Abstract:
The Advanced Laser Interferometer Gravitational-wave Observatory (LIGO)
detectors have completed their initial upgrade phase and will enter the first
observing run in late 2015, with detector sensitivity expected to improve in
future runs. Through the combined efforts of on-site commissioners and the
Detector Characterization group of the LIGO Scientific Collaboration,
interferometer performance, in terms of data quality, at both LIGO
observatories has vastly improved from the start of commissioning efforts to
present. Advanced LIGO has already surpassed Enhanced LIGO in sensitivity, and
the rate of noise transients, which would negatively impact astrophysical
searches, has improved. Here we give details of some of the work which has
taken place to better the quality of the LIGO data ahead of the first observing
run.
