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 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.
Journal ArticleDOI
Quasi-periodic Oscillations of ~15 Minutes in the Optical Light Curve of the BL Lac S5 0716+714
TL;DR: In this paper, the authors obtained optical (R band) observations of the blazar S5 0716+714 at a very fast cadence of 10 s. Using several different techniques, they find fluctuations with an approximately 15 minute quasi-period to be present in the first portion of these data at a >3σ confidence level.

TL;DR: The ISOGAL project is an infrared survey of specific regions sampling the Galactic Plane selected to provide information on Galactic structure, stellar populations, stellar mass-loss and the recent star formation history of the inner disk and Bulge of the Galaxy as discussed by the authors.
Journal ArticleDOI
Infrared dark clouds from the ISOGAL survey ? Constraints on the interstellar extinction curve
TL;DR: In this article, a multiresolution analysis of the images leads to a catalogue of infrared dark clouds, most of which are condensed cores of large molecular clouds, seen in absorption in front of the diuse galactic emission.
