Abstract
Pulsars are one type of neutron star that emits a beam of electromagnetic radiation with a rate proportional to their rotational speed. This rotational speed can be measured with a precision of up to 10^{-15} seconds. This precision and stability makes pulsars prime candidates for the search for nanohertz gravitational waves. The goal of this research project is to examine radio data of the recycled pulsar PSR J1713+0747 observed with the Green Bank Telescope (GBT). This pulsar is one of the leading objects used for the search for nanohertz gravitational waves. We examine single pulse data which contains individual rotations of the pulsar. We compile the average emission of this pulsar (known as profile emission) to extract the emission windows of single pulses. We extract the arrival times of single pulses to search for indicators of timing deviations. That way, we are investigating whether recent emission mode changes in the case of this pulsar can be predicted in advance to account for during gravitational wave searches.
