A Multiwavelength Investigation of PSR J2229+6114 and its Pulsar Wind Nebula in the Radio, X-Ray, and Gamma-Ray Bands

The Astrophysical Journal, 2023
G106.3+2.7, commonly considered to be a composite supernova remnant (SNR), is characterized by a boomerang-shaped pulsar wind nebula (PWN) and two distinct (“head” and “tail”) regions in the radio band. A discovery of very-high-energy gamma-ray emission (

Very High Energy Gamma-Ray Observations of the Galactic Centre Region [PDF]

, 2008
Recent progress in pushing the sensitivity of the Imaging Atmospheric Cherenkov Technique into the 10 mCrab regime has enabled first sensitive observations of the innermost few 100 pc of the Milky Way in Very High Energy (VHE; >100 GeV) gamma rays. These

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

Advanced Functional Materials, EarlyView.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

Monte Carlo studies on the sensitivity of the HEGRA imaging atmospheric Cerenkov telescope system in observations of extended gamma-ray sources

, 2002
In this paper, we present the results of Monte Carlo simulations of atmospheric showers induced by diffuse gamma rays as detected by the high-energy gamma ray astronomy (HEGRA) system of five imaging atmospheric Cerenkov telescopes (IACTs).

Present and future gamma-ray burst experiments [PDF]

, 1998
Gamma-ray burst counterpart studies require small, prompt error boxes. Today, there are several missions which can provide them: BeppoSAX, the Rossi X-Ray Timing Explorer, and the 3rd Interplanetary Network.

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime

Advanced Functional Materials, EarlyView.
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

Gamma rays from compact binary system

, 2008
Some of the very high energy (VHE) gamma-ray sources detected with the modern generation of Cherenkov telescopes have been identified with previously known X-ray binary systems.

Gamma Ray Astronomy with ARGO-YBJ [PDF]

AIP Conference Proceedings, 2008
ARGO‐YBJ is the first EAS detector combining a very high mountain altitude (4300 m a.s.1.) to a “full coverage” detection surface. These features allow ARGO‐YBJ to work with an energy threshold as low as a few hundreds GeV. The high duty cycle and the large field of view (∼2 sr) make ARGO‐YBJ suitable to monitor the gamma ray sky, searching for unknown

Nitrogen‐Vacancy Magnetometry of Edge Magnetism in WS2 Flakes

Advanced Functional Materials, EarlyView.
Using nitrogen‐vacancy magnetometry, the authors visualize room‐temperature stray magnetic fields localized at the edges of WS2 flakes. Their measurements reveal edge‐specific magnetization consistent with spin canting in antiferromagnetically coupled edge states.
