Molecular Clouds Poessibly Associated with the Jets from a Compact Star of L=348.5 degress and SS433; Galactic vapor trail as a probe of black hole candidates
We have discovered a group of linearly aligned four molecular clouds over about 400 pc nearly perpendicular to the galactic plane at a distance of 6 kpc toward ~ 348.5°in galactic longitude and that of molecular clouds on a straight line nearly coincident with the X-ray jet axis on the both side up to 150 pc, three times larger than previously known by X-my, from SS433 from the NANTEN <12>CO dataset. We argue that they represent molecular clouds which might be created by the interaction between the jet and the interstellar medium. We present a scenario that the interaction between the jet and interstellar medium induced the formation of molecular clouds and/or enhanced the molecular emission _> 10<5> yrs ago. This scenario explains the molecular jet quantitatively if we assume the same physical parameters with those derived for the SS433 jet, the most-developed jet from compact object in the Milky Way known to date. The finding might offer a new tool, galactic vapor trail, to search for relativistic jet driven by a black hole or a neutron star over more than 10 times longer timescale than the direct detection of high energy radiation.
