Origin of the Sloshing Spiral in the Abell 2107 Galaxy Cluster

Muhammed Kıyami Erdim

We present a detailed thermodynamic analysis of a sloshing spiral discovered in the intracluster medium (ICM) of the galaxy cluster Abell 2107, based on deep Chandra X-ray Observat…

Modifying CDM dynamics via out-of-equilibrium axions: reconciling SH0ES and DESI values

Giovanni Montani, Luis A. Escamilla, Nakia Carlevaro +1

We investigate late-Universe dynamics in which the dark matter component is described by axion particles. The proposed framework departs from the standard CDM paradigm due to a…

Probing dynamical dark energy with late-time data: Evidence, tensions, and the limits of the CDM framework

Tengpeng Xu, Suresh Kumar, Yun Chen +4

We test the dynamical dark-energy CDM (CPL) framework against CDM using CMB anisotropies and lensing together with DESI DR2, SDSS-IV, transverse/angular BAO (BAOtr), and…

CDM cosmology from a type-II minimally modified gravity

Özgür Akarsu, Antonio De Felice, Eleonora Di Valentino +5

We integrate CDM, a promising scenario for alleviating cosmological tensions, into VCDM, a type-II minimally modified gravity. This promotes the scenario to a fully pre…

Revisiting the Matter Creation Process: Observational Constraints on Gravitationally Induced Dark Energy and the Hubble Tension

Tiziano Schiavone, Mariaveronica De Angelis, Luis A. Escamilla +2

The Hubble tension and the unknown origin of dark energy motivate the exploration of alternative mechanisms for late-time cosmic acceleration. We investigate gravitationally induce…

Nonlinear Matter Power Spectrum from relativistic -body Simulations: CDM versus CDM

Özgür Akarsu, Eleonora Di Valentino, Jiří Vyskočil +3

We present relativistic -body simulations of a CDM - sign-switching cosmological constant (CC) - scenario under general relativity and compare its nonlinear matter p…
