The Lambert equation of state in light of DESI BAO
Vipin Chandra Dubey, Subhajit Saha, Abdulla Al Mamon
The paper proposes a unified dark‑fluid model whose equation of state is expressed using the Lambert W function, and constrains its parameters with DESI BAO, supernova, and Hubble…
Unifying the Dark Sector with the New Generalized Chaplygin Gas: Observational Constraints
Abdulla Al Mamon, Andronikos Paliathanasis, Subhajit Saha
In light of recent cosmological observations, we examine a generalized Chaplygin gas model with a redshift-dependent exponent as a framework for describing the dark energy and dark…
Interacting tachyon with varying mass dark matter
Goutam Mandal, Sudip Mishra, Abdulla Al Mamon +1
This paper presents an investigation of cosmological dynamics of tachyon fluid coupled to varyingmass dark matter particles in the background of spatially flat FLRW universe. The m…
