity III: Dwarf Galaxies Kinematics
F. Benetti, A. Lapi, G. Gandolfi +4
Recently we put forward a framework where the dark matter (DM) component within virialized halos is subject to a non-local interaction originated by fractional gravity (FG) effects…
Little Ado about Everything: CDM, a Cosmological Model with Fluctuation-driven Acceleration at Late Times
Andrea Lapi, Lumen Boco, Marcos M. Cueli +4
[abridged] We propose a model of the Universe (dubbed CDM) featuring a stochastic evolution of the cosmological quantities, that is meant to render small deviations from homogen…
Dark Matter in Fractional Gravity II: Tests in Galaxy Clusters
Francesco Benetti, Andrea Lapi, Giovanni Gandolfi +2
[abridged] Recently, in Benetti et al. (Astrophys. J. 2023, 949, 65), we suggested that the dark matter (DM) component in galaxies may originate fractional gravity. In such a frame…
Looking for Traces of Non-minimally Coupled Dark Matter in the X-COP Galaxy Clusters Sample
Giovanni Gandolfi, Balakrishna Sandeep Haridasu, Stefano Liberati +1
We look for possible evidence of a non-minimal coupling (NMC) between dark matter (DM) and gravity using data from the X-COP compilation of galaxy clusters. We consider a theoretic…
Methodological refinement of the submillimeter galaxy magnification bias. I. Cosmological analysis with a single redshift bin
Marcos M. Cueli, Joaquín González-Nuevo, Laura Bonavera +3
The main goal of this work, the second in a three-paper series, is to test the impact of a methodological improvement in measuring the magnification bias signal on a sample of subm…
Constraining Chameleon screening using galaxy cluster dynamics
Yacer Boumechta, Balakrishna S. Haridasu, Lorenzo Pizzuti +3
We constrain the Chameleon \textit{screening} mechanism in galaxy clusters, essentially obtaining limits on the coupling strength and the asymptotic value of the field $ϕ_{\inf…
