Title: STAR FORMATION TRIGGERED BY MICROQUASAR JETS

Abstract: We propose infrared imaging and spectroscopy of the star-forming region IRAS 19132+1035, where the star formation has apparently been induced by relativistic jets from the Galactic black hole binary GRS 1915+105. Using the VLA we recently found additional indications for the interaction between the jet source and IRAS source by the following time variations in the ionized gas of the star forming region: (1) the appearance of a new radio knot, and (2) blobs of radio emission that seem to be moving away from the microquasar at velocities of ~40,000 km/s, along directions close to the microquasar jet axis. To find unambiguous evidence of jet induced massive star formation, we wish to obtain infrared high resolution images and spectra of the IRAS source, to identify and characterize the massive star(s) and shocks induced by impinging jets. IRAS 19132+1035 is the first - and so far only - known case in the Milky Way of relativistic jets that may be triggering star formation. Because of its relative isolation and proximity compared to the much more distant extragalactic cases, study of this IRAS object is likely to yield results of high impact for our understanding of the physics in jet induced star formation, which is believed to have played an important role during early cosmic epochs, and in particular, during reionization, when the production of microquasars was prolific and the density of the Intergalactic Medium orders of magnitude larger than at present.
