General Information:

The 2023 North American Einstein Toolkit School and Workshop will be held at the Rochester Institute of Technology on July 17 through July  21. This will be a hybrid conference with talks and participants both  in-person and over zoom. Please scroll down for registration and and other logistics for both in-person and online participants.

The Einstein Toolkit is a community-driven software platform of core  computational tools to advance and support research in relativistic  astrophysics and gravitational physics. The conference consist of a  mixture of tutorials for new users and talks about the latest  developments both in the toolkit and the larger scientific community.
