Listening to the Cosmos: New Frontiers in Gravitational Wave Physics

Abstract

The first detection of gravitational waves from the Ligo-Virgo-Kagra collaboration and the recent results of several pulsar timing arrays have opened the exploration of the gravitational wave Universe. Over the next decade, several other ground and space-based experiments will join this exploration and allow us to access a broad band of the gravitational wave spectrum. This new exploration comes with a series of challenges that can only be overcome through close collaboration between experimentalists and theorists. This workshop will bring together experts working on the experiments enabling this exploration, as well as particle physicists and cosmologists, to discuss the open challenges that this new exploration presents and highlight the synergies between these different communities.

Agenda INDICO

Topics

Week 1 (24th - 30th August): Pulsar Timing Arrays
Recent evidence for a nanohertz gravitational-wave background has opened a new window on the universe, but its origin remains uncertain. This workshop brings together experts from pulsar timing and the broader GW community to: (1) discuss current results and their interpretation, (2) improve analysis methods for future datasets, and (3) explore implications for astrophysics, cosmology, and particle physics.

Week 2 (31st August - 6th September): Space-Based GW Detectors
LISA will open the milli-Hertz gravitational-wave band, revealing thousands of overlapping astrophysical signals and creating major challenges for data analysis and waveform modeling. This workshop brings together waveform modelers, astrophysicists, and data analysts to: (1) identify key scientific challenges, (2) develop new approaches, and (3) foster cross-disciplinary collaborations.

Week 3 (7th - 13th September): Conference Week

Week 4 (14th - 20th September): Ground-Based GW Detectors
The LVK network has observed hundreds of compact-binary coalescences, establishing gravitational-wave astronomy as a mature field. Upgrades and next-generation detectors will greatly increase detection rates and extend sensitivity across cosmic history, demanding improved waveforms, parameter estimation, and treatment of overlapping signals. The workshop aims to: (1) assess the science reach of ground-based detectors, (2) develop the tools needed to exploit it, and (3) strengthen links between experimental, astrophysical, and theoretical communities.

Week 5 (21st - 27th September): Ultra-High Frequency GW Detectors
Extending gravitational-wave searches above a few kHz may open new probes of extreme matter, the early universe, and dark matter. Current technologies remain far from many target sensitivities, but dedicated searches and new concepts may reveal unexpected signals. The workshop brings together experts in technologies, sources, and data analysis to: (1) review the state of the art, (2) discuss new ideas, and (3) strengthen the growing research community.
