Scientific Machine Learning for Gravitational Wave Astronomy, June 2-6, 2025 in Providence, Rhode Island

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.

Unlocking Gravity Through Computation, December 9-11, 2024 in Prague

General relativity is a beautiful, but highly complex theory in terms of its field content, invariant structure and the nature of its dynamical equations. Describing gravitational phenomena beyond a weak-field regime and in the absence of global symmetries requires refined computational methods. Progress in understanding black hole properties, binary systems, the early universe, and astrophysical environments depends critically on further developing our computational tool box.

Unlocking Gravity Through Computation will bring together gravity researchers from different backgrounds. We are delighted to be hosting a broad range of keynote speakers working at the forefront of developing and applying numerical approximation and simulation techniques, as well as new analytical methods. We aim for a constructive and interactive meeting, including discussions on the future challenges and opportunities for computation in classical and quantum gravity. We invite the submission of abstracts for contributed talks and posters and encourage especially junior researchers to participate.

KITP rapid response workshop on the GWB, November 12-22, 2024, Santa Barbara

Gravitational Wave Background Found in Pulsar Timing Arrays: Implications for Merging Supermassive Black Holes

Coordinators: Luke Kelley, Chiara Mingarelli, and Gabi Sato-Polito

The recent observation of nanohertz gravitational waves by Pulsar Timing Arrays (PTAs) has opened a new observational window into the universe. Although the origin of the signal has yet to be determined, the measured gravitational-wave background may be produced by a collection of in-spiralling supermassive black holes (SMBHs) or by physics beyond the standard model. The evidence for this background therefore offers unique insights into the astrophysics of SMBHs and potentially new physics. This Rapid Response Workshop will solely focus on the scientific implications for SMBHs of this first PTA detection bringing together experts on both theory and observations.
