Solvay workshop on “Gravitational Wave Cosmology” 19-21 February 2025

(posted here January 17, 2025)

Dear colleagues,

We are pleased to announce the Solvay workshop on “Gravitational Wave Cosmology”, which will take place at ULB on the 19-21 February 2025.

This workshop aims to provide insights on pressing questions that new observations are currently bringing such as:

• How can we distinguish cosmological sources from the detected Pulsar Timing Array signal ?

• What is the nature of the Hubble tension: systematic errors or a sign for new physics?

• How will gravitational waves standard sirens contribute in the near future?

• How to distinguish the primordial gravitational wave background from the astrophysical background?

• Which notable multi-messenger signatures should be searched for ?

Registration is open on http://www.solvayinstitutes.be/event/workshop/gravitational_wave_2025/gravitational_wave_2025.html

We hope to see you at this exciting workshop!

Warm regards,

On behalf of the organising committee, Giacomo Bruno, Sébastien Clesse, Geoffrey Compère, Archisman Ghosh, Alberto Marrioti, Samaya Nissanke, Nick Van Remortel, Alex Sevrin

Dear colleagues:

We are happy to share that the conference website for Ten Years to LISA: New Challenges and Opportunities in Multimessenger/Multiband Science is now online at
https://science.jpl.nasa.gov/workshops/LISA.

You can go there now to register and/or submit an abstract. As the meeting title indicates, the conference will mostly focus on multi-messenger/multiband science connected to LISA. Within this general area, it will emphasize EM & GW observations that will be made over the next ~10-15 years and how they relate to LISA, and it will suggest LISA multimessenger/multiband science investigations that could be started now.

The scientific program will be divided into eight Sessions. Each Session will have its own Session Chair, who will beresponsible for planning that Session’s program. We are pleased to announce our Sessions and Session Chairs:

- EM Telescopes and Observations from now to 2040, Daniel Stern
- Gravitational-Wave Telescopes and Observations from now to 2040, David Shoemaker
- Galactic binaries, Kevin Burdge

Aspen Summer 2025: Physics in the Era of Nanohertz Gravitational Waves

(posted here January 03, 2025)

Dear colleagues,

We are excited to announce that our 2025 summer Aspen workshop proposal for "Physics in the Era of Nanohertz Gravitational Waves" has been accepted and applications are now open.

The program is scheduled for August 3-24, 2025. The application deadline is January 31, 2025; see https://aspenphys.org/summer-workshops/. We invite you to apply. Please also encourage other people who are active in the field to apply.

Be aware that we cannot guarantee admission to the workshop. Admission to the workshop is granted not by the workshop organizers, but by the Admissions Committee of the Center. Because of the constraints imposed by the rest of the Aspen Center for Physics program, they are usually not able to admit everyone who applies.

Aspen Center for Physics encourages participants, especially those early in their careers, those with families, and those from underrepresented groups, institutions, and countries, to apply for our summer program. The Center has a limited amount of additional financial support for participants who fall into these, and other, special categories and encourages applicants who need financial support to apply for it on their application.

Best,

Kimberly Boddy

11th Gulf Coast Gravity Meeting

(posted here December 20, 2024)

The GCGM returns to the University of Mississippi! The 11th Gulf Coast Gravity Meeting will be held at the University of Mississippi in Oxford, MS, on April 11 and 12, 2025. In keeping with its tradition, this will be an open, relaxed, and informal conference. We are inviting researchers and students interested in all areas of gravitational physics: classical and quantum gravity, general relativistic astrophysics and cosmology, quantum cosmology, gravitational waves, and experimental gravity. Because this is a regional meeting, many attendees will be from the southeastern United States, but all are welcome.

Talks

Following the usual tradition all participants, and especially postdocs and graduate students, are encouraged to contribute short, introductory talks on their current research, with the aim of fostering communication and understanding among gravitational physicists with different backgrounds. A prize (sponsored by the APS Division of Gravitational Physics) will be awarded for the best talk given by a student at the meeting.

Deadlines

Prospective speakers should register by March 01 to receive full consideration. Late applicants will be considered at the discretion of the organizers. See the website for details: https://www.phy.olemiss.edu/gcgm11/.

Announcing the 3rd LISA Sprint

(posted here December 20, 2024)

The Laser Interferometer Space Antenna (LISA) is a joint effort of ESA and NASA to develop and operate the first space-based observatory of gravitational waves (GWs) in the millihertz frequency band. To prepare for LISA observations and its unique data products, we are organizing the 3rd LISA Sprint in Huntsville, AL, from Monday April 28 to Wednesday April 30, 2025.

The meeting's goals will be two-fold: The first goal is to connect LISA data scientists with astronomers and astrophysicists who will incorporate LISA data products into their own research. The second is to advance the broader research community’s readiness to capitalize on LISA observations.

The theme for this third meeting is Time Domain and Multimessenger Astronomy with LISA. During the workshop small interdisciplinary teams of researchers will come together and make concrete progress on concise projects and goals related to this scientific area. A number of project ideas and mock data and/or data products will be produced and provided by the organizers in collaboration with experts in the field. Additionally, participants are encouraged to propose ideas and contribute further material that adheres to the workshop’s format.

This will be a hands-on workshop: there will be no talks--only brief project “pitches” at the beginning of the workshop, and “show and tell” at the close of the meeting to share progress with the group.

In early January 2025 we will advertise the meeting website and application form for interested participants. Please note that space will be limited, so applying does not guarantee acceptance. Accepted applicants will be notified by the end of February. There is no financial support available to attend the meeting, nor is there any registration fee for participating.

Workshop on Scientific Machine Learning for Gravitational Wave Astronomy at ICERM

(posted here Novemeber 08, 2024)

​We are pleased to announce a workshop on Scientific Machine Learning for Gravitational Wave Astronomy which will be held at the Institute for Computational and Experimental Research in Mathematics (ICERM) in Providence, RI, June 2-6, 2025. Applications are open at https://icerm.brown.edu/program/topical_workshop/tw-25-smlgwa.

​The workshop will bring together participants from computational mathematics and gravitational wave astronomy to tackle computational challenges in leveraging data-driven methods in key areas of gravitational wave data analysis in order to maximize the science output of the ongoing and upcoming observations.

The participants will develop and apply new mathematical and computational techniques including: (i) neural network classifiers for distinguishing signals from instrumental noise, (ii) generative machine learning models for simulating realizations of non-Gaussian and non-stationary stochastic processes, (iii) surrogate models including uncertainty quantification, (iv) stochastic sampling, neural posterior estimation leveraging deep neural networks with normalizing flows or diffusion models, and (v) hierarchical Bayesian inference with non-parametric models such as Gaussian processes and simulation-based / approximate Bayesian approaches.

While the application window will be open until all slots are filled, we recommend applying by December 15.

​The workshop will be in-person, with streaming options available for lectures.

​ICERM will be able to offer limited funding for some participants, so apply early for best chance at this funding!

With warm regards,

Sarah Caudill, Katerina Chatziioannou, Maya Fishbach, Brendan Keith, Jess McIver, Michael Puerrer, Joshua Speagle, and Vijay Varma
