Galactic microquasar jets may eject electron-proton plasma, producing detectable high-energy neutrinos before radio flares. This discovery offers a new way to study microquasar jet physics.

Area of Science:

  • Astrophysics
  • Particle Physics
  • High-Energy Astronomy

Background:

  • Galactic microquasars are transient astronomical sources powered by accreting stellar-mass black holes or neutron stars.
  • These systems are known to launch powerful relativistic jets.

Purpose of the Study:

  • To investigate the potential observational signatures of electron-proton dominated jets in microquasars.
  • To establish a connection between neutrino production and jet ejection events.

Main Methods:

  • Theoretical modeling of photomeson interactions within microquasar jets.
  • Simulation of neutrino and radio flare emission from transient sources.

Main Results:

  • Predicts a several-hour outburst of 1-100 TeV neutrinos preceding radio flares from major ejection events.

  • Suggests that several neutrinos could be detected from a single outburst by a 1 km(2) detector.

    • Conclusions:

    • Neutrino emission from photomeson interactions serves as a crucial precursor to radio flares in microquasar jets.
    • Neutrino detection provides a powerful new tool for probing the physics of microquasar jet formation and evolution.
