SUMMARY:Multimessenger Probes of High-Energy Neutrino Production in AG
 N and Microquasars\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Jose 
 Carpio\, University of Nevada
DESCRIPTION:The discovery of astrophysical neutrinos by the IceCube Ne
 utrino Observatory established neutrinos as a new messenger\, opening 
 a window to the most extreme particle accelerators in the Universe. Cr
 eated in hadronic interactions\, high-energy neutrinos are necessarily
  co-produced with γ-rays. The detection of neutrinos from NGC 1068\, 
 without accompanying γ-rays\, thus reveals production in γ-ray–opa
 que environments\, pointing to dense AGN cores as powerful accelerator
 s. Meanwhile\, IceCube's observation of Galactic neutrinos has opened 
 a new front in understanding the sources of cosmic rays. Recent HAWC a
 nd LHAASO detections of >100 TeV γ-rays from microquasars such as SS 
 433 and V4641 Sgr show that compact binaries can also accelerate parti
 cles to high energies. This observation motivates targeted neutrino se
 arches to determine whether the γ-rays are leptonic or hadronic in na
 ture. In this talk\, I will use the measured AGN neutrino spectra and 
 γ-ray data to constrain source models and their contribution to the i
 sotropic neutrino flux. In addition\, I will use the γ-ray and X-ray 
 data from SS 433 and V4641 Sgr to predict their neutrino fluxes from a
  hadronic component and assess their detection prospects with current 
 and next-generation neutrino detectors.
