Continuous Gravitational Waves from Young Neutron Stars

Mr Benjamin Grace

The detection of gravitational waves from colliding black holes and neutron stars has led to many profound discoveries in astronomy. Despite these discoveries, many of the sources of gravitational waves we expect to observe have yet to be detected. One such source is rapidly rotating neutron stars.
Spinning neutron stars are expected to give off nearly monochromatic continuous gravitational waves. Search techniques for continuous gravitational waves rely on this assumption. Young neutron stars however are expected to be spinning more rapidly and slowing down over shorter time periods than long lived neutron stars. Young neutron stars may spin down on time scales of anywhere between seconds and days.
In this talk, I provide a novel adaptation to continuous wave search techniques which allow for them to be sensitive to rapidly changing gravitational wave signals which may originate from young neutron stars. I will begin by first giving an overview of continuous wave search techniques and how they are not suitable for these signals. I will also present the new search technique I have developed and how it is expected to perform during a gravitational wave search.
