Context. The direct empirical determination of the local value of the Hubble constant (H0) has markedly advanced thanks to improved instrumentation, measurement techniques, and distance estimators.

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures
Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.

The Cosmological Parameters (2021)
This is a review article for The Review of Particle Physics 2022 (aka the Particle Data Book). It forms a compact review of knowledge of the cosmological parameters near the end of 2021. Topics included are Parametrizing the Universe; Extensions to the standard model; Probes; Bringing observations together; Outlook for the future.

In this paper, we test the cosmic distance duality relation (CDDR), as required by the Etherington reciprocity theorem, which connects the angular diameter distance and the luminosity distance via the relation D _L ( z ) = D _A ( z )(1 + z ) ^2 .

A Universal Equation to Predict Ωm from Halo and Galaxy Catalogs
We discover analytic equations that can infer the value of Ω _m from the positions and velocity moduli of halo and galaxy catalogs. The equations are derived by combining a tailored graph neural network (GNN) architecture with symbolic regression.

Cosmological and Solar System Consequences of f(R,T) Gravity Models
To find more deliberate f(R,T) cosmological solutions, we proceed our previous paper further by studying some new aspects of the considered models via investigation of some new cosmological parameters/quantities to attain the most acceptable cosmological

In June 2023, the Laje River, located in the traditional territory of the Wari’ Indigenous people in Rondônia, Brazil, was declared a legal entity, an earth being, with rights, following the co‐ordinated action of an indigenous councillor and non‐indigenous activists.

Global Cosmological Parameters [PDF]
The determination of the global cosmological parameters is discussed. It is argued that the Hubble constant is likely to lie between 75 and 100km s-1Mpc-1, and a low value (H 0 ≈ 50km s-1Mpc-1) is quite unlikely. It is also shown that the current observational evidence supports a low density (typically Ω ≈ 0.1) universe. Combining these parameters with

The Omh ^2 ( z _i , z _j ) two-point diagnostics was proposed as a litmus test of the ΛCDM model, and measurements of the cosmic expansion rate H ( z ) have been extensively used to perform this test.
