The Dawn of Gravitational Wave Cosmology, April 28 – May 17 2025, Benasque

Starting at its very origin, the universe is awash with mechanisms for gravitational wave (GW) production. The upcoming launch of an unprecedented array of gravitational wave missions, capable of testing more than 20 decades in frequencies, will usher in the era of gravitational wave cosmology and open up a new window on fundamental physics. It is thus more timely than ever for the physics community to identify priorities and coordinate the efforts in the field.

It is fair to say theory has not yet fully caught up with experiments and that a theory-to-data pipeline ought to be built to maximize and amplify the discovery potential of GW probes. There is more: the sheer number and range of forthcoming probes call for a truly multi-messenger approach to cosmology.

The Benasque Program is the ideal setting to:
(i) put together experts on many different GW probes, from the CMB to large scale structure, from PTAs to laser interferometers. This will enable the community to paint a complete picture of what can be achieved in the coming years, a pursuit that will not be complete without a strong focus on (ii) the possibility of cross-correlating different probes. One key aspect of cross-correlations is indeed their ability to disentangle the primordial from the astrophysical GW signal. This is central to the success of the entire field of GW cosmology.

Benasque is the beautiful town on the Spanish Pyrenees where the ‘Pedro Pascual’ Science Center (https://www.benasque.org/) is located.

Ten Years to LISA: New Challenges and Opportunities in Multimessenger/Multiband Science, April 1-3, 2025, hybrid

The conference website for Ten Years to LISA: New Challenges and Opportunities in Multimessenger/Multiband Science is now online.
This is a hybrid meeting, meaning participation can be virtual or in-Person. Dates: April 1-3, 2025. In-Person Location: von Karman Auditorium, Jet Propulsion Laboratory, Pasadena, CA

Conference Overview: Motivation and Format

For the purpose of this Overview, “multimessenger astronomy” stands for “multimessenger including gravitational waves”, and “multiband” means “multiple gravitational-wave bands”. Multimessenger astronomy, in this sense, began with a bang with the LIGO-Virgo detection of GWs from the merger of two neutron stars, GW170817, an event that was soon observed in most EM bands. While there was an expectation in the field that NS mergers powered some short gamma-ray bursts (sGRBs) and models of their subsequent radioactive decay (kilonova) existed, confirmation of these theories occurred only from GW170817. Details of these events, like the delay between the GW and GRB signals and the GRB strength, however, led to new insights into their pre-merger environments and the dependence on viewing angle of the jet’s appearance.

Astrophysicists’ predictions of the EM signals that will accompany LISA (Laser Interferometer Space Antenna) events may be even less advanced than sGRB models prior to GW170817 and share a lack of confirming evidence. This conference is premised on the viewpoint that this relative ignorance represents an opportunity, or, really, several opportunities. There is important work to be done i) using past and upcoming observations (both EM and GW) to constrain event rates and search for the signatures of LISA-type events before LISA turns on; and ii) using astrophysical models to predict the multimessenger and multiband signals that will accompany LISA signals.

We have about ten years to work on this before LISA and Nature start to give us some of the answers. It is our belief that such work done before LISA starts taking data will almost surely help us maximize the science we extract. (And we expect that will be true even if most of our predictions are not ultimately borne out by observations.)

With the above as motivation, this Conference will give overviews of the sorts of EM & GW observations that we expect to be made over the next 10+ years and how they relate to LISA. And it will suggest LISA multimessenger/multiband science investigations that could be started now. Our main goal is to help stimulate new, important work in these areas.

The format for the conference is as follows. We have divided our subject into eight topics. Over the course of the three-day conference, there will be eight sessions: one devoted to each topic. For each session, we have found a topical expert who has agreed to chair that session. The Session Chairs will build their sessions using some combination of invited talks and talks contributed via this website. It will be up to each Session Chair to construct their session as they think best.

This a hybrid conference, meaning participation can be either in-person or online. There is zero registration fee for either in-person or remote attendance. However, we recommend that you attend in person, if you can, to benefit from the side discussions that are important part of any conference. We plan to limit talks to about six hours per day, to leave plenty of time for such side discussions.

Important Dates:

  • Monday, December 23, 2025 – Registration open
  • Tuesday, February 4, 2025 – Deadline for abstract submission for presentations and posters
  • Monday, February 24, 2025 – Registration closes for attendees from these Designated Countries who are attending in person
