We present high-resolution (synthesised beam size 0."088x0."083 or 25x23pc$^2$) Atacama Large Millimetre/submillimetre Array (ALMA) $^{12}$CO(2-1) lineand 236 GHz continuum observations, as well as 5 GHz enhanced Multi-ElementRadio Linked Interferometer Network (e-MERLIN) continuum observations, of NGC0708; the brightest galaxy in the low-mass galaxy cluster Abell 262. The lineobservations reveal a turbulent, rotating disc of molecular gas in the core ofthe galaxy, and a high-velocity, blue-shifted feature ~0."4 (~113 pc) from itscentre. The sub-millimetre continuum emission peaks at the nucleus, but extendstowards this anomalous CO emission feature. No corresponding elongation isfound on the same spatial scales at 5 GHz with e-MERLIN. We discuss potentialcauses for the anomalous blue-shifted emission detected in this source, andconclude that it is most likely to be a low-mass in-falling filament ofmaterial condensing from the hot intra-cluster medium via chaotic coldaccretion, but it is also possible that it is a jet-driven molecular outflow.We estimate the physical properties this structure has in these two scenarios,and show that either explanation is viable. We suggest future observations withintegral field spectrographs will be able to determine the true cause of thisanomalous emission, and provide further evidence for interaction betweenquenched cooling flows and mechanical feedback on both small and large scalesin this source.
