Late-time tails in nonlinear evolutions of merging black holes
Marina De Amicis, Hannes Rüter, Gregorio Carullo +17
We uncover late-time gravitational-wave tails in fully nonlinear 3+1 dimensional numerical relativity simulations of merging black holes, using the highly accurate SpEC code. We ac…
Real modes and null memory contributions in effective-one-body models
Simone Albanesi
We introduce a novel approach to describe real-valued modes from inspiral to merger and ringdown in effective-one-body models, including both oscillatory and null memory cont…
Direct current memory effects in effective-one-body waveform models
Elisa Grilli, Andrea Placidi, Simone Albanesi +2
The direct current (DC) memory is a non-oscillatory, hereditary component of the gravitational wave (GW) signal that represents one of the most peculiar manifestations of the nonli…
Search for gravitational waves emitted from SN 2023ixf
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1780
We present the results of a search for gravitational-wave transients associated with core-collapse supernova SN 2023ixf, which was observed in the galaxy Messier 101 via optical em…
A search using GEO600 for gravitational waves coincident with fast radio bursts from SGR 1935+2154
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1780
The magnetar SGR 1935+2154 is the only known Galactic source of fast radio bursts (FRBs). FRBs from SGR 1935+2154 were first detected by CHIME/FRB and STARE2 in 2020 April, after t…
Swift-BAT GUANO follow-up of gravitational-wave triggers in the third LIGO-Virgo-KAGRA observing run
Gayathri Raman, Samuele Ronchini, James Delaunay +1819
We present results from a search for X-ray/gamma-ray counterparts of gravitational-wave (GW) candidates from the third observing run (O3) of the LIGO-Virgo-KAGRA (LVK) network usin…
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…
Inspiral-inherited ringdown tails
Marina De Amicis, Simone Albanesi, Gregorio Carullo
We study the late-time relaxation of a perturbed Schwarzschild black hole, driven by a source term representing an infalling particle in generic orbits. We consider quasi-circular…
Scattering and dynamical capture of two black holes: synergies between numerical and analytical methods
Simone Albanesi, Alireza Rashti, Francesco Zappa +6
We study initially unbound systems of two black holes using numerical relativity (NR) simulations performed with GR-Athena++. We focus on regions of the parameter space close to th…
Observation of Gravitational Waves from the Coalescence of a Compact Object and a Neutron Star
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1793
We report the observation of a coalescing compact binary with component masses and (all measurements quoted at the 90% credible le…
Ultralight vector dark matter search using data from the KAGRA O3GK run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1800
Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating l…
