Reply to Comment on "Analysis of Ringdown Overtones in GW150914"
Gregorio Carullo, Roberto Cotesta, Emanuele Berti +1
In this Reply we include the corrections suggested in the Comment [Phys. Rev. Lett. 131, 169001]. We show that their impact on our results is small, and that the overall conclusion…
Extracting linear and nonlinear quasinormal modes from black hole merger simulations
Mark Ho-Yeuk Cheung, Emanuele Berti, Vishal Baibhav +1
In general relativity, when two black holes merge they produce a rotating (Kerr) black hole remnant. According to perturbation theory, the remnant emits "ringdown" radiation: a sup…
A Joint Fermi-GBM and Swift-BAT Analysis of Gravitational-Wave Candidates from the Third Gravitational-wave Observing Run
C. Fletcher, J. Wood, R. Hamburg +1696
We present Fermi Gamma-ray Burst Monitor (Fermi-GBM) and Swift Burst Alert Telescope (Swift-BAT) searches for gamma-ray/X-ray counterparts to gravitational wave (GW) candidate even…
Formulation Improvements for Critical Collapse Simulations
Daniela Cors, Sarah Renkhoff, Hannes R. Rüter +2
The precise tuning required to observe critical phenomena in gravitational collapse poses a challenge for most numerical codes. First, threshold estimation searches may be obstruct…
Black-hole mergers in disklike environments could explain the observed - correlation
Alessandro Santini, Davide Gerosa, Roberto Cotesta +1
Current gravitational-wave data from stellar-mass black-hole binary mergers suggest a correlation between the binary mass ratio and the effective spin : more un…
Probing wave-optics effects and low-mass dark matter halos with lensing of gravitational waves from massive black holes
Mesut Çalışkan, Neha Anil Kumar, Lingyuan Ji +4
The Laser Interferometer Space Antenna (LISA) will detect gravitational waves (GWs) emitted by massive black hole binaries (MBHBs) in the low-frequency (mHz) band. Low-mass l…
Single-event likelihood of star cluster properties with LIGO-Virgo-Kagra binary black hole observations
Ken K. Y. Ng, Konstantinos Kritos, Andrea Antonelli +2
The population of binary black hole mergers observed in gravitational waves, together with astrophysical simulations, can help us to understand the properties of the progenitors an…
Classifying the generation and formation channels of individual LIGO-Virgo-KAGRA observations from dynamically formed binaries
Andrea Antonelli, Konstantinos Kritos, Ken K. Y. Ng +2
We address two important questions in gravitational-wave astronomy. What is the astrophysical formation scenario leading to black-hole binary mergers? Did some of the merging black…
Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1692
Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about funda…
Laying the foundation of the effective-one-body waveform models SEOBNRv5: improved accuracy and efficiency for spinning non-precessing binary black holes
Lorenzo Pompili, Alessandra Buonanno, Héctor Estellés +21
We present SEOBNRv5HM, a more accurate and faster inspiral-merger-ringdown gravitational waveform model for quasi-circular, spinning, nonprecessing binary black holes within the ef…
Agnostic black hole spectroscopy: Quasinormal mode content of numerical relativity waveforms and limits of validity of linear perturbation theory
Vishal Baibhav, Mark Ho-Yeuk Cheung, Emanuele Berti +5
Black hole spectroscopy is the program to measure the complex gravitational-wave frequencies of merger remnants, and to quantify their agreement with the characteristic frequencies…
