Hypothetical Waveforms and Unmodeled or Pipeline Searches in Gravitational Wave Astronomy — •Lydia Patton — Virginia Tech, Blacksburg, Virginia, USA

The multiple theoretical and instrumental advances in gravitational wave astronomy (GWA) have allowed for the construction of an increasingly flexible platform for discovery. This paper will investigate novel research methods being constructed on the ground in GWA. It will begin by evaluating the comparison of and contrast between two methods of analysis: the construction of waveforms that incorporate hypothetical parameters for new searches (EOB and novel extended EOB methods), and the use of unmodeled and pipeline-based searches of existing data. In both cases, varying hypothetical assumptions or models allows for more flexible, broad search methods. The question then is how to move from the broader a priori models to the detection of an event. We will examine several recent papers to reconstruct how these broader methods can be used to support novel detection, and examining how search and detection methods work together in this context.
