DESCRIPTION:Speakers: Andrew Cheek\n\nNeutrino telescopes offer a powerful
  channel for indirect dark matter (DM) detection. The recent ultra-high-en
 ergy neutrino event KM3-230213A\, detected by KM3NeT at approximately 220 
 PeV\, has been proposed as a possible signature of decaying super-heavy da
 rk matter. At first glance this interpretation appears disfavored\, as the
  event's arrival direction points away from the Galactic Centre.I present 
 a statistical method for quantifying the likelihood that this event origin
 ates from DM decay\, and for determining how many additional events would 
 be required to confirm or rule out this hypothesis. I then discuss a recen
 t sensitivity study for Galactic Centre DM annihilations with the planned 
 TRIDENT neutrino telescope. We find that TRIDENT can reach the thermal rel
 ic cross-section benchmark for DM masses between 1–100 TeV\, and we cont
 extualize this result within the broader DM landscape by studying a specif
 ic dark matter model. Furthermore\, our analysis is the first of its kind 
 to account for the stochastic nature of the Galactic plane neutrino backgr
 ound\, whose measurement will itself be an important astrophysical result.
  I conclude with a brief discussion of ongoing work and future directions.
