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: 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.

TL;DR: In this paper, the authors present the seismic isolation instrumentation and strategy developed for Advanced LIGO interferometers and present the performance recently achieved with the Advanced LigO observatory.

TL;DR: The seismic isolation strategy and instrumentation developed for the Advanced LIGO observatories as mentioned in this paper summarizes over a decade of research on active inertial isolation and shows the performance recently achieved at the advanced LIGA observatories.

TL;DR: In this paper, the authors describe the design, modeling and testing of a prototype of a stack suitable for use in the Laser Interferometer Gravitational-wave Observatory (LIGO), which is a four-stage elastomer (spring) and stainless steel (mass) stack, consisting of a table resting on three separate legs of three layers each.
