News & Updates

Kate Henriksson and some of her fellow members of the SXS collaboration produced newer and better data for simulations of neutron stars colliding with black holes. Using advanced numerical techniques, the neutron stars they've constructed are the densest ever created, which will lead to some of the most extreme simulations in the world. Check out the preprint here.

Recent Developments

The SXS collaboration has produced a computer code which can simulate the motion of pairs of black holes or neutron stars with very high accuracy, and great computational efficiency. SXS members continue to extract scientific information from the simulations, and use this information to further our understanding of black-hole physics, and to improve techniques for finding the signals in gravitational-wave detector data.

Come, you lost Atoms, to your Centre draw,
And be the Eternal Mirror that you saw:
Rays that have wander'd into Darkness wide,
Return and back into your Sun subside.

About SXS

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.
