NEWS: First GWPFP Bottom-Up Cross-cutting Workshop: 

We are happy to announce the first Bottom-Up Cross-cutting Workshop of the GWPFP initiative, that will take place on February, 12-16 2024 at Sapienza University of Rome. 

This will be the kick-off event that will shape the organization of our cross-cutting initiative and we would like to get all members involved from the very beginning of this effort.

In this spirit, only the main broad topics of the workshop are fixed, which are those discussed in this manifesto. The entire workshop structure and concrete topics will emerge from the bottom up, based on your feedback.

At this stage, your action is needed to organize the event! In order to contribute, please follow these instructions:

  1. Fill this form with your favorite topics/questions related to this action
  2. Even before doing so, please check this outcome file, which lists (live) the topics previously selected. If you find a topic of your interest, you can just add your name in the last column as a comment; there's no need to repeat the entry in the form

After gathering feedback from the community, we will develop the workshop schedule around the topics that have emerged from this survey.

The deadline to contribute is June 18th, 2023.

If you have any questions or comments please feel free to contact us


The landmark detection of gravitational waves (GWs) emitted by black-hole and neutron-star binaries has opened a new era in physics, giving access to hitherto unexplored systems. In parallel to their countless astrophysical applications, these discoveries open new avenues to explore fundamental physics. 

  • WP1: Matter under extreme conditions
  • WP2: Nuclear and atomic physics and their role in multi-messenger astronomy
  • WP3: Fundamental problems in high-energy and gravitational physics
  • WP4: GWs & Cosmology
  • WP5: Synergies between particle accelerators and GWs

Attacking these grand problems requires a multidisciplinary, cross-cutting effort at the interface of different communities. Recently, specific initiatives to connect affine subareas (e.g. nuclear and GW astrophysics or black-hole and particle physics) were established, but lack the required depth and stability. We propose to support and train the next generation of leaders in GW physics, who will be able to communicate across a spectrum of sub-fields. This is instrumental to maximize the benefit from theoretical developments and from the wealth of data, now available from current (LIGO/Virgo/KAGRA) and soon to be taken by future (LISA, Einstein Telescope, Cosmic Explorer) GW interferometers, radio and X-ray observatories (e.g., Event Horizon Telescope, NICER, GRAVITY, Athena, eXTP), and from particle accelerators facilities (e.g., CERN, GSI/FAIR).
