    Atomic hydrogen bridge fueling NGC 4418 with gas from VV 655
    (2017) Varenius, E.; Costagliola, F.; Kloeckner, H. -R.; Aalto, S.; Spoon, H.; Marti-Vidal, I.; Conway, J. E.; Privon, G. C.; Konig, S.
    Context. The galaxy NGC4418 harbours a compact (< 20 pc) core with a very high bolometric luminosity (similar to 10(11) L-circle dot). As most of the galaxy energy output comes from this small region, it is of interest to determine what fuels this intense activity. An interaction with the nearby blue irregular galaxy VV655 has been proposed, where gas acquired by NGC4418 could trigger intense star formation and / or black hole accretion in the centre.

    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.
