Lattice template placement for coherent all-sky searches for gravitational-wave pulsars

Understand

All-sky, broadband, coherent searches for gravitational-wave pulsars are restricted by limited computational resources.

• Minimizing the number of templates required to cover the search parameter space, of sky position and frequency evolution, is one important way to reduce the computational cost of a search.
• We demonstrate a practical algorithm which, for the first time, achieves template placement with a minimal number of templates for an all-sky search, using the reduced supersky parameter-space metric of Wette and Prix [Phys.
