GROUND-BASED GAMMA-RAY ASTRONOMY [PDF]
International Journal of Modern Physics A, 2005 Very High Energy Gamma-Ray Astronomy (the measurement of γ above 10 GeV) is a rather young but fast evolving field. In the past 16 years some 20 sources have been discovered, about half of them are firmly established and seen with high significance by more than one experiment.

Ground-Based Gamma Ray Astronomy [PDF]
Brazilian Journal of Physics, 2014 This paper is the write-up of a rapporteur talk given by the author at the 33rd International Cosmic Ray Conference in Rio de Janeiro, Brazil, in 2013. It attempts to summarize results and developments in ground-based gamma-ray observations and instrumentation from among the $\sim300$ submissions to the gamma-ray sessions of the meeting.

Ground-based gamma-ray astronomy [PDF]
AIP Conference Proceedings, 2000 Ground-based gamma-ray astronomy has become an active astrophysical discipline with four confirmed sources of TeV gamma rays, two plerionic supernova remnants (SNRs) and two BL Lac objects (BL Lacs). An additional nine objects (one plerion, three shell-type SNRs, one X-ray binary, and four BL Lacs) have been detected but have not been confirmed by ...

Precision engineering for astronomy: historical origins and the future revolution in ground-based astronomy [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Abstract Since the dawn of civilization, the human race has pushed technology to the limit to study the heavens in ever-increasing detail. As astronomical instruments have evolved from those built by Tycho Brahe in the sixteenth century, through Galileo and Newton in the seventeenth, to the present day, astronomers have made ever more
