Viaggiu holographic dark energy in light of DESI DR2
Amlan K. Halder, Andronikos Paliathanasis, Stefano Viaggiu +2
We test the cosmological viability of the Viaggiu holographic dark energy (VHDE) model by using late-time observational data. In particular, we place constraints on the free parame…
The peculiar case of the Viaggiu holographic dark energy
Somnath Saha, Subhajit Saha, Nilanjana Mahata
We study the plausibility of a holographic dark energy (HDE) model using the form of horizon entropy proposed by Viaggiu in 2014. This form of entropy is a generalization of the us…
For a flat Universe, : another coincidence in Cosmology?
Somnath Saha, Subhajit Saha, Nilanjana Mahata
This paper deals with gravitational thermodynamics on the dynamical apparent horizon of an FLRW universe with dissipation. The dissipation is assumed to arise due to adiabatic grav…
Evolution of primordial black holes in an adiabatic FLRW universe with gravitational particle creation
Subhajit Saha, Abdulla Al Mamon, Somnath Saha
We study the evolution of primordial black holes (PBHs) in an adiabatic FLRW universe with dissipation due to bulk viscosity which is considered to be in the form of gravitational…
Constraints on a generalized deceleration parameter from cosmic chronometers
Abdulla Al Mamon
In this paper, we have proposed a generalized parametrization for the deceleration parameter in order to study the evolutionary history of the universe. We have shown that the…
