Testing spatial curvature in an anisotropic extension of $w$CDM model with low redshift data Open
In this letter, we report the observational constraints on a Bianchi type I anisotropic extension of $w$CDM model with spatial curvature from observational data including Baryon Acoustic Oscillations (BAO), Cosmic chronometers (CC), Big Ba…

Observational Constraints on generalized dark matter properties in the presence of neutrinos with the final Planck release Open
In this paper, we investigate an extension of the standard $Λ$CDM model by allowing: a temporal evolution in the equation of state (EoS) of DM via Chevallier-Polarski-Linder parametrization, and the constant non-null sound speed. We also c…

Feasibility and impact of a one-stop thyroid clinic in a low- and middle-income country Open
BACKGROUND: The study was done to evaluate the feasibility, safety and outcomes of a one-stop thyroid clinic (OSTC) in a low- and middle-income country (LMIC) setting METHODS: This was a prospective non-randomised case control study consis…

Cosmological parameter analyses using transversal BAO data Open
We investigate observational constraints on cosmological parameters combining 15 measurements of the transversal BAO scale (obtained free of any fiducial cosmology) with Planck–CMB data to explore the parametric space of some cosmological …

Testing the warmness of dark matter Open
Dark matter (DM) as a pressureless perfect fluid provides a good fit of the standard Λ cold dark matter (ΛCDM) model to the astrophysical and cosmological data. In this paper, we investigate two extended properties of DM: a possible time d…

Cosmological bounds on dark matter-photon coupling Open
We investigate an extension of the $\Lambda$CDM model where the dark matter (DM) is coupled to photons, inducing a nonconservation of the numbers of particles for both species, where the DM particles are allowed to dilute throughout the co…
