A new period of activity in the core of NGC660
  The core of the nearby galaxy NGC660 has recently undergone a spectacular
radio outburst; using a combination of archival radio and Chandra X-ray data,
together with new observations, the nature of this event is investigated. Radio
observations made using e-MERLIN in mid-2013 show a new compact and extremely
bright continuum source at the centre of the galaxy. High angular resolution
observations carried out with the European VLBI Network show an obvious
jet-like feature to the north east and evidence of a weak extension to the
west, possibly a counter-jet. We also examine high angular resolution HI
spectra of these new sources, and the radio spectral energy distribution using
the new wide-band capabilities of e-MERLIN. We compare the properties of the
new object with possible explanations, concluding that we are seeing a period
of new AGN activity in the core of this polar ring galaxy.
