LIGO/Virgo G299232: COINCIDENT IceCube neutrino observation UPDATE
Abstract
In GCN 21694 we reported the identification of an IceCube neutrino candidate that is temporally (within [-500s,500s]) and directionally (within 90% CL) coincident with LIGO/Virgo G298048. We reran our analysis using the updated three-detector skymap, bayestar-HLV.fits.gz. The same neutrino candidate is still COINCIDENT with the updated map. The properties of the neutrino candidate are below: # dt[s] RA[deg] Dec[deg] E[TeV] Sigma[deg] ------------------------------------------------------------------ 1. -233.82 28.2 44.8 0.39 3.8 (dt--time from GW in [seconds]; RA/Dec--sky location in [degrees]; E--reconstructed secondary muon energy in [TeV]; Sigma--uncertainty of direction reconstruction in [degrees]) A coincident neutrino-GW skymap has been posted to GraceDB (<https://gracedb.ligo.org/apiweb/events/G299232/files/coinc_skymap_initial_icecube.png,1>). A JSON-formatted list of the neutrinos used can be downloaded from GraceDB at: <https://gracedb.ligo.org/apiweb/events/G299232/files/IceCubeNeutrinoList.json,1>
