R-mode frequencies of rapidly and differentially rotating relativistic neutron stars
Michael Jasiulek, Cecilia Chirenti
R-modes of neutron stars could be a source of gravitational waves for ground based detectors. If the precise frequency is known, guided gravitational wave searches with enhance…
Isometric embeddings of 2-spheres by embedding flow for applications in numerical relativity
Michael Jasiulek, Mikolaj Korzynski
We present a numerical method for solving Weyl's embedding problem which consists of finding a global isometric embedding of a positively curved and positive-definite spherical 2-m…
Hyperboloidal slices for the wave equation of Kerr-Schild metrics and numerical applications
Michael Jasiulek
We present new results from two open source codes, using finite differencing and pseudo-spectral methods for the wave equations in (3+1) dimensions. We use a hyperboloidal transfor…
The slicing dependence of non-spherically symmetric quasi-local horizons in Vaidya Spacetimes
Alex B. Nielsen, Michael Jasiulek, Badri Krishnan +1
It is well known that quasi-local black hole horizons depend on the choice of a time coordinate in a spacetime. This has implications for notions such as the surface of the black h…
A new method to compute quasi-local spin and other invariants on marginally trapped surfaces
Michael Jasiulek
We accurately compute the scalar 2-curvature, the Weyl scalars, associated quasi-local spin, mass and higher multipole moments on marginally trapped surfaces in numerical 3+1 simul…
