Boundary‐Only Weak Deflection by Regular Black Holes, Black‐Bounces, Wormholes, and Static Quadrupolar Spacetimes

Fortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT We apply the boundary‐only isothermal formulation of finite‐distance weak gravitational deflection to regular black holes, black‐bounces, traversable wormholes, non‐asymptotically flat backgrounds, and static quadrupolar spacetimes. The methodological advance is not a new value for a known bending angle.

Polychromatic Population of Bioluminescent Organisms in the Deep Pacific Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract We present a comprehensive study of deep‐sea bioluminescent organisms in the Cascadia Basin, Northeast Pacific Ocean, based on four years (2020–2023) of in situ measurements using STRings for Absorption length in Water instruments. Analysis of over 1.3 million camera images and continuous photomultiplier tube recordings revealed that ...

Proposed experiments to detect keV-range sterile neutrinos using energy-momentum reconstruction of beta decay or K-capture events

New Journal of Physics, 2019
Sterile neutrinos in the keV mass range may constitute the galactic dark matter. Various proposed direct detection and laboratory searches are summarized.

Structural Response of Laser‐Driven Shock Compressed Albite

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Plagioclase records characteristic shock features that constrain meteorite impact conditions, but its phase evolution along the Hugoniot remains unresolved. We investigated shock‐induced phase transition in albite using in situ X‐ray diffraction during laser‐driven shock at 14–66 GPa. Albite retained its crystal structure up to at least 14 GPa

Work Versus Force: Simultaneous Processes for Describing Interactions

Advanced Physics Research, Volume 5, Issue 6, June 2026.
ABSTRACT Achieving a unified description of interactions remains an open challenge in theoretical physics, which currently describes four fundamental forces. This situation may be viewed differently when interactions are formulated in terms of processes (work as actio) rather than forces (force as actio), not only at the macroscopic level but also at ...

The imprints of massive neutrinos on the three-point correlation function of large-scale structures

Astronomy & Astrophysics
Aims. Free-streaming of cosmic neutrinos affects the distribution and growth of cosmic structures on small scales. This enables the sum of neutrino masses Mν to be constrained from clustering studies.

GUT Physics in the Era of the LHC

Frontiers in Physics, 2019
Grand Unified Theories (GUTs) are one of the most interesting high-energy completions of the Standard Model, because they provide a rich, powerful and elegant group-theoretical framework able to resolve a variety of problems remaining in our current ...

Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei

Astronomische Nachrichten, Volume 347, Issue 5, June 2026.
ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

Probing the statistical correlation of optical tidal disruption events with high-energy neutrinos

Astronomy & Astrophysics
High-energy (HE) neutrinos have been observed by the IceCube (IC) Neutrino Observatory for over a decade. Nevertheless, the astrophysical origin and the responsible mechanisms producing these HE neutrinos are still a mystery, with many astrophysical ...
