Daring Chinese telescope is poised to transform astronomy

A focusing telescope for gamma-ray astronomy

With the development of the Laue Lens, gamma-ray astronomy is presently realizing the step that virtually all branches of astronomy have accomplished since Lippershey’s invention 400 years ago: the focusing telescope. In a Laue lens, gamma-rays interact coherently inside a crystal via Bragg-diffraction; a large number of diffraction crystals are oriented in a way to deviate incident photons ont...

Editorial: Daring to Speak Out

When we commented on the Brussels bombings in Issue 3, we did not imagine that further shocking violence would be in the forefront of our minds only a few months later. Two horrific events in recent weeks have brought tragedy to the lives of individuals and families and forced into public consciousness issues of principle which lie at their heart. The mass shootings in the early hours of Sunday...

The Magic Telescope Project for Gamma Astronomy above 10 Gev

A project to construct a 17 m diameter imaging air Čerenkov telescope, called the MAGIC Telescope, is described. The aim of the project is to close the observation gap in the γ-ray sky extending from 10 GeV as the highest energy measurable by space-borne experiments to 300 GeV, the lowest energy measurable by the current generation of ground-based Čerenkov telescopes. The MAGIC Telescope will i...
