Event Overview

The goal of this meeting is to bring together theoreticians, modelers, and observers to discuss the challenges and identify promising paths forward for the next generation of observatories, focusing on the next generation Very Large Array (ngVLA). The formation of planetary systems, the evolution of galaxies, and the observation of electromagnetic counterparts of gravitational wave events will be fertile grounds for discovery in the next decades and are core science goals for the ngVLA. The challenge to simulators is to develop predictive models that can be accurately compared against observations, while observers need to generate measurements that can effectively constrain the models. What are the key observables that will allow us to disentangle evolutionary processes and formation and generation mechanisms? What is needed to improve the current generation of theories and models, in order to produce accurate predictions of observable parameters? What types of observational capabilities and programs will be needed to constrain the theories? What are the computational and data challenges, and how can they be overcome?

This meeting will take place for three days at the Simons Foundation's Flatiron Institute in Manhattan, New York. We particularly encourage the participation of early career scientists. The meeting will be in person, but talks will be recorded and made widely available. It will be structured to stimulate dynamic, real-time interactions concerning model development and identification of future observations.
