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.

Workshop Website

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 are two-fold:

• Connect LISA data scientists with astronomers and astrophysicists who will incorporate LISA data products into their research.
• Advance the research community’s readiness to capitalize on LISA observations.

Workshop Theme

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 to make concrete progress on concise projects and goals related to this scientific area.

Participants are encouraged to propose ideas and contribute material that aligns with the workshop’s format. This is a hands-on workshop with no traditional talks—only brief project pitches and a final “show and tell” to share progress with the group.

Logistics

Information for planning your trip will be available soon. Stay tuned for more details on travel, accommodation, and venue information.

Who Should Attend?

This workshop is ideal for researchers, astronomers, astrophysicists, and data scientists who wish to engage with LISA’s data and contribute to the future of gravitational wave astronomy.

Meeting Website

The aim of this workshop is to 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 areas of focus will be: (i) noise classification and detection, (ii) waveform modeling and uncertainty quantification, and (iii) source parameter and astrophysical population Bayesian inference.

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.
