The MACE (Major Atmospheric Cherenkov Experiment) telescope at Hanle utilises the Cherenkov effect to detect high-energy gamma rays from astrophysical sources.

The Trump administration’s assault on elite East Coast schools, which the president says must be punished for indoctrinating students with leftist ideology and allowing antisemitism to flourish ...

The idea of a particle that races faster than light has long fascinated physicists. Known as the tachyon, it was originally dreamed up to help untangle paradoxes in quantum theory and relativity.

Cosmic gamma rays are a special probe to investigate sudden cosmic events in the universe. Unlike thermal emission, which ranges from radio to X-rays, cosmic gamma rays are often a direct probe of ...

Microwave photonics articles from across Nature Portfolio Microwave photonics is the practical application of electromagnetic waves with a wavelength between one millimetre and one meter ...

This paper describes a new design of a relativistic Cherenkov oscillator with strong modulation of the e-beam current at the input of two-sectioned slow-wave structure, as well as numerical and ...

In this paper, microwave oscillation in which an electromagnetic wave and a continuous cylindrical relativistic electron beam (REB) with no magnetic field are in Cherenkov synchronism was studied.

Advances in Very High Energy Astrophysics summarises the progress made by the third generation of imaging atmospheric Cherenkov telescopes.
