Creator:: Connolly, Genevieve J.
Abstract:: Gravitational waves (GWs) are disturbances in spacetime that can be caused by events such as black hole mergers and supernovae, as well as continuous sources such as binary star systems. GWs offer a new avenue of astrophysical research and can reveal information about the early universe. GW detection can be...

Creator:: Nye, Brandon J.
Abstract:: Detecting gravitational waves is a topic at the forefront of physics. The first gravitational wave was detected by LIGO in 2015. This wave had a frequency in the 10s of Hz. This project is focused on detecting gravitational waves on the nanohertz spectrum using a pulsar timing array. This array...

Creator:: Ashby, Andrew
Abstract:: The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is an international collaboration that seeks to use perturbations in the time of arrivals of pulsar signals to detect gravitational waves in the nanohertz range of frequencies. The 15-year data set will be released as of June 2023. It is a...

Creator:: Laal, Nima
Abstract:: I led a collaborative project involving a search for an evidence of a gravitational wave background (GWB) with all the spatial correlations allowed by general metric theories of gravity using NANOGrav’s 12.5 year data set. The search found no substantial evidence in favor of the existence of such correlations. The...

Creator:: Laal, Nima
Abstract:: Given the recent advancements in the field of pulsar timing pertaining to the detection of a stochastic gravitational wave background (GWB), it is now the perfect time to perform tests of gravity via exploration of the correlation signature between the timing data of pairs of pulsars induced by the polarization...

Creator:: Downing, Jaden
Abstract:: The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) times periodic signals from pulsars as a method of detecting gravitational waves. NANOGrav detects waves emitted in the nanohertz frequency range, a range lower than those previously explored by other organizations. This allows for the study of rarely observed sources such...

Creator:: Díaz, Ian H.
Abstract:: By studying gravitational waves, we can gain new insights into the merging events between massive objects such as black holes as well as neutron stars. Moreover, studying low-frequency waves allows us to observe merging events between supermassive black holes at the centers of galaxies, which in turn allows us to...
