Gravitational Waves Data Analysis
Tomás Andrade / Macarena Lagos
This series of hands-on lectures provides a comprehensive introduction to gravitational wave data analysis. Students will explore key techniques such as time series manipulation with event data, matched filtering for detecting modeled signals, and parameter estimation to derive properties of astrophysical sources. The course emphasizes practical experience with essential software tools from the LIGO-Virgo-KAGRA collaboration, including gwpy, pycbc, and bilby.
Binary Stellar Evolution and Star Clusters
Giuliano Iorio / Sara Rastello
Gravitational wave signals offer fascinating insights into extreme objects like black holes and neutron stars while also revealing essential astrophysical information. They open a window into the life cycles of stars and the dynamic environments shaping their evolution.
This series of lectures and hands-on activities introduces the complex processes of stellar and binary evolution, along with dynamical interactions in star clusters, which serve as key formation channels for binary black holes (BBHs). After a theoretical overview, we will present the population synthesis code SEVN and the direct N-body code PeTar, two advanced software tools widely used to study BBH formation pathways.
Through hands-on activities, participants will use SEVN to simulate stellar and binary evolution and PeTar to model star cluster dynamics. By analysing the simulation data, students will identify BBHs and merging BBHs, the progenitors of gravitational wave signals. We will discuss how different formation channels and astrophysical parameters—such as metallicity, initial mass distributions, and cluster dynamics—affect BBH properties and influence BBH formation, as well as the astrophysical significance of gravitational waves.
Black Hole Perturbation Theory – Tidal Deformation and Ringdown
Lam Hui
In this series of lectures we will go over the basics of black hole perturbation theory, and explore two applications: tidal deformation and ring-down. Recent developments, including symmetry understanding and higher order perturbations, will be discussed.
