Searches For Gravitational Waves From Binary Black Hole Coalescences With Ground-based Laser Interferometers Across a Wide Parameter Space
Binary Black Hole Data Analysis Gravitational-Waves LIGO NINJA Signal Processing
2014/11/20
This is an exciting time for Gravitational Wave (GW) theory and observations. From a theoretical standpoint, the grand-challenge problem of the full evolution of a Binary Black Hole (BBH) system has b...

Comparing space+time decompositions the post-Newtonian limit

We compare the Arnowitt-Deser-Misner (ADM) field decomposition with the Non-Relativistic Gravitational (NRG) fields for the purpose of computing the two-body post-Newtonian (PN) effective action withi...
Space-Time Compactification, Non-Singular Black Holes, Wormholes and Braneworlds via Lightlike Branes
Space-Time Compactification Non-Singular Black Holes

We describe a concise general scheme for constructing solutions of Einstein-Maxwell-Kalb-Ramond gravity-matter system in bulk space-time interacting self-consistently with one or more (widely separate...
An analogue of the Newton-Wigner position operator is defined for a massive neutral scalar field in de Sitter space. The one-particle subspace of the theory, consisting of positive-energy solutions of...
Strings in Flat Space and Plane Waves from N = 4 Super Yang Mills
Strings Flat Space Plane Waves N = 4 Super Yang Mills
2010/10/18
We explain how the string spectrum in flat space and plane waves arises from the large N limit of U(N) N = 4 super Yang Mills. We reproduce the spectrum by summing a subset of the planar Feynman diagr...
