Introduction

The Spectral Einstein Code (SpEC) is a flexible infrastructure for solving partial differential equations using multi-domain spectral methods. While SpEC was primarily designed for fully general-relativistic compact object simulations, it can be applied to a wide range of hyperbolic and elliptic equations. Some of its features are:

Binary black holes at t=33 Binary black holes at t=7920 Binary black holes at t=8200 Binary black holes at t=9000

SpEC simulation of inspiral and merger of two black holes

The main application area of SpEC lies in simulating compact binary objects. Specifically, it is one of the most accurate and efficient codes to compute the gravitational waveforms for inspiraling and coalescing binary black holes.

Contributors

SpEC was originally developed by Lawrence Kidder, Harald Pfeiffer, and Mark Scheel, who remain the principal maintainers of the code. Since then, many further individuals have contributed to SpEC. Most especially, Matthew Duez and Francois Foucart have developed the hydrodynamics module; Béla Szilágyi and Dan Hemberger have made numerous valuable additions throughout the code; and Lee Lindblom has contributed significantly to the algorithms used in SpEC.

The following researchers have substantially contributed to SpEC: Andy Bohn, Michael Boyle, Luisa Buchman, M. Brett Deaton, Nils Deppe, Roland Haas, Francois Hebert, Kate Henriksson, Stephen Lau, Geoffrey Lovelace, Curran Muhlberger, Sergei Ossokine, Rob Owen, Saul Teukolsky, and Will Throwe.

Further contributions to SpEC were made by Kevin Barkett, Thomas Baumgarte, Jonathan Blackman, Wyatt Brege, Jeandrew Brink, Tony Chu, Michael Cohen, Gregory Cook, Matt Giesler, Jason Grigsby, Casey Handmer, Frank Herrmann, Ian Hinder, Jeff Kaplan, Prayush Kumar, Adam Lewis, François Limousin, Jonas Lippuner, Keith Matthews, Abdul Mroué, Lydia Nevin, Maria Okounkova, David Radice, Oliver Rinne, Olivier Sarbach, Deirdre Shoemaker, Leo C. Stein, Nick Tacik, Nick Taylor, Manuel Tiglio, Anil Zenginoglu, Fan Zhang, and Aaron Zimmerman.
