Revisiting the equation of state of dark energy from DESI BAO with SNe Ia and CMB

European Physical Journal C: Particles and Fields
The Dark Energy Spectroscopic Instrument (DESI) measurements of baryon acoustic oscillations (BAO) have recently shown a mild preference for dynamical dark energy over the standard $$\mathrm \Lambda $$ Λ CDM model. In this paper, we analyze the $$w_0w_a$$

A High-Finesse Suspended Interferometric Sensor for Macroscopic Quantum Mechanics with Femtometre Sensitivity

Sensors
We present an interferometric sensor for investigating macroscopic quantum mechanics on a table-top scale. The sensor consists of a pair of suspended optical cavities with finesse over 350,000 comprising 10 g fused silica mirrors.

New Constraints on the Lunar Crust and Upper Mantle From Multiple Geophysical Data Sets

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Determining the crust–mantle boundary of the Moon has been an important topic in lunar interior studies. However, strong seismic scattering in the lunar subsurface has made it challenging to identify clear crustal reflections or converted seismic phases.

Theoretical Investigations to Aid in the Prediction of Combined Sewer Overflows in Coastal Urban Watersheds: Case Study of San Francisco

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract Combined sewer systems (CSS) function in about 700 U.S. municipalities, with over 100 near vulnerable coastal waters. Predicting changes due to rainfall, sea level rise (SLR), and groundwater rise is vital for adaptation. This study compares a hydrologic‐hydraulic model (PCSWMM) and a hybrid mass balance method for estimating combined sewer ...

A Predictable Component of the Internal Tide on a Narrow Continental Shelf

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Coastal internal tides are considered unpredictable: harmonic fits to depth‐varying baroclinic velocity explain little variance. We show the depth‐averaged coastal internal tide is predictable from astronomical forcing. On the inner shelf, coastal trapped wave (CTW) modes are approximately depth‐uniform, so depth‐averaging recovers their ...

From Nonparametric Distance Reconstruction to Testing the Etherington Relation and Cosmic Curvature Using 2D and 3D BAO Measurements

The Astrophysical Journal
We present a joint test of cosmic curvature, Ω _k _0 , and the cosmic distance–duality relation (CDDR) using the Etherington relation, which connects the luminosity and angular diameter distances at the same redshift. In this work, we combine the angular

Altitude Dependence of Quasi‐Static Potential Drop: The Effect of Ionospheric Protons

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Using an improved kinetic model that incorporates cold ionospheric protons and oxygen ions, we investigate the factors controlling the altitude range of the auroral acceleration region (AAR). In this model, parallel electric fields are generated via Dispersive Alfven Wave‐ Modified electron Acoustic Wave (DAW‐MEAW) coupling and sustained by ...

Influence of Dynamical Friction on the Unstable Manifolds of Lagrange Points in Barred Galaxies

Astronomische Nachrichten, Volume 347, Issue 8, October 2026.
ABSTRACT Some time ago the idea has been proposed that rings and spirals in barred galaxies are shaped by the unstable manifolds of the Lagrange points sitting near the ends of the bar. The topic of the present article is an investigation of whether the numerical support for this suggestion can be improved by the inclusion of dynamical friction into ...
