Context. The Crab nebula was observed with the HESS stereoscopic Cherenkov-telescope
array between October 2003 and January 2005 for a total of 22.9 h (after data quality …

ABSTRACT The Solar Tower Atmospheric Cerenkov Effect Experiment (STACEE) is a new
ground-based atmospheric Cerenkov telescope for gamma-ray astronomy. STACEE uses …

This paper provides a brief, personal account of the development of ground-based gamma-
ray astronomy, primarily over the last 35 years, with some digressions into the earlier history …

We have measured the gamma-ray fluxes of the blazars Mrk 421 and Mrk 501 in the energy
range between 50 and 350 GeV (1.2 to $8.3\times 10^{25} $ Hz). The detector, called …

Pulsars are highly magnetised rotating neutron stars that emit regular, periodic pulses of
radiation across a wide range of the electromagnetic spectrum. Originally only observed in …

ABSTRACT The Cherenkov Telescope Array (CTA) will be the next generation instrument
for the very high energy gamma-ray astrophysics domain. With its enhanced sensitivity in …

For several years the only experiments sensitive to astrophysical gamma rays with energies
beyond the reach of EGRET but below that of the Cherenkov imaging telescopes have been …
