    Hidden molecular outflow in the LIRG Zw 049.057
    (2018) Falstad, N.; Aalto, S.; Mangum, J. G.; Costagliola, F.; Gallagher, J. S.; Gonzalez-Alfonso, E.; Sakamoto, K.; Konig, S.; Muller, S.; Evans, A. S.; Privon, G. C.
    Context. Feedback in the form of mass outflows driven by star formation or active galactic nuclei is a key component of galaxy evolution. The luminous infrared galaxy Zw 049.057 harbours a compact obscured nucleus with a possible far-infrared signature of outflowing molecular gas. Due to the high optical depths at far-infrared wavelengths, however, the interpretation of the outflow signature is uncertain. At millimeter and radio wavelengths, the radiation is better able to penetrate the large columns of gas and dust responsible for the obscuration.
