Binary Black Hole Waveforms from High-Resolution GR-Athena++ Simulations

Alireza Rashti, Rossella Gamba, Koustav Chandra +4

The detection and subsequent inference of binary black hole signals rely heavily on the accuracy of the waveform model employed. In the highly non-linear, dynamic, and strong-field…

Spin the black circle: horizon absorption on non-circular, planar binary black hole dynamics

Danilo Chiaramello, Rossella Gamba

Binary systems of black holes emit gravitational waves as they move through their orbits. While most of the emitted radiation escapes to future null infinity, a small fraction is a…

Effective-one-body waveform model for noncircularized, planar, coalescing black hole binaries II:high accuracy by improving logarithmic terms in resummations

Alessandro Nagar, Danilo Chiaramello, Rossella Gamba +5

Effective-one-body (EOB) models are based on analytical building blocks that, mathematically, are truncated Taylor series with logarithms. These functions are usually resummed usin…

Scattering and dynamical capture of two black holes: synergies between numerical and analytical methods

Simone Albanesi, Alireza Rashti, Francesco Zappa +6

We study initially unbound systems of two black holes using numerical relativity (NR) simulations performed with GR-Athena++. We focus on regions of the parameter space close to th…

Towards efficient Effective One Body models for generic, non-planar orbits

Rossella Gamba, Danilo Chiaramello, Sayan Neogi

Complete waveform models able to account for arbitrary non-planar orbits represent a holy grail in current gravitational-wave astronomy. Here, we take a step towards this direction…

Effective-one-body waveform model for non-circularized, planar, coalescing black hole binaries: the importance of radiation reaction

Alessandro Nagar, Rossella Gamba, Piero Rettegno +2

We present an updated version of the TEOBResumS-Dali effective-one-body (EOB) waveform model for spin aligned binaries on non-circularized orbits. Recently computed 4PN (nonspinnin…
