Applying Polynomial Search Searching for gravitational waves from neutron stars in binary systems in O3b strain data and the Sco X-1 pipeline comparison

Neutron stars in binary systems are thought to generate continuous gravitational waves that could possibly be detected by Earth-based observatories, such as Virgo, LIGO and KAGRA, provided a sufficiently accurate model of the signal is available. As the characteristics of the signal depend on several parameters that are unknown for binary systems that have not been observed by electromagnetic means, a great number of signal templates would be needed for an exhaustive all-sky search that models every possible signal. Considering that the available computation time is limited, a method is required that yields a good approximation of expected signals with a greatly reduced number of templates.
This thesis discusses an approach called Polynomial Search and presents results for a sample analysis on Virgo O3b data and a comparison with other analysis methods for simulated signals from a binary system known as Sco X-1.
