Third post-Newtonian effective-one-body Hamiltonian in scalar-tensor and Einstein-scalar-Gauss-Bonnet gravity
Félix-Louis Julié, Vishal Baibhav, Emanuele Berti +1
We build an effective-one-body (EOB) Hamiltonian at third post-Newtonian (3PN) order in scalar-tensor (ST) and Einstein-scalar-Gauss-Bonnet (ESGB) theories of gravity. The latter i…
Dropping Anchor: Understanding the Populations of Binary Black Holes with Random and Aligned Spin Orientations
Vishal Baibhav, Zoheyr Doctor, Vicky Kalogera
The relative spin orientations of black holes (BHs) in binaries encode their evolutionary history: BHs assembled dynamically should have isotropically distributed spins, while spin…
Dynamical formation of black hole binaries in dense star clusters: Rapid cluster evolution code
Konstantinos Kritos, Vladimir Strokov, Vishal Baibhav +1
Gravitational-wave observations have just started probing the properties of black hole binary merger populations. The observation of binaries with very massive black holes and sign…
Nonlinear effects in black hole ringdown
Mark Ho-Yeuk Cheung, Vishal Baibhav, Emanuele Berti +8
We report evidence for nonlinear modes in the ringdown stage of the gravitational waveform produced by the merger of two comparable-mass black holes. We consider both the coalescen…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
The impact of relativistic corrections on the detectability of dark-matter spikes with gravitational waves
Nicholas Speeney, Andrea Antonelli, Vishal Baibhav +1
Black holes located within a dark matter cloud can create overdensity regions known as dark matter spikes. The presence of spikes modifies the gravitational-wave signals from binar…
