SUMMARY:Hunting for Galactic PeVatrons with IceCube\, Preliminary Exam
 \, Leo Seen\, Physics PhD Graduate Student
DESCRIPTION:Detecting cosmic rays\, photons\, and neutrinos enables a 
 multi-messenger approach to studying high-energy processes in the Milk
 y Way. Recently\, IceCube reported neutrino emission from the Milky Wa
 y at 5.7𝜎\, hinting at potential contributions from individual sour
 ces. Theoretical sources within our Galaxy capable of accelerating cos
 mic rays up to peta-electronvolt (PeV) energies are known as Galactic 
 PeVatrons. When cosmic rays interact within or near their source\, the
 y produce 𝛾-rays and neutrinos. In this presentation\, I will motiv
 ate resolved 𝛾-ray sources as possible neutrino source candidates b
 y introducing ReGal-𝛾\, a neutrino source template generated by com
 bining 𝛾-ray source catalogs spanning GeV-PeV energies. Additionall
 y\, I will present results from a search for neutrino counterparts to 
 𝛾-ray sources with photon emission exceeding 100 TeV using 13 years
  of IceCube data. Finally\, I will discuss the prospects of differenti
 ating the Galactic neutrino source flux from the Galactic diffuse comp
 onent.
