Limited-Time Offer: Up to 75% Off Coursera Plus!
7000+ certificate courses from Google, Microsoft, IBM, and many more.
The course focuses on understanding waveform systematics in the gravitational-wave inference of tidal parameters and the equation of state from binary neutron star signals. The learning outcomes include gaining insights into the impact of waveform approximants on parameter estimation, especially in loud, high signal-to-noise ratio events observed by advanced detectors. The course covers various waveform models such as PN, EOB, and Phenom, along with discussions on matter effects, adiabatic tides, dynamical tides, and spin-induced effects. The teaching method includes lectures, discussions, and analysis of real data like GW170817. The course is intended for individuals interested in gravitational wave astronomy, parameter estimation, and waveform modeling.
