Gravitational Waves Hands-on Workshop 2025

Welcome to the webpage for the Gravitational Waves Hands-on Workshop 2025, an intensive program revolving around a hands-on project, to learn more about gravitational waves and foster collaborations 💪! You will find here links, documents and contacts for the smooth execution of the workshop.

Bullet-point summary

  • Theme: Gravitational waves, and beyond!
  • Goals:
    • Teach students gravitational wave concepts and give them the tooling to study them
    • Foster collaboration and network awareness in East-Asia
  • To whom: 12 enthusiastic early career scientists.
  • When: from the 27th of November to the 1st of December.
  • Where: at The Chinese University of Hong Kong

Requirements

⚠️ Be sure to bring in your own laptop ⚠️

  • Basic knowledge of general relativity
  • Basic knowledge of cosmology
  • Basic knowledge of gravitational waves and their detection process
  • Good knowledge of Python programming

Hands-on project description

  • Title: Correlating distributions of gravitational wave (GW) sources with γ-ray bursts (GRBs) and galaxies
  • Goals:
    • Learn how to get the localization data of GW sources, galaxies and GRBs
    • Learn how to test for correlations between GWs, GRBs and galaxies, across various parameters
      (e.g., the sky localization, the GWs event masses, the galaxy size, etc…)
    • Develop tests for anisotropy in the catalogue of GWs, GRBs and/or galaxies.
  • Details: More details can be found in this descriptive document.
