Numerical relativity has faced the problem that standard 3+1 simulations of black hole spacetimes without singularity excision and with singularity avoiding lapse and vanishing shift fail after an evolution time of around 30-40M due to the so-called slice stretching. We discuss lapse and shift conditions for the non-excision case that effectively cure slice stretching and allow run times of 1000M and more.

  1. Cuspidal Singularities in Collapsing Domain Walls

    hep-th 2026-05 conditional novelty 7.0

    Collapsing domain walls generically form cuspidal edge and vertex singularities captured by Nambu-Goto and eikonal approximations and reproduced in field theory simulations.

  2. The third wheel: ringdown and lensing of triple systems

    gr-qc 2026-05 unverdicted novelty 6.0

    Numerical relativity simulations of triple black hole systems reveal redshift effects and gravitational lensing in ringdown signals from head-on mergers, with no additional black hole formation from amplified waves.

  3. Nucleosynthesis in the fast ejecta of a neutron star merger

    astro-ph.HE 2026-05 unverdicted novelty 5.0

    Free neutrons survive r-process freeze-out in fast ejecta of neutron star mergers and their beta-decay heating produces a visible early kilonova precursor for mass fractions above ~0.05.
