This advancement presents significant challenges for scientists, who must now develop theoretical frameworks and data-analysis tools to fully utilize LISA's capabilities. To address these needs, around 140 researchers will gather at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI) in the Potsdam Science Park from September 2 to 6, 2024, for the "Fundamental Physics Meets Waveforms with LISA" workshop.

LISA is expected to detect gravitational waves in the 0.1 mHz to 0.1 Hz range, a frequency window inaccessible from Earth. This range includes various strong gravitational-wave sources such as binary systems of massive black holes, smaller black holes interacting with larger ones, and close binary stars within our galaxy.

LISA's ability to observe stellar-mass black hole binaries long before their merger, as well as a potential gravitational-wave background and unexpected sources, opens up new opportunities for discovery.

New Challenges, New Tools

To maximize LISA's scientific potential, accurate predictions of gravitational waveforms for these new sources are critical. Moreover, advanced computational methods and machine-learning techniques are necessary for effective and precise LISA data analysis.

The workshop will unite the LISA Consortium's Fundamental Physics and Waveform Working Groups to:

- Discuss the theoretical and data-analysis advancements required for strong-field tests of General Relativity with LISA and to explore black hole physics.

- Identify key waveform developments needed for LISA's data validation and scientific exploration.

The workshop is organized by the Department of Astrophysical and Cosmological Relativity at AEI, which is instrumental in preparing for LISA's scientific mission.
