Black-hole binary inspiral: a precession-averaged approach

Check me out on github.com/dgerosa/spinprecession.

This page contains data supporting some of our papers on black-hole binary spin precession. Most of these results are obtained with the public precession code. In particular, we provide animated versions of some of the figures from:

  • Residual eccentricity as a systematic uncertainty on the formation channels of binary black holes. Giulia Fumagalli, Isobel Romero-Shaw, Davide Gerosa, Viola De Renzis, Konstantinos Kritos, Aleksandra Olejak. arXiv:2405.soon.

  • Up-down instability of binary black holes in numerical relativity. Vijay Varma, Matthew Mould, Davide Gerosa, Mark A. Scheel, Lawrence E. Kidder, and Harald P. Pfeiffer. Phys. Rev. D 103 (2021) 064003. arXiv:2012.07147.

  • Endpoint of the up-down instability in precessing binary black holes. Matthew Mould, Davide Gerosa. Phys.Rev.D 101 (2020) 124037.  arXiv:2003.02281.

  • Wide precession: binary black-hole spins repeatedly oscillating from full alignment to full anti-alignment. Davide Gerosa, Alicia Lima, Emanuele Berti, Ulrich Sperhake, Michael Kesden, Richard O'Shaughnessy. Class. Quant. Grav. 36 (2019) 105003. arXiv:1811.05979.

  • Surprises from the spins: astrophysics and relativity with detections of spinning black-hole mergers. Davide Gerosa. Journal of Physics: Conf. Series 957 (2018) 012014. arXiv:1711.10038.

  • Precessional instability in binary black holes with aligned spins. Davide Gerosa, Michael Kesden, Richard O'Shaughnessy, Antoine Klein, Emanuele Berti, Ulrich Sperhake, Daniele Trifirò. Phys. Rev. Lett. 115 (2015) arXiv:1506.09116.

  • A multi-timescale analysis of phase transitions in precessing black-hole binaries. Michael Kesden, Davide Gerosa, Ulrich Sperhake, Emanuele Berti, Richard O'Shaughnessy. Phys. Rev. D 92 (2015) 064016. arXiv:1506.03492.

  • Effective potentials and morphological transitions for binary black-hole spin precession. Davide Gerosa, Michael Kesden, Richard O'Shaughnessy, Emanuele Berti, Ulrich Sperhake. Phys. Rev. Lett. 114 (2015) 081103. arXiv:1411.0674.

Figures published in the papers are snapshots (at fixed binary separation) of these animations. References to other figures and equations in the captions correspond to those in the relevant paper. Here is a Youtube playlist containing all animations.

We also provide older animated gif from:

  • Resonant-plane locking and spin alignment in stellar-mass black-hole binaries: a diagnostic of compact-binary formation. Davide Gerosa, Michael Kesden, Emanuele Berti, Richard O’Shaughnessy, Ulrich Sperhake. Phys. Rev. D 87 (2013) 104028. arXiv:1302.4442.

  • Spin alignment effects in black hole binaries. Davide Gerosa. Caltech Undergraduate Research Journal (CURJ) Vol.15 No.1 (2014).


You are more than welcome to use these results in your presentations! We kindly ask you to cite the relevant papers. If you want to cite the animations specifically, it's DOI.
