An Efficient Search for Gravitational Waves from Primordial Black Holes

There is increasing interest in sub-solar mass black holes regarding the possibility that they are a component of dark~ matter, due to the limited knowledge regarding its composition. ~We are able to test the primordial black hole theory of dark matter by running a targeted sub-solar mass search using LIGO data. The range and difficulty of the search depends on certain parameters (defined below). We aim to define parameters that produce a search which simultaneously maximizes relative sensitivity and minimizes computational cost. We tested template bank size dependence on several parameter sets, including minimum/maximum frequency, minimum mass, and spin. ~As the template bank size increased, the overall computational cost of the project also increased.~ We determined that larger magnitudes of spin, wider frequency ranges, and smaller masses produce a larger template bank, and subsequently a higher computational cost. ~To obtain the lowest computational cost for this project, we would need to constrain the search parameters as much as possible.~ In the future, we will construct a search such that our parameters are as extensive as possible without substantial computational cost.
