Hanford Site comprehensive site compliance evaluation report [PDF]

open access: yes, 1995
This document is the second annual submittal by WHC, ICF/KH, PNL and BHI and contains the results of inspections of the storm water outfalls listed in the Hanford Site Storm Water Pollution Prevention Plan (SWPPP) (WHC 1993a) as required by General Permit No. WA-R-00- 000F (WA-R-00-A17F): This report also describes the methods used to conduct the Storm

Optimal combination of signals from co-located gravitational wave interferometers for use in searches for a stochastic background [PDF]

open access: yes, 2004
This article derives an optimal (i.e., unbiased, minimum variance) estimator for the pseudo-detector strain for a pair of co-located gravitational wave interferometers (such as the pair of LIGO interferometers at its Hanford Observatory), allowing for ...

Quantitative Modeling of Microbial Population Responses to Chronic Irradiation Combined with Other Stressors. [PDF]

open access: yesPLoS ONE, 2016
Microbial population responses to combined effects of chronic irradiation and other stressors (chemical contaminants, other sub-optimal conditions) are important for ecosystem functioning and bioremediation in radionuclide-contaminated areas ...

Improving the Sensitivity of Advanced LIGO Using Noise Subtraction [PDF]

open access: yes, 2019
This paper presents an adaptable, parallelizable method for subtracting linearly coupled noise from Advanced LIGO data. We explain the features developed to ensure that the process is robust enough to handle the variability present in Advanced LIGO data.

Long term study of the seismic environment at LIGO

open access: yes, 2004
The LIGO experiment aims to detect and study gravitational waves using ground based laser interferometry. A critical factor to the performance of the interferometers, and a major consideration in the design of possible future upgrades, is isolation of ...

Methods for Reducing False Alarms in Searches for Compact Binary Coalescences in LIGO Data [PDF]

open access: yes, 2010
The LIGO detectors are sensitive to a variety of noise transients of non-astrophysical origin. Instrumental glitches and environmental disturbances increase the false alarm rate in the searches for gravitational waves. Using times already identified when

Gravitational wave burst vetoes in the LIGO S2 and S3 data analyses

open access: yes, 2005
The LIGO detectors collected about 4 months of data in 2003-2004 during two science runs, S2 and S3. Several environmental and auxiliary channels that monitor the instruments' physical environment and overall interferometric operation were analyzed in ...

Search for gravitational wave bursts in LIGO's third science run [PDF]

open access: yes, 2005
We report on a search for gravitational wave bursts in data from the three LIGO interferometric detectors during their third science run. The search targets subsecond bursts in the frequency range 100-1100 Hz for which no waveform model is assumed, and ...
