Uncovering subdominant multipole asymmetries in binary black-hole mergers
Jannik Mielke, Angela Borchers, Frank Ohme
In dynamically formed binaries, the spins of the black holes tend to be misaligned with the system's orbital angular momentum. This causes the spins to precess and leads to an asym…
Is GW231123 a hierarchical merger?
Lachlan Passenger, Sharan Banagiri, Eric Thrane +4
The binary black hole merger GW231123 is both the most massive gravitational-wave event observed and has the highest component spins measured to date. The dimensionless spins of th…
Gravitational-wave kicks impact spins of black holes from hierarchical mergers
Angela Borchers, Claire S. Ye, Maya Fishbach
One proposed black hole formation channel involves hierarchical mergers, where black holes form through repeated binary mergers. Previous studies have shown that such black holes f…
Revisiting the relationship of black-hole kicks and multipole asymmetries
Jannik Mielke, Shrobana Ghosh, Angela Borchers +1
Precession in black-hole binaries is caused by a misalignment between the total spin and the orbital angular momentum. The gravitational-wave emission of such systems is anisotropi…
Observability of spin precession in the presence of a black-hole remnant kick
Angela Borchers, Frank Ohme, Jannik Mielke +1
Remnants of binary black-hole mergers can gain significant recoil or kick velocities when the binaries are asymmetric. The kick is the consequence of anisotropic emission of gravit…
Inconsistent black hole kick estimates from gravitational-wave models
Angela Borchers, Frank Ohme
The accuracy of gravitational-wave models of compact binaries has traditionally been addressed by the mismatch between the model and numerical-relativity simulations. This is a mea…
Black-hole kicks: a tool to measure the accuracy of gravitational-wave models
Angela Borchers, Frank Ohme
Asymmetric binary systems radiate linear momentum through gravitational waves, leading to the recoil of the merger remnant. Black-hole kicks have attracted much attention because o…
Time domain phenomenological model of gravitational wave subdominant harmonics for quasi-circular non-precessing binary black hole coalescences
Héctor Estellés, Sascha Husa, Marta Colleoni +5
In this work we present an extension of the time domain phenomenological model IMRPhenomT for gravitational wave signals from binary black hole coalescences to include subdominant…
Accelerating the evaluation of inspiral-merger-ringdown waveforms with adapted grids
Cecilio García-Quirós, Sascha Husa, Maite Mateu-Lucena +1
This paper presents an algorithm to accelerate the evaluation of inspiral-merger-ringdown waveform models for gravitational wave data analysis. While the idea can also be applied i…
