Surface Density of Disk Galaxies in MOND
Antonino Del Popolo, Morgan Le Delliou
In this paper, we extend a paper by Milgrom (2009, MNRAS 398, 1023) dealing with the existence of a quasi-universal surface density for object of all mass and structure, if they ar…
Fuzzy dark matter soliton as gravitational lens
Ke Wang, M. Le Delliou
The Schrödinger-Poisson (SP) equations predict fuzzy dark matter (FDM) solitons. Given the FDM mass , the FDM soliton in the Milky Way is massive $\sim 1…
Matching collapse and expansion across Matter Trapping surfaces in inhomogeneous CDM models
Alan Maciel, M. Le Delliou, José P. Mimoso
In the present work we examine the MTS, for the restriction to spherical dust plus , proving that it actually is a characteristic surface of the Cauchy problem (generated by it…
Emergence of Dark Energy from topology and chiral spinors
J. Lorca Espiro, Yerko Vásquez, M. Le Delliou
Under the existence of a massless spinor with respect to the total connection in a spacetime modeled as a Lorentzian manifold with internal boundaries, such as finite volume semi-c…
Hubble tension in an anisotropic Universe
Maksym Deliyergiyev, Morgan Le Delliou, Antonino Del Popolo
We explore the Hubble tension within an anisotropic cosmological framework by revisiting the Bianchi type-I model introduced in Le Delliou et al. 2020. Motivated by ongoing debates…
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.…
