Organizing Committee
Abstract

A new era of astronomical observation was announced in 2016 when the first-ever detection of gravitational waves from a binary black hole system occurred. Gravitational waves encode detailed information about the astrophysical systems they emerge from and complement what can be learned through traditional light-based observation.

Gravitational wave science requires high-fidelity numerical simulations of the expected merger events. The Simulating eXtreme Spacetimes (SXS) collaboration has managed the development of two distinct codes for this purpose: (i) the Spectral Einstein Code (SpEC) based on pseudospectral methods, and (ii) an open-source code SpECTRE, an hp-adaptive discontinuous Galerkin scheme that also includes a sub-cell finite volume scheme in regions of strong shock formation that is ideally suited for multi-scale, multi-physics problems. SpECTRE targets problems in multi-messenger astrophysics, including neutron star mergers, core-collapse supernovae, and gamma-ray bursts. It runs at petascale and is designed for future exascale computers.

Our weeklong program includes two contemporaneous activities: (i) a focused SpEC and SpECTRE code developers meeting and (ii) a SpECTRE workshop. The code developers' meeting will bring together researchers who are actively developing these codebases. The SpECTRE workshop aims to provide graduate students, postdocs, and faculty with the tools needed to install, run, and contribute to the open-source code SpECTRE. Our SpECTRE workshop will cover topics such as the generalized harmonic formulation of the Einstein field equation, general relativistic hydrodynamics, the discontinuous Galerkin method with finite volume sub-cells, the Cauchy characteristic extraction method, installing, running, and visualizing numerical simulations, and how to get involved with code development.

Projects

SpECTRE Community Workshop

Group Leaders TBA

The open-source code SpECTRE is a relativistic astrophysics code for simulating neutron star mergers, core-collapse supernovae, and gamma-ray bursts. Our 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 hand-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. There will also be ample opportunity for students and postdocs to interact with senior participants and lecturers of the ICERM workshop program.

As part of your application to the SpECTRE summer school, please briefly answer the following questions in your personal statement:

1. How does your research involve numerical relativity and/or relativistic astrophysics? 2. Do you have experience in computational physics and/or numerical relativity? Which, if any, numerical relativity codebases have you interacted with? (Note that previous experience is not required to attend the workshop.)

SXS developer meeting

Group Leaders TBA

The Simulating eXtreme Spacetimes (SXS) collaboration has overseen the development of two distinct codes — namely, the Spectral Einstein Code (SpEC) and SpECTRE — alongside the development of public simulation datasets and accompanying software for data interaction. Our upcoming in-person developers' workshop will serve as a focused forum for these codes as well as welcoming other researchers eager to contribute to these projects.

To apply for participation in the developer's meeting, please address the following questions in your personal statement:

1. Share your prior experience in developing SpEC, SpECTRE, or codes/datasets derived from simulation outputs. If you lack prior exposure to these codes, please highlight your experience with other computational relativity codes. 2. Identify the development tasks that most pique your interest for discussion or collaboration during this meeting.
