Beyond dynamical dark energy: the role of dark sector interactions after DESI DR2
Weiqiang Yang, Sibo Zhang, Supriya Pan +2
Recent DESI DR2 observations have renewed interest in extensions of the CDM cosmological model, particularly through indications of a time-varying dark energy equation of state.…
Dark energy perturbations and the robustness of cosmological neutrino-mass constraints
Yu-Hang Yang, Emmanuel N. Saridakis, Yi-Fu Cai +1
Cosmological observations are placing increasingly stringent bounds on the sum of neutrino masses, approaching the lower limits implied by neutrino oscillation experiments. Recent…
Observational constraints on Luciano-Saridakis entropic cosmology
Matías Leizerovich, Susana J. Landau, Giuseppe Gaetano Luciano +2
A recently proposed generalized entropy by Luciano and Saridakis extends the standard Boltzmann-Gibbs and Bekenstein-Hawking framework through a microscopically motivated construct…
Highly suppressed tensor-to-scalar ratio from a modified Lennard-Jones inflationary potential
Panagiotis G. Stavros, Spyros Basilakos, Emmanuel N. Saridakis
The increasingly stringent observational bounds on primordial gravitational waves strongly constrain inflationary model building, favoring scenarios that predict highly suppressed…
A null test of the Hubble tension
Gerasimos Kouniatalis, Emmanuel N. Saridakis
The origin of the Hubble tension remains one of the central open problems in modern cosmology, with competing explanations invoking either early-Universe physics, late-time modific…
Ultra-fast growth of primordial black holes through radiative absorption
Dimitris S. Kallifatides, Theodoros Papanikolaou, Emmanuel N. Saridakis
We show that Schwarzschild primordial black holes (PBHs) formed in the radiation-dominated era can grow extremely rapidly through governed by the fu…
