TL;DR: In this article, the detection of TeV energy photons from the giant elliptical galaxy Markarian 421 using the Whipple Observatory gamma-ray telescope was reported and the signal has a statistical significance of 6 sigma above background and the flux above 0.5 TeV is 0.3 of that from the Crab Nebula.

TL;DR: In this paper, the authors reported two dramatic outbursts of TeV photons from the active galaxy Markarian 421 (Mrk421) in which the flux increased above the relatively quiescent value by more than a factor of 50, briefly making Mrk421 the brightest TeV source in the sky.

TL;DR: The detection of gamma rays of energy greater than 300 GeV from the BL Lacertae object Mrk 501 demonstrates that extragalactic TeV emission is not unique to Mrk 421.

TL;DR: In this paper, a next generation atmospheric Cherenkov observatory is described which uses the Whipple Observatory gamma-ray telescope as a prototype, with an array of seven imaging telescopes deployed such that they will permit the maximum versatility and will give the highest sensitivity in the 50 GeV-50 TeV band (with maximum sensitivity from 100 GeV to 10 TeV).
