TL;DR: The ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes as mentioned in this paper, which is an international initiative to build the next generation instrument, with a factor of 5-10 improvement in sensitivity in the 100 GeV-10 TeV range and the extension to energies well below 100GeV and above 100 TeV.

TL;DR: The Cherenkov Telescope Array (CTA) as discussed by the authors is a very high-energy (VHE) gamma ray observatory with an international collaboration with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America.

TL;DR: The Antikythera Mechanism as discussed by the authors is a unique Greek geared device, constructed around the end of the second century bc. It is known that it calculated and displayed celestial information, particularly cycles such as the phases of the moon and a luni-solar calendar.

TL;DR: In this paper, the authors report results from a multi-wavelength observing campaign conducted during 2000 March on the flare star AD Leo and find that the emission properties are remarkably similar even for flares of very different evolutionary morphology.

TL;DR: In this paper, the intensity oscillations observed in the gradual phase of a white-light flare on the RS CV n binary II Peg were analyzed using the Fast Fourier Transform power spectra and Wavelet analysis.
