DESCRIPTION:Abstract: Blazars are promising candidates for astrophysical ne
 utrino sources. Multi-messenger lepto-hadronic models based on proton--pho
 ton (p-gamma) interactions predict spectra that peak at high energies\, wh
 ereas statistical searches often assume a power-law shape\, emphasising lo
 wer energies. We investigate how these spectral assumptions impact neutrin
 o--blazar associations by incorporating physically motivated spectra into 
 our Bayesian point-source framework. Using predictions from Rodrigues et a
 l. (2024)\, we analyse 10 years of IceCube data and identify five candidat
 e sources. Our results show that $p\\gamma$ spectra suppress low-energy as
 sociations but may enhance high-energy ones. Strong associations then impl
 y that energetic neutrino events likely have much higher true energies tha
 n those inferred under a power-law assumption. This is particularly releva
 nt in light of the recent KM3NeT detection of the highest-energy neutrino\
 , reinforcing the need for theory-driven models to interpret multi-messeng
 er signals.\nVortragende(r): Julian Kuhlmann
