Exotic compact object search results using an expanded template bank

ORAL

Abstract

Systems that contain exotic compact objects can go undetected by current template-based gravitational wave searches, especially for objects with large spin-induced quadrupole moments. This is particularly true for low mass binaries, where phase evolution due to these quadrupole moments can be large. To remedy this, we have have carried out a matched-filter search of public gravitational wave data using GstLAL, and using templates which account for large dimensionless quadrupole parameters. To make the search feasible, we constructed reduced-dimensional models with high effectualness for our templates, and implemented a novel approach to creating random template banks. I will discuss our methods and preliminary results.
