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: In this paper, a quasi-periodic quasar with roughly 12-year optical cycles displays prominent outbursts that are predictable in a binary black hole model, and the model predicted a major optical outburst in 2015 December.

TL;DR: In this paper, the transit times of the exoplanet WASP-12 b do not follow a linear ephemeris with a 5σ confidence level, and they may be approximated with a quadratic ephemerISR that gives a change rate in the orbital period of (−2.56 ± 0.40) × 10-2 s yr-1.

TL;DR: In this article, the authors found that the outburst did occur within the expected time range, peaking on 2015 December 5 at magnitude 12.9 in the optical R-band, based on Swift/XRT satellite measurements and optical polarization data.
