SUMMARY:Searches for High-energy Neutrinos Accompanying Astrophysical 
 Transients\, Preliminary Exam\, Alicia Mand
DESCRIPTION:Multi-messenger astronomy enables us to probe extreme astr
 ophysical phenomena in new ways. In particular\, astrophysical neutrin
 os reveal information that is not available via any other messenger. N
 eutrinos are the “smoking gun” signature for hadronic processes �
 � meaning that identification of neutrino sources can elucidate the or
 igins of high-energy cosmic rays. Multiple observatories\, such as the
  IceCube Neutrino Observatory and KM3NeT\, are currently collecting da
 ta on astrophysical neutrinos. The first detection of high-energy astr
 ophysical neutrinos was reported in 2013 by the IceCube collaboration.
  However\, despite detecting astrophysical neutrinos for over a decade
 \, the sources of these neutrinos are still largely unknown\, despite 
 thorough searches. I will present results and work in progress from th
 ree such searches using data from the IceCube Neutrino Observatory. Th
 e first is a search for neutrinos from SN 2023ixf\, the closest and br
 ightest core-collapse supernova in the last decade. The second is a fo
 llow-up of the highest-energy neutrino ever detected\, measured by KM3
 NeT to have energy approximately 200 PeV\, to search for additional ne
 utrinos from the same direction that could help determine its origin. 
 Finally\, I will present a search under development for neutrinos in t
 he directions of fast radio bursts (FRBs) detected by the CHIME telesc
 ope.
