  • Two black holes
  • Black hole and neutron star
  • Two neutron stars
Each point is a merger (median source-frame masses; size by signal-to-noise ratio). Black holes found by gravitational waves are much heavier than those known from X-rays in our galaxy (under 20 M☉). The 3 M☉ boundary used here between neutron stars and black holes is conventional: the maximum mass of a neutron star is still uncertain (2 to 3 M☉).

The “final spiral” of GW250114_082203, the loudest signal

0.67 s before the merger, 20 Hzmerger, ≈ 61 Hz
Wave computed at Newtonian order from the published chirp mass (28.7 M☉ in the source frame, shifted by z = 0.09) for a pair of 33.8 and 32.3 M☉: frequency and amplitude rise together (the “chirp”) over about 19 cycles, up to the last stable orbit. It is not the measured signal (SNR 79), which also includes the merger and the ringing of the final black hole.

Show the data as a table
The detectors observe in runs (O1 in 2015–2016, O2 in 2016–2017, O3 in 2019–2020, O4 since May 2023) separated by breaks to improve their sensitivity: each gain in range multiplies the volume of universe probed, hence the number of mergers. 2021 and 2022 are empty: no run. The latest year is only partly published: catalogues come out more than a year after the detections.

Method and sources

Events of the cumulative GWTC catalogues (LIGO, Virgo, KAGRA) distributed by the GWOSC open data centre, keeping only confident detections (probability of astrophysical origin of at least 0.5) and each event once, in its most recent catalogue (GWTC-5.0, then 4.1, 4.0, 3, 2.1, 1). Parameters: medians and 90 % credible intervals of the published Bayesian analyses. UTC time derived from GPS time. The first detection, GW150914, was announced in February 2016 (Abbott et al., 2016).

Reading these data
Masses, distances and types are statistical estimates, sometimes broad (distance is often known to ± 30 %). Catalogues are revised: an event may change parameters, even status, from one version to the next. The detectors see heavy systems farther away: the distribution of observed masses is not that of the universe.
