The existence and stability of marginally trapped surfaces
Daniel Pook-Kolb, Ofek Birnholtz, Badri Krishnan +1
Marginally outer trapped surfaces (MOTSs, or marginal surfaces in short) are routinely used in numerical simulations of black hole spacetimes. They are an invaluable tool for locat…
1-OGC: The first open gravitational-wave catalog of binary mergers from analysis of public Advanced LIGO data
Alexander H. Nitz, Collin Capano, Alex B. Nielsen +4
We present the first Open Gravitational-wave Catalog (1-OGC), obtained by using the public data from Advanced LIGO's first observing run to search for compact-object binary mergers…
Reducing the number of templates for aligned-spin compact binary coalescence gravitational wave searches using metric-agnostic template nudging
Nathaniel Indik, Henning Fehrmann, Franz Harke +2
Efficient multi-dimensional template placement is crucial in computationally intensive matched-filtering searches for Gravitational Waves (GWs). Here, we implement the Neighboring…
Dynamics of marginally trapped surfaces in a binary black hole merger: Growth and approach to equilibrium
Anshu Gupta, Badri Krishnan, Alex B. Nielsen +1
The behavior of quasi-local black hole horizons in a binary black hole merger is studied numerically. We compute the horizon multipole moments, fluxes and other quantities on black…
