New catalog more than doubles the number of gravitational-wave detections made by LIGO, Virgo, and KAGRA observatories

The latest crop of space-time wobbles includes a variety of heavy, fast-spinning, and lopsided colliding black holes.

O4a, der erste Teil des 4. gemeinsamen Beobachtungslaufs der Gravitationswellen-Detektoren, neigt sich seinem Ende zu. Schauen wir daher mal auf die vorläufigen Ergebnisse (Signalkandidaten):

⏱️ Dauer des Laufs: 231 Tage
🔢 81 signifikante Signalkandidaten
🚨 Ein neuer Kandidat alle 2,9 Tage
➡️ https://gracedb.ligo.org/superevents/public/O4/
ℹ️ https://www.aei.mpg.de/425374/current-gravitational-wave-astronomy

O4a wird am 16. Januar 2024 um 16:00 UTC enden, gefolgt von einer ca. 8-wöchigen Wartungspause.

As O4a, the first part of the fourth joint observing run of the gravitational-wave detector network, draws to a close, let's take a look at the preliminary results (signal candidates):

⏱️ Run duration: 231 days
🔢 81 significant signal candidates
🚨 A new candidate every 2.9 days
➡️ https://gracedb.ligo.org/superevents/public/O4/
ℹ️ https://www.aei.mpg.de/26370/current-gravitational-wave-astronomy

O4a will end at 16:00 UTC on 16 January 2024 followed by an ~8 week maintenance break.

Tuesday morning at #JSM2023 and we have two talks about continuous #GravitatiionalWaves. Unfortunately they're in simultaneous sessions. So you have your pick between me talking in the topic contributed session "Pulling Signal out of Noise for Data-Driven Discoveries in Astronomy" or Alan Knee in the invited session "The True North Strong and ... Amazing at Astrostatistics!" #LIGO #Virgo #KAGRA #ContinuousWaves #astrostatistics #NeutronStars #JSM

Attending my first in person #JSM this week. It'll be speaking about searches for continuous gravitational waves Tuesday morning in the topic contributed session on "Pulling Signal out of Noise for Data-Driven Discoveries in Astronomy". #JSM2023 #GravitationalWaves #LIGO #Virgo #KAGRA

Gravitational-wave sleuths look for more cosmic crashes
After three years of upgrading and waiting, due in part to the coronavirus pandemic, the Laser Interferometer Gravitational-wave Observatory has officially resumed its hunt for the signatures of crashing black holes and neutron stars.
