The Hall Effects of Vortex Light in Optical Materials
Advanced Photonics Research, EarlyView.This article models optical materials as curved spacetime to investigate light propagation, finding that the deflection angle for light with spin σ and intrinsic orbital angular momentum ℓ follows ϑ ∝ 2σ + ℓ$\vartheta \propto 2 \text{&sgr; } + ℓ$.Wei‐Si Qiu, Li‐Li Yang, Dan‐Dan Lian, Peng‐Ming Zhang +3 morewiley +1 more sourceInitial results from COMPTEL—an overview [PDF]
, 1993 COMPTEL is presently completing the first full sky survey in MeV gamma‐ray astronomy (0.7 to 30 MeV). An overview of initial results from the survey is given: among these are the observations of the Crab and Vela pulsars with unprecedented accuracy, the ...Bennett, K, Bloemen, H, Collmar, W, Connors, A, de Vries, C, deBoer, H, den Herder, J W, Diehl, R, Forrest, D J, Hermsen, W, Kuiper, L, Lichti, G G, McConnell, Mark L, Morris, D, Ryan, James M., Schonfelder, V, Stacy, G, Steinle, H, Strong, A W, Swanenburg, B, Taylor, B G, VanDijk, R, Varendorff, M, Winkler, C +23 morecore +2 more sourcesHigh‐Sensitivity Perovskite γ‐Ray Detectors Enhanced by Device Engineering Toward Energy Spectroscopy Imaging
Advanced Science, EarlyView.Optimized electrode configuration in perovskite γ‐ray detectors achieves enhanced energy resolution from 7% to 1.9% by reshaping bias electric fields and reducing noise. A novel spectral‐enhanced imaging strategy is developed, utilizing spectral dimensions to improve image contrast and quality.Ken Qin, Jia‐He Zhang, Ruo‐Long Zhou, Xue Sun, He‐Xuan Wang, Jia‐Li Peng, Min‐Shu Zhang, Guan‐Hua Dun, Dan Xie, He Tian, Yi Yang, Tian‐Ling Ren +11 morewiley +1 more sourceVery High-energy Gamma-Ray Episodic Activity of Radio Galaxy NGC 1275 in 2022–2023 Measured with MACE
The Astrophysical Journal LettersThe radio galaxy NGC 1275, located at the central region of Perseus cluster, is a well-known very high-energy (VHE) gamma-ray emitter. The Major Atmospheric Cherenkov Experiment Telescope has detected two distinct episodes of VHE ( E > 80 GeV) gamma-ray ...S. Godambe, N. Mankuzhiyil, C. Borwankar, B. Ghosal, A. Tolamatti, M. Pal, P.

confinement in the era of CTA
, 2012 Galactic cosmic rays are commonly believed to be accelerated at supernova
remnants via diffusive shock acceleration. Despite the popularity of this idea,
a conclusive proof for its validity is still missing.A. Bamba, A. Marcowith, Acharya B. S., Actis M., Aghajani T., CTA Consortium, D. Hadasch, D. F. Torres, E. Bissaldi, E. d. Cea, E. d.

, 2023 The launch of the Fermi satellite in 2008, with its Large Area Telescope (LAT) on board, has opened a new era for the study of gamma-ray sources at GeV ($10^9$ eV) energies. Similarly, the commissioning of the third generation of imaging atmospheric Cherenkov telescopes (IACTs) - H.E.S.S., MAGIC, and VERITAS - in the mid-2000's has firmly established ...Malyshev, Denys, Mohrmann, Larsopenaire +2 more sourcesOne‐Size‐Fits‐All: A Universal Binding Site for Single‐Layer Metal Cluster Self‐Assembly
Advanced Science, EarlyView.A universal strategy enables the formation of single‐layer metal clusters (SLMC) across 21 elements by harnessing vacancy defects as binding sites. Crucially, synthesis occurs without reactive species, preventing site passivation and ensuring strong metal–surface bonding.Emerson C. Kohlrausch, Sadegh Ghaderzadeh, Gazi N.
