Prospects for observing the microquasar SS 433 with the LACT array

We investigate the observational capabilities of the upcoming Large Array of imaging atmospheric Cherenkov Telescopes (LACT) for the microquasar SS 433 through detailed simulations. Our results indicate that a detection significance of 5σ can be achieved with approximately 30 h of observation. This exposure, coupled with LACT’s excellent angular resolution, enables the spatial separation of the eastern and western jets. Furthermore, based on the Large High Altitude Air Shower Observatory (LHAASO) spectral and morphological findings, the array is expected to distinguish the central hadronic component after roughly 100 h of observation. We also examine its ability to differentiate between the High Energy Stereoscopic System and LHAASO spectral models. These findings demonstrate LACT’s strong potential to eventually provide critical insights into particle acceleration in PeVatrons and the radiation mechanisms of microquasars.
