The Astrophysical Journal, 2023 In this paper, using the latest Pantheon+ sample of Type Ia supernovae, baryon acoustic oscillation measurements, and observational Hubble data, we carry out a joint constraint on the Hubble constant H _0 , the spatial curvature Ω _K , and the sound ...

Novel Theorems on Spacetime Admitting Pseudo‐W2 Curvature Tensor
Journal of Mathematics, Volume 2026, Issue 1, 2026.This paper investigates spacetime manifolds admitting a pseudo‐W2 curvature tensor. We show that a pseudo‐W2 flat spacetime is an Einstein manifold and therefore has constant curvature. Moreover, when the manifold satisfies the Einstein field equations (EFE), with a cosmological constant, the associated energy–momentum tensor is covariantly constant ...

The Hubble Tension Resolved by the DESI Baryon Acoustic Oscillations Measurements
The Astrophysical Journal LettersThe Lambda cold dark matter (ΛCDM) cosmological model provides a good description of a wide range of astrophysical and cosmological observations. However, severe challenges to the phenomenological ΛCDM model have emerged recently, including the Hubble ...

Laser &Photonics Reviews, Volume 19, Issue 24, December 17, 2025.This study presents an improved technique for Localization Optoacoustic Tomography using experimentally‐derived effective point spread functions. The method significantly enhances sub‐pixel localization performance, with applicable potential to relatively under‐sampled scenarios and other imaging modalities, paving the way for new frontiers in super ...

Uncorrelated Estimations of H0 Redshift Evolution from DESI Baryon Acoustic Oscillation Observations
The Astrophysical Journal LettersThe Dark Energy Spectroscopic Instrument (DESI) collaboration recently released the first-year data of baryon acoustic oscillations (BAOs). Based on the five different tracers, the cosmological constraint shows a hint of deviation from the standard ΛCDM ...

Expected value, to a point: Moral decision‐making under background uncertainty
Noûs, Volume 59, Issue 4, Page 1093-1125, December 2025.Abstract Expected value maximization gives plausible guidance for moral decision‐making under uncertainty in many situations. But it has unappetizing implications in ‘Pascalian’ situations involving tiny probabilities of extreme outcomes. This paper shows, first, that under realistic levels of ‘background uncertainty’ about sources of value independent

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract The upper layers of Jupiter's atmosphere, offering critical insights into the planet's deeper structure, are accessible through radio occultation experiments. Since July 2023, NASA's Juno extended mission has provided the first high‐resolution radio occultation measurements since the Voyager era, probing the thermal structure and composition ...

, 2017 There is a new article in Science on the expansion rate of the universe, very much along the lines of my recent post. It is a good read that I recommend. It includes some of the human elements that influence the science.
