The Fifth RIT Catalog of Binary Black Hole Simulations: Multiple-Resolution Studies of Eccentric Orbits
Giuseppe Ficarra, James Healy, Carlos O. Lousto
This fifth release of the RIT public catalog of numerical relativity binary black hole waveforms http://ccrg.rit.edu/~RITCatalog introduces an additional 248 configurations, priori…
Ringdown and lensing of triple systems
Vitor Cardoso, Giuseppe Ficarra, Jaime Redondo-Yuste +1
Triple systems have progressively been recognized as ubiquitous in our Universe and provide a good testing ground for wave generation and propagation in nontrivial environments. We…
The Role of Inhomogeneities in the Turbulent Accretion of Black Holes
Giuseppe Ficarra, Michele Arcuri, Rita Megale +1
Observations of supermassive black holes by the Event Horizon Telescope reveal significant inhomogeneities, most likely related to density and magnetic field perturbations. To mode…
Dephasing in binary black hole mergers surrounded by scalar wave dark matter clouds
Cheng-Hsin Cheng, Giuseppe Ficarra, Helvi Witek
Scalar fields of masses between and can exhibit enhanced gravitational interactions with black holes, and form scalar clouds around the…
Measuring the properties of homogeneous turbulence in curved spacetimes
Rita Megale, Alejandro Cruz-Osorio, Giuseppe Ficarra +5
Turbulence in curved spacetimes in general, and in the vicinity of black holes (BHs) in particular, represents a poorly understood phenomenon that is often analysed employing techn…
Parameter Estimation with Targeted Eccentric Numerical-Relativity Simulations for GW200208_22 and GW190620
Patricia McMillin, Katelyn J. Wagner, Giuseppe Ficarra +2
We have analyzed LVK gravitational wave events that show some evidence of eccentricity from TEOBResumS modeling parameter estimations and have confronted them independently with fu…
Eccentric Binary Black Hole Simulations with Numerical Relativity
Giuseppe Ficarra, Carlos O. Lousto
We perform a systematic study of eccentric orbiting nonspinning black hole binaries. We first make a technical study of the optimal full numerical techniques to apply to these stud…
Close Encounter of Three Black Holes III
Giuseppe Ficarra, Carlos O. Lousto
We revisit the three black hole scenario with numerical relativity techniques to study hierarchical configurations where the inner binary contains highly spinning black holes. We f…
Close Encounter of Three Black Holes Revisited
A. Ciarfella, G. Ficarra, C. O. Lousto
We study the evolution of close triple black hole system with full numerical relativity techniques. We consider an equal mass non spinning hierarchical system with an inner binary…
