Gauge-invariant perturbations of Schwarzschild spacetime
Abhay G. Shah, Bernard F. Whiting, Steffen Aksteiner +2
We study perturbations of Schwarzschild spacetime in a coordinate-free, covariant form. The GHP formulation, having the advantage of not only being covariant but also tetrad-rotati…
Gauge Invariant Perturbations of the Schwarzschild Spacetime
Jonathan E. Thompson, Hector Chen, Bernard F. Whiting
Beginning with the pioneering work of Regge and Wheeler (Phys. Rev. 108, 1957), there have been many studies of perturbations away from the Schwarzschild spacetime background. In p…
Optimal Surface Segmentation with Convex Priors in Irregularly Sampled Space
Abhay Shah, Michael D. Abramoff, Xiaodong Wu
Optimal surface segmentation is a state-of-the-art method used for segmentation of multiple globally optimal surfaces in volumetric datasets. The method is widely used in numerous…
iResum: a new paradigm for resumming gravitational wave amplitudes
Alessandro Nagar, Abhay G. Shah
We introduce a new, resummed, analytical form of the post-Newtonian (PN), factorized, multipolar amplitude corrections of the effective-one-body (EOB) gravitational wa…
