On this page we highlight some particularly interesting simulations, though this is by no means a complete list.

The 15-orbit inspiral waveform presented in the paper Boyle et al., Phys Rev. D 76, 124038 (2007) can be found in this file.

This is an ordinary text file containing \(r*m*\Psi_4^{22}\) versus (retarded) time. Here \(r\) is the radius, \(m\) is the total irreducible mass as defined in our paper, and \(\Psi_4^{22}\) is the \(l=2\), \(m=2\) component of the Newman-Penrose quantity \(\Psi_4\) as measured by an observer at infinity. This is the highest-quality extrapolated-to-infinity numerical waveform underlying all our results in Section VI of the paper. The file contains some comments at the top (starting with a '#' character), and then three columns of numbers. If we write \(r*m*\Psi_4^{22} = A^{-i \phi}\), then the columns in the file are \(\frac{t-r^\star}{m}\), \(\phi\), and \(A\). The overall phase offset and time offset are arbitrary.

Permission to use this waveform is granted as long as the user acknowleges the source of the waveform and cites the paper Boyle et al., Phys Rev. D 76, 124038 (2007). (This paper can also be found here.)

The 16-orbit Psi4 waveform for a zero-spin equal mass binary, as presented in the paper Scheel et al., Phys Rev. D 79, 024003 (2009) can be found in this file.

This is an ordinary text file containing \(r*m*\Psi_4^{22}\) versus (retarded) time. Here \(r\) is the radius, \(m\) is the total initial irreducible mass as defined in our paper, and \(\Psi_4^{22}\) is the \(l=2\), \(m=2\) component of the Newman-Penrose quantity \(\Psi_4\) as measured by an observer at infinity. The file contains some comments at the top (starting with a '#' character), and then three columns of numbers:\(\frac{t-r^\star}{m}\), \(Re(r*m*\Psi_4^{22})\), and \(Im(r*m*\Psi_4^{22})\). The overall time shift and phase shift are arbitrary. This waveform corresponds to the highest-resolution (30c/N6 in the paper) \(\Psi_4\) waveform, extrapolated to infinity (using extrapolation order \(n=3\)). This is the same waveform shown in Fig. 11 in the paper.

Permission to use this waveform is granted as long as the user acknowleges the source of the waveform and cites the paper Scheel et al., Phys Rev. D 79, 024003 (2009) (This paper can also be found here).

The SXS project is a collaborative research effort involving multiple institutions. Our goal is the simulation of black holes and other extreme spacetimes to gain a better understanding of Relativity, and the physics of exotic objects in the distant cosmos.

The SXS project is supported by Canada Research Chairs, CFI, CIfAR, Compute Canada, Max Planck Society, NASA, NSERC, the NSF, Ontario MEDI, the Sherman Fairchild Foundation, and XSEDE.
