Gravitational Wave Hyperbolic Catalog: Reanalyzing High-Mass Gravitational Wave Signals Using Hyperbolic Waveforms
Jacob Lange, Danilo Chiaramello, Peter Lott +4
Close hyperbolic encounters between black holes produce distinctive bursts of gravitational radiation with a time-frequency morphology that is qualitatively different from that of…
Spin the black circle II: tidal heating and torquing of a rotating black hole by a test mass on generic orbits
Rossella Gamba, Danilo Chiaramello, Estuti Shukla +1
Horizon fluxes of energy and angular momentum are a key strong-field effect in the dynamics of black holes, encoding direct information about their nature. In this work, we present…
From Source Properties to Strong-Field Tests: a multipronged analysis of GW250114 with an effective one-body model for generic orbits
Koustav Chandra, Rossella Gamba, Danilo Chiaramello
We present a detailed analysis of GW250114, the loudest gravitational-wave signal observed to date, using a waveform model capable of describing binary black holes in generic (ecce…
A parametrized model for gravitational waves from eccentric, precessing binary black holes: theory-agnostic tests of General Relativity with pTEOBResumS
Danilo Chiaramello, Nicolò Cibrario, Jacob Lange +4
Gravitational waves from binary black hole (BBH) mergers allow us to test general relativity in the strong-field, high-curvature regime. However, existing gravitational wave-based…
Revisiting GW150914 with a non-planar, eccentric waveform model
Rossella Gamba, Jacob Lange, Danilo Chiaramello +2
The first direct detection of gravitational waves by the LIGO collaboration, GW150914, marked the start of a new exciting era in astronomy, enabling the study of the Universe throu…
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…
