![]() ![]() Such lists are used to improve the efficiencies and ResultsĪre provided in the form of lists of line artifacts that can safely be treatedĪs non-astrophysical. We describe a variety of methods used for finding, identifyingĪnd mitigating these artifacts, illustrated with particular examples. Narrow spectral artifacts (lines) due to instrumental or environmentalĭisturbances. These searches can be degraded by the presence of ![]() relic gravitational waves from theīig Bang or superposition of distant astrophysical events such as mergers ofīlack holes or neutron stars.
