# Lectures and courses of the IMPRS for gravitational-wave astronomy

## Gravitational Waves

This online course is part of the course catalogue of the Humboldt University of Berlin in Winter 2020. Enrollment at the Humboldt University is not necessary for participation, but registration via Moodle is required.

**Synopsis**: In early 2016, one hundred years after Einstein predicted the existence of gravitational waves on the basis of his theory of General Relativity, LIGO announced the first observation of gravitational waves passing through the Earth emitted by the collision of two black holes one billion four-hundred million light years away. Since then, tens of binary black holes and two neutron stars have been observed by LIGO and Virgo detectors.

In this course we will review what gravitational waves are, how they are produced, what are the main astrophysical and cosmological sources and how we model them, using analytical and numerical relativity. We will also review the quest for gravitational waves, which culminated with the recent discovery by LIGO, and discuss how those new astronomical messengers are detected and how they can unveil the properties of the most extreme astrophysical objects in the universe.

## Making sense of data: introduction to statistics for gravitational-wave astronomy

This first IMPRS course at AEI Potsdam took place in Fall/Winter 2019/2020 and was broadcast to all IMPRS partner institutions.

**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 gives an overview of some key statistical ideas and techniques that are essential for interpreting current and future gravitational wave observations.
