Overview of the source. Left: ALMA 2015.6 1.3 mm dust continuum from Brogan et al. (2016). The main regions MM1-4 are labelled in white. The peak positions of the bursting source, MM1B, as well as MM2 and MM4 are marked with crosses. The location of the millimetre cavity is marked in red. Right: JVLA 2015.9 5 cm continuum with 2017.8 22 GHz water masers overlaid in blue (Brogan et al. 2018). The positions and names of the water maser associations introduced in Section 1 are in green. The positions and orientations of the N-S and NW jets (solid and dashed-dotted respectively, from Brogan et al. 2018) and NW-SE jet (dashed line, from Chibueze et al. 2021) as well as the 0.5 pc NE-SW outflow (dotted line, from Qiu et al. 2011) are marked in red.
