Title: Towards Observational Tests of Neutron-Star Universality
 
Abstract: The growing number of neutron-star observations, including (but not limited to) gravitational waves and pulsar timing, are expected to greatly improve our understanding of the neutron-star equation of state (EOS). While different EOSs predict different mass-radius relations for NSs, Yagi & Yunes (2013) have shown that other NS bulk properties such as the moment of inertia, tidal Love number, and quadrupole moment appear to obey relations that are approximately insensitive to the EOS. I will discuss the approximately universal I-Love-Q relations and their applications in GW observations. I will also discuss pulsar timing observations in radio and X-rays, and how independent NS measurements from GW observations and pulsar-timing observations can be used to test the approximate NS universality that the I-Love-Q relations imply.
