Probing the properties of relic neutrinos using the cosmic microwave background, the Hubble Space Telescope and galaxy clusters
Rafael C. Nunes, Alexander Bonilla
We investigate the observational constraints on the cosmic neutrino background (CNB) given by the extended CDM scenario (CDM $+ N_{\rm eff} + \sum m_ν + c^2_{\rm eff} + c^2_{…
Accelerated cosmos in a non-extensive setup
H. Moradpour, Alexander Bonilla, Everton M. C. Abreu +1
Here, we consider a flat FRW universe whose its horizon entropy meets the Rényi entropy of non-extensive systems. In our model, the ordinary energy-momentum conservation law is not…
Constraints On Dark Energy Models From Galaxy Clusters and Gravitational Lensing Data
Alexander Bonilla, Jairo E. Castillo
The Sunyaev--Zel'dovich (SZ) effect is a global distortion of the Cosmic Microwave Background (CMB) spectrum as a result of its interaction with a hot electron plasma in the intrac…
Tsallis and Kaniadakis statistics from a point of view of the holographic equipartition law
Everton M. C. Abreu, Jorge Ananias Neto, Albert C. R. Mendes +1
In this work, we have illustrated the difference between both Tsallis and Kaniadakis entropies through cosmological models obtained from the formalism proposed by Padmanabhan, whic…
Holographic Dark Energy from Fluid/Gravity Duality Constraint by Cosmological Observations
Behnam Pourhassan, Alexander Bonilla, Mir Faizal +1
In this paper, we obtain a holographic model of dark energy using the fluid/gravity duality. This model will be dual to a higher dimensional Schwarzschild black hole, and we would…
