Automated Identification Of Lines In Data From Gravitational Wave Detectors, Thomas A. Cruz
Automated Identification Of Lines In Data From Gravitational Wave Detectors, Thomas A. Cruz
Theses and Dissertations
On the frontier of gravitational wave (GW) astronomy, the LIGO detectors record vast quantities of data that need to be analyzed constantly for rare and transient GW signals. A foundational problem in LIGO data analysis is the identification of spectral line features in the Power Spectral Density (PSD) of the data. Such line features correspond to high power terrestrial or instrumental signals that must be removed from the data before any search for GW signals can take place. In this study the method developed aims to automate the extraction of the frequencies and bandwidths of the lines, treated as sharp …
