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…
Everything everywhere all at once: A detailed study of GW230529
Koustav Chandra, Ish Gupta, Rossella Gamba +5
This study investigates the origins of GW230529, delving into its formation from massive stars within isolated binary systems. Utilizing population synthesis models, we present com…
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…
