Gamma-Ray Bursts (GRBs) are now considered as relativistic jets. We analyze the gravitational waves from the acceleration stage of the GRB jets. We show that (i) the point mass approximation is not appropriate if the opening half-angle of the jet is larger than the inverse of the Lorentz factor of the jet, (ii) the gravitational waveform has many step function like jumps, and (iii) the practical DECIGO and BBO may detect such an event if the GRBs occur in Local group of galaxy. We found that the light curve of GRBs and the gravitational waveform are anti-correlated so that the detection of the gravitational wave is indispensable to determine the structure of GRB jets.

  1. A "Neutrino Fog" For Gravitational Waves: The Stochastic Gravitational Wave Background from Supernova Neutrino Memory

    astro-ph.HE 2026-08 conditional novelty 6.0 of 10

    Using 3D supernova simulations, the authors predict that neutrino memory creates a gravitational wave background with Omega_GW around 1e-16 at 0.1 Hz, within reach of future space-based detectors.

  2. Toward claiming a detection of gravitational memory

    gr-qc 2026-01 unverdicted novelty 6.0 of 10

    A framework using scale separation in the Isaacson description defines observable gravitational memory rise for compact binary coalescences, providing a basis for hypothesis testing in LISA data.

  3. Finding Supermassive Black Hole Binary Mergers in Pulsar Timing Array Data

    astro-ph.HE 2025-10 conditional novelty 6.0 of 10

    A complete SMBHB waveform model enables unified PTA searches for mergers and memory signals, with parameter recovery shown on simulated data for 10^8-10^10 solar mass systems.
