Second international workshop on particle physics and the early universe (COSMO-98), 1999 The discussion of cosmological parameters used to be a source of embarrassment to cosmologists. Today, measurements of the cosmological parameters are leading the way into the era of precision cosmology.

Probing cosmological parameters with GRBs [PDF]
AIP Conference Proceedings, 2004 In light of the recent finding of the narrow clustering of the geometrically-corrected gamma-ray energies emitted by Gamma Ray Bursts (GRBs), we investigate the possibility to use these sources as standard candles to probe cosmological parameters such as

Cosmic time for multi-component universe [PDF]
Serbian Astronomical Journal, 2020 We determined Weierstrass canonical form of cosmic time formula in the cases of four-component and some three-component universe, assuming the ΛCDM model. In all other cases, we discussed analytical solutions for the cosmic time formula.

A Short Review on the Latest Neutrinos Mass and Number Constraints from Cosmological Observables
Universe, 2022 We review the neutrino science, focusing on its impact on cosmology along with the latest constraints on its mass and number of species. We also discuss its status as a possible solution to some of the recent cosmological tensions, such as the Hubble ...

Designing an Optimal LSST Deep Drilling Program for Cosmology with Type Ia Supernovae
The Astrophysical Journal Supplement Series, 2023 The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) is forecast to collect a large sample of Type Ia supernovae (SNe Ia) expected to be instrumental in unveiling the nature of dark energy.

The Astrophysical Journal Letters, 2023 The light from an extragalactic source at a distance d will arrive at detectors separated by 100 au at times that differ by as much as 120( d /100 Mpc) ^−1 nanoseconds because of the curvature of the wave front. At gigahertz frequencies, the arrival time

Evidence of the fine-structure constant in H0-tension
Physics Letters B, 2021 Modern precision measurements on Hubble expansion H(z) introduce two integral constraints on background models derived from early and late-time cosmology, based on Planck observations of the BAO and, respectively, H0, here normalized to ΛCDM.

Cosmological Tensions and the Transitional Planck Mass Model
The Astrophysical Journal, 2023 In this follow-up analysis, we update previous constraints on the transitional Planck mass (TPM) modified gravity model using the latest version of EFTCAMB and provide new constraints using South Pole Telescope (SPT) and Planck anisotropy data along with

Giant Arc Statistics and Cosmological Parameters [PDF]
, 1999 We study with semi-analytical methods the statistics of pronounced arcs caused by lensing of galaxies by foreground galaxy clusters. For the number density and redshift distribution of rich clusters we use Press-Schechter theory, normalized on the basis ...

A Bias-free Cosmological Analysis with Quasars Alleviating H 0 Tension
The Astrophysical Journal Supplement Series, 2023 Cosmological models and their parameters are widely debated because of theoretical and observational mismatches of the standard cosmological model, especially the current discrepancy between the value of the Hubble constant, H _0 , obtained by Type Ia ...
