Description
To maximise the Trinity Observatory’s discovery potential for PeV-EeV tau neutrinos, identifying prime multi-messenger point sources is critical. X-ray bright and Compton-thick obscured AGN are compelling candidates; their dense environments drive efficient photohadronic neutrino production while attenuating gamma rays via pair production, making X-ray emission a vital diagnostic.
In this contribution, we explore Trinity’s sensitivity to transient ultra-high-energy tau neutrinos from diverse X-ray bright AGN. We outline a framework translating observed X-ray fluences into expected hadronic neutrino yields. By combining these spectra with Trinity's effective area, we forecast observable event rates. Accounting for source duty cycles and environmental opacity, we aim to identify optimal observational targets to help guide future multi-messenger pointing strategies.
