Kaniadakis Holographic Dark Energy Behavior in f(Q) Theory

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
ABSTRACT In this study, the cosmological behavior of the Kaniadakis holographic dark energy model is investigated under the f(Q)$f(Q)$ theory within the framework of a flat Friedmann–Robertson–Walker (FRW) universe. The generalized holographic energy density based on Kaniadakis entropy is modeled using the Hubble horizon infrared cutoff scale, and the ...

Observation of Forbush Decreases and GLE‐74 Recorded During Ground‐Level Neutron Monitoring Survey From Various Sites

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Ground‐level neutron monitors (NMs) are essential tools for monitoring space weather events, including the detection and alerting of ground‐level enhancement (GLE) events. This study presents findings from a neutron monitoring survey using two compact N50L neutron slab‐based subsystems deployed across various field sites in the United Kingdom (

The Ammann–Kramer–Neri tiling model of a P‐ZnMgEr Bergman‐type quasicrystal based on in‐house X‐ray diffraction

Acta Crystallographica Section B, Volume 82, Issue 2, Page 175-185, April 2026.
A structural solution is presented of a primitive icosahedral ZnMgEr quasicrystal representing the Bergman‐type family. The structure model is based on atomic decoration of the Ammann–Kramer–Neri tiling.This study presents the atomic structure solution of a primitive icosahedral Zn70.83Mg20.31Er8.86 quasicrystal using in‐house X‐ray diffraction and the

Model calculations for cosmogenic nuclides in meteorites and the lunar surface. 1. Long‐lived radionuclides

Meteoritics &Planetary Science, Volume 61, Issue 4, Page 600-620, April 2026.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Engineering a Stable Solid–Electrolyte Interphase through a Novel Trifluoromethyl‐Free Lithium Salt for Lithium Metal Polymer Batteries

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...

Neutrino annihilation in Type II supernovae

The Astrophysical Journal, 1987
Neutrino-antineutrino annihilation into electrons and positrons can deposit > 1051 ergs above the neutrino- sphere of a Type II supernova. All species of neutrino contribute roughly equally to the deposited energy. This process, which appears not to have been included in numerical calculations of supernova explosions, may help to drive off the stellar ...
