Dear Numerical Relativists,

This is a quick reminder that applications for our SpECTRE community workshop, Aug 5–9, 2024, at ICERM, Brown University, US, are due on Mar 20 (next Wednesday). You can find the full announcement of the workshop below. Please consider joining us for the workshop, and feel free to reach out if you have any questions.

Best, Nils

—

Applications are now open for an upcoming workshop "Simulating Extreme Spacetimes with SpEC and SpECTRE", Aug 5-9, 2024, at ICERM, Brown University, US.

The Simulating eXtreme Spacetimes (SXS) collaboration has managed the development of two distinct numerical relativity codes to enable high-fidelity simulations of compact object mergers: (i) the Spectral Einstein Code (SpEC) based on pseudospectral methods, and (ii) the open-source code SpECTRE, an hp-adaptive discontinuous Galerkin scheme for relativistic astrophysics.

Our weeklong program includes two related activities: (i) a SpEC and SpECTRE developers meeting and (ii) a SpECTRE community workshop.

The code developers' meeting will bring together researchers who are actively developing SpEC, SpECTRE, and accompanying software for interacting with publicly available simulation datasets such as gravitational waveforms.

The SpECTRE workshop aims to provide graduate students, postdocs, and faculty with the tools to install, run, and contribute to the open-source code SpECTRE. Our SpECTRE workshop will include both lectures and hands-on sessions. Lecture topics will include the generalized harmonic formulation of the Einstein field equation, general relativistic hydrodynamics, the discontinuous Galerkin method with finite volume sub-cells, and the Cauchy characteristic extraction method. Hands-on sessions will cover installing, running, and visualizing numerical simulations, and how to get involved with code development. There will also be ample opportunity for students and postdocs to interact with senior participants and lecturers of the ICERM workshop program.

Both events will be in-person, with streaming options available for lectures. ICERM will be able to offer limited funding for some participants.

The application deadline is March 20, 2024. Please apply here: https://icerm.brown.edu/topical_workshops/tw-24-ses/
