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_{…
Nonlocal Teleparallel Cosmology
Sebastian Bahamonde, Salvatore Capozziello, Mir Faizal +1
Even though it is not possible to differentiate General Relativity from Teleparallel Gravity using classical experiments, it could be possible to discriminate between them by quant…
Observational constraints on dark matter-dark energy scattering cross section
Suresh Kumar, Rafael C. Nunes
In this letter, we report precise and robust observational constraints on dark matter-dark energy scattering cross section, using the latest data from cosmic microwave background (…
Effects of neutrino mass hierarchies on dynamical dark energy models
Weiqiang Yang, Rafael C. Nunes, Supriya Pan +1
We investigate how three different possibilities of neutrino mass hierarchies, namely normal, inverted, and degenerate, can affect the observational constraints on three well known…
Echo of interactions in the dark sector
Suresh Kumar, Rafael C. Nunes
We investigate the observational constraints on an interacting vacuum energy scenario with two different neutrino schemes (with and without a sterile neutrino) using the most recen…
A new interacting two fluid model and its consequences
German S. Sharov, Subhra Bhattacharya, Supriya Pan +2
In the background of a homogeneous and isotropic spacetime with zero spatial curvature, we consider interacting scenarios between two barotropic fluids, one is the pressureless dar…
Tsallis and Kaniadakis statistics from the viewpoint of entropic gravity formalism
Everton M. C. Abreu, Jorge Ananias Neto, Edesio M. Barboza +1
It has been shown in the literature that effective gravitational constants, which are derived from Verlinde's formalism, can be used to introduce the Tsallis and Kaniadakis statist…
