Dear Einstein Toolkit users,
We are excited to announce the upcoming workshop "Infinity on a Gridshell" https://hyperboloid.al/event/copenhagen-23/, which will take place from *July 10 to July 13, 2023, at the Niels Bohr Institute, University of Copenhagen*. The workshop will focus on the progress made in *hyperboloidal methods*, which have emerged as a crucial tool in black-hole perturbation theory and other diverse applications.
The workshop aims to bring together leading experts to review and summarize the current *state-of-the-art of hyperboloidal methods* in a wide range of applications, including the computation of wave equations, quasi-normal modes, effective-one-body formalism, and self-force. The focus will be on exploring ideas to solve the full Einstein equations for astrophysically relevant scenarios.
We have a *limited number of seats* for researchers to attend the conference in person. Participants will have the opportunity to present their work using hyperboloidal methods, exchange ideas, and discuss the challenges and opportunities in the field. We aim to foster new collaborations and build a community of researchers to connect and engage in productive discussions.
We encourage researchers and graduate students with an interest in hyperboloidal methods to apply for this exciting event. The workshop will provide an excellent opportunity to learn about the latest developments, contribute to the advancement of the field, and to *join the hyperboloidal community*.
For more information about the workshop, please visit our website https://hyperboloid.al/event/copenhagen-23/. A poster is available here https://hyperboloid.al/event/copenhagen-23/poster.webp. You can apply to participate by filling the form at the strong GR website https://strong-gr.com/infinity-on-a-grid-shell/registration/ before the *deadline April 30, 2023*. We look forward to welcoming you to Copenhagen.
