Aharonov–Bohm Effect for Cooper Pairs in Kerr Spacetime: Gravitomagnetic Phase Shifts From Frame Dragging

open access: yesAnnalen der Physik, Volume 538, Issue 8, August 2026.
ABSTRACT The unification of quantum mechanics and general relativity remains a central problem in fundamental physics. Here, we study the gravitomagnetic Aharonov–Bohm (AB) effect for Cooper pairs in Kerr spacetime. Frame‐dragging by a rotating black hole (BH) generates an effective vector potential through the off‐diagonal metric term gtϕ$g_{t\phi }$,

An Instrument for Isomer‐Specific Action Spectroscopy of Charged Clusters: Electronic Spectra of C 14 + and Ca@C 60 +

open access: yesChemistry–Methods, Volume 6, Issue 8, August 2026.
Disentangling spectral congestion of a mixture of isomers in gas‐phase spectroscopy is critical. We present an instrument combining ion mobility, mass spectrometry, and spectroscopy in a cryogenic 3D Paul trap to investigate the isomer‐specific charged clusters and illustrate its performance with the electronic spectra of C14+ and Ca@C60+. Interpreting

AI Based Velocity Calibration for Cassini's Cosmic Dust Analyzer (CDA)

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This paper presents a novel AI‐based velocity calibration method for the Cosmic Dust Analyzer (CDA) onboard the Cassini spacecraft, in particular for impacts on the large Impact Ionization Detector (IID). The legacy polynomial calibration function, derived from laboratory measurements at a dust accelerator facility, assigns a velocity ...

Latitude Survey of Neutrons and Muons to Determine Cosmic Ray Neutron Sensing Yield Functions

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic Ray Neutron Sensing (CRNS) is a ground‐based technique that utilizes epithermal neutron measurements as a proxy for environmental hydrogen content. Similarly to other ground‐based cosmic ray detectors (e.g., neutron monitors), CRNS detectors are affected by the solar cycle and space weather events.

Quasiperiodic Oscillations in GRB 210514A: a Case of a Newborn Supramassive Precessing Magnetar Collapsing into a Black Hole?

open access: yesThe Astrophysical Journal
Magnetar is proposed as one of the possible central engines for a gamma-ray burst (GRB). Recent studies show that if a magnetar has a rotational axis misaligned from the magnetic one, a periodic lightcurve pattern is expected with a period of seconds to ...

Near‐Earth Cosmic Ray Modulation Index ϕ and Neutron Monitor Cutoff Rigidities at Hourly Cadence: Toward an Improved Monitoring of Solar‐Terrestrial Radiation Environment, Space Weather, and Space Climate

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic rays (CRs) are energetic particles originating from galactic and extragalactic sources. When arriving into the solar system and the Sun's heliosphere, they are diverted and modulated by the magnetic activity of the Sun. This modulation can be quantified by the modulation parameter ϕ $\phi $ determined with the Force‐field approximation (

Jovian Auroral Proton Precipitation

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The total power of the Jovian aurora is about 1013–1014 W with ultraviolet emission observed in the Lyman and Werner bands of molecular hydrogen. X‐ray, radio, and infrared emissions have also been observed. The Jovian Auroral Distributions Experiment and the Jovian Energetic Particle Detector Instrument onboard the Juno spacecraft, orbiting ...
