This first IMPRS course at AEI Potsdam took place from November 20, 2019 to February 5, 2020.
Synopsis: Measurements of the properties of gravitational wave sources are imperfect due to the presence of noise in the gravitational wave interferometers used to detect them. Extracting useful scientific information from these observations therefore requires careful statistical analysis of the data in order to understand the significance of the observed events, the level of uncertainty in the parameter estimates and the implications of the observations for the population from which the sources are drawn. This lecture course will give an overview of some key statistical ideas and techniques that are essential for interpreting current and future gravitational wave observations.
The lecture dates are listed below along with the lecture titles.
The lecture recordings can be found under “course materials” on the pages of the individual lectures.
