Course description:
Black holes are among the most unique objects in the Universe from a theoretical and observational perspective. Their study promises to deepen our understanding about gravity, its connection with other fundamental forces and its role in the formation and evolution of the cosmos. Black holes are nowadays also a central piece of the astronomical program from the imaging of the Event Horizon Telescope to the gravitational waves detected by LIGO, Virgo and KAGRA.

In this course we will explore the fundamentals of black hole theory and their observational evidence. We will then focus on gravitational wave radiation from the coalescence of compact binaries. The goal of the course is to set the stage for students to understand the basis and open questions of black hole theory and gravitational wave observations.

This course is designed for master and graduate students. Previous knowledge of General Relativity, for example attending the General Relativity and Cosmology course in Block 3, is a prerequisite.

Along the course students will follow in person lectures, read additional materials, work on exercise assignments and a final exam.

Data & Project @ NBI

I will be supervising projects for the Data & Project course at the Niels Bohr Institute in the spring of 2024. The project details are:

Title: The furthest black hole mergers
Description: Gravitational waves from the coalescence of binary black holes can be detected up to billion of years ago. Distant galaxies act as magnifying glasses that allow us to detected such mergers even further. This project will use state-of-the-art gravitational wave data analysis techniques to explore the furthest black hole merger that could be detected with current detectors. Observing such mergers in real data would have profound implications for our understanding of the astrophysical formation of black holes. Students will interact also with other members of the NBI LIGO group
