Identifying Jet-ISM Interaction Zones near the Microquasars GRS 1758-258 and 1E 1740.7-2942
Abstract
Relativistic jets launched from accreting black holes carry large amounts of energy and matter into their surrounding environment. Identifying and probing the physical conditions of the gas and dust in regions where these jets interact with the ISM, can provide valuable information on unknown jet properties, most notably, the total jet power, composition, duty cycles, and the efficiency of jet feedback. Black hole X-ray binaries (BHXBs) are ideal targets for studying such interactions in detail, due to their close proximity and the rapid timescale evolution of BHXB jet activity. In this talk, I will present new ALMA observations of candidate jet-ISM interaction zones near the BHXBs GRS 1758-258 and 1E 1740.7-2942, combined with VLA, WISE and Spitzer data. With this suite of multi-wavelength data, we identify structures that likely trace jet-driven cavities in the gas surrounding these systems, and estimate the time averaged jet power from both systems by using these newly discovered structures as calorimeters. This work highlights how astrochemistry can be used to both identify jet-ISM interaction zones and probe jet feedback from Galactic X-ray binaries.
