Fractional holographic dark energy

open access: yesPhysics Letters B
Holographic dark energy theories present a fascinating interface to probe late-time cosmology, as guided by contemporary ideas about quantum gravity. In this work, we present a new holographic dark energy scenario designated “Fractional Holographic Dark ...

On oscillating dark energy

open access: yesAstroparticle Physics, 2006
Distance-redshift data can impose strong constraints on dark energy models even when the equation of state is oscillatory. Despite the double integral dependence of the distance on the equation of state, precision measurement of the distance-redshift relation for z=0-2 is more incisive than the linear growth factor, CMB last scattering surface distance,

A Promising Approach for Determining Neutrino Mass Hierarchy by Using Supernova Neutrino Detections

open access: yesThe Astrophysical Journal
The determination of neutrino mass hierarchy is crucial for particle physics, astrophysics, and cosmology. In this work, we propose an easy-to-use method to determine the neutrino hierarchy based on core-collapse supernova (CCSN) neutrino detections.

Dark Energy and Dark Matter

open access: yes, 2018
The rudiments of a theory of dark energy. The theoretical result is confronted with the numerical value calculated from the available data. Excellent matching of numerical values resulting in three independent paths makes the approach plausible. The work at hand is analogous to Kepler's laws of planetary orbits. Only Isaac Newton put Kepler's laws on a
