5d Schwarzschild-Tangherlini spacetime: MST-like formalism for a Reduced Confluent Heun Equation
Donato Bini, Giorgio Di Russo, Veronica Fantini
We study the five-dimensional Schwarzschild-Tangherlini solution, with particular attention to its geodesic structure and massless scalar perturbations. In the probe limit, we pres…

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…

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…
