Superposed metric for spinning black hole binaries approaching merger
Luciano Combi, Federico G. Lopez Armengol, Manuela Campanelli +4
We construct an approximate metric that represents the spacetime of spinning binary black holes (BBH) approaching merger. We build the metric as an analytical superposition of two…
Circumbinary Disk Accretion into Spinning Black Hole Binaries
Federico G. Lopez Armengol, Luciano Combi, Manuela Campanelli +6
Supermassive black hole binaries are likely to accrete interstellar gas through a circumbinary disk. Shortly before merger, the inner portions of this circumbinary disk are subject…
Hubble Constant Measurement with GW190521 as an Eccentric Black Hole Merger
V. Gayathri, J. Healy, J. Lange +7
Gravitational wave observations can be used to accurately measure the Hubble constant and could help understand the present discrepancy between constraints from Type Ia super…
AstroDance: Engaging Deaf and Hard-of-Hearing Students in Astrophysics via Multimedia Performances
J. Nordhaus, M. Campanelli, J. Bochner +3
The dynamics of gravitating astrophysical systems such as black holes and neutron stars are fascinatingly complex, offer some of nature's most spectacular phenomena, and capture th…
Numerical relativity in spherical coordinates: A new dynamical spacetime and general relativistic MHD evolution framework for the Einstein Toolkit
Vassilios Mewes, Yosef Zlochower, Manuela Campanelli +4
We present SphericalNR, a new framework for the publicly available Einstein Toolkit that numerically solves the Einstein field equations coupled to the equations of general relativ…
PatchworkWave: A Multipatch Infrastructure for Multiphysics/Multiscale/Multiframe/Multimethod Simulations at Arbitrary Order
Dennis B. Bowen, Mark Avara, Vassilios Mewes +6
We present an extension of the PatchworkMHD code [1], itself an MHD-capable extension of the Patchwork code [2], for which several algorithms presented here were co-developed. Its…
