Multimessenger Emission from Very-High-Energy Black Hole-Jet Systems in the Milky Way

Abstract

Microquasars, compact binary systems with an accreting stellar-mass black hole or neutron star, are promising candidates for high-energy particle acceleration. Recently, the LHAASO collaboration reported on the detection of $>100$ TeV $\gamma$-ray emission from five microquasars, suggesting that these sources are efficient particle accelerators. In microquasars, high-energy $\gamma$-rays can be produced in large-scale jets or winds. In this work, we explore the X-ray, $\gamma$-ray and neutrino emission from SS 433, V4641 Sgr and GRS 1905+105. We consider leptonic and hadronic scenarios to explain the spectra observed by LHAASO and other high-energy $\gamma$-ray detectors. We estimate the neutrino flux associated with the hadronic component and investigate the detectability of neutrinos from these sources in current and future neutrino telescopes. We find that among the three sources, V4641 Sgr has the best prospects of observation with a combined next-generation neutrino telescopes.
