TL;DR: This is the first direct detection of gravitational waves and the first observation of a binary black hole merger, and these observations demonstrate the existence of binary stellar-mass black hole systems.

TL;DR: In this paper, the authors review the performance of the LIGO instruments during this epoch, the work done to characterize the detectors and their data, and the effect that transient and continuous noise artefacts have on the sensitivity of the detectors to a variety of astrophysical sources.

TL;DR: In this article, the authors inject squeezed states to improve the performance of one of the detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) beyond the quantum noise limit, most notably in the frequency region down to 150 Hz.

TL;DR: This Letter reports the results from a haloscope search for dark matter axions with masses between 2.66 and 2.81 μeV, achieving unprecedented sensitivity by operating a large-volume haloscope at subkelvin temperatures, thereby reducing thermal noise as well as the excess noise from the ultralow-noise superconducting quantum interference device amplifier used for the signal power readout.

TL;DR: The first observation run of the Advanced LIGO detectors started in September 2015 and ended in January 2016 as discussed by the authors, which achieved a strain sensitivity of better than 10^(−23)/√Hz around 100 Hz.
