Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals
Advanced Functional Materials, EarlyView.In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

Variable gamma-ray emission from the Be/X-ray transient A0535+26? [PDF]
, 2001 We present a study of the unidentified gamma-ray source 3EG J0542+2610. This source is spatially superposed to the supernova remnant G180.0-1.7, but its time variability makes unlikely a physical link.

Advanced Materials, EarlyView.A spin reorientation transition is generated at hybrid interfaces of Pt‐Co‐organic molecules in the vicinity of room temperature. This spin reorientation transition happens at an ultrafast scale and is controlled either through electrical current or fs laser pulse, introducing perpendicular magnetic anisotropy in formerly planar magnetised samples ...

Galactic cosmic ray spectral measurements with the DAMPE space mission [PDF]
EPJ Web of ConferencesThe space-based DAMPE (DArk Matter Particle Explorer) detector has been taking data since its successful launch in December 2015. Its main scientific goals include the indirect search for dark matter signatures in the cosmic electron and gamma-ray ...

Advanced Optical Materials, EarlyView.Two dimensional (2D) atomically thin materials hold significant promise for next‐generation photodetectors but are limited by low light absorption and scalability challenges. This study presents a high‐performance photodetector integrating liquid metal‐derived 2D SnO2 with CdTe, enabling efficient visible to near‐infrared detection and offering a ...

Theoretical Modeling of the Exceptional GRB 221009A Afterglow
The Astrophysical Journal LettersThe extraordinary gamma-ray burst GRB 221009A provides a great opportunity to investigate the enigmatic origin and evolution of gamma-ray bursts (GRBs). However, the complexity of the observations associated with this GRB provides significant challenges ...

A Gamma-Ray Burst Bibliography, 1973-2001 [PDF]
, 2002 On the average, 1.5 new publications on cosmic gamma-ray bursts enter the literature every day. The total number now exceeds 5300. I describe here a relatively complete bibliography which is on the web, and which can be made available electronically in ...

, 2008 In this paper, I present a summary of the status of γ-ray astronomy in the very high energy band (E > 50GeV), as of early 2007. It covers a selection of results obtained from observations made by ground-based detectors using the atmospheric Cherenkov or air shower techniques, together with short descriptions of some of the present and future ...

State‐of‐the‐Art Solar Blind and X‐Ray Photodetectors Based on Gallium Oxide
Advanced Photonics Research, EarlyView.State‐of‐the‐art Ga2O3‐based solar‐blind UV and X‐ray photodetectors (PDs) are reviewed. Benchmark plots compare responsivity versus specific detectivity for UV PDs (photoconductors, photovoltaic, Schottky, heterojunction, avalanche, and phototransistor types) and sensitivity versus response time for X‐ray detectors based on Ga2O3 bulk crystals, thin ...
