Detecting gravitational waves — •Markus Pössel — Haus der Astronomie / Max-Planck-Institut für Astronomie, Heidelberg

In this tutorial, we will explore the basics of gravitational wave detection, from pulsar timing to interferometric detectors (with a sidelong glance at resonant detectors). I will try to keep the mathematics as simple as possible, resorting to models and analogies (e.g. with cosmic expansion) wherever feasible. Gravitational waves only interact very weakly with our detectors, which means a gravitational wave signal has plenty of competition in the form of noise. We will consider the most important types of noise, and examine some of the techniques used by detectors like LIGO and Virgo for noise suppression.
