Starburst-AGN mixing: TYPHOON observations of NGC 1365, NGC 1068, and
  the effect of spatial resolution on the AGN fraction
  We demonstrate a robust method of resolving the star-formation and AGN
contributions to emission lines using two very well known AGN systems: NGC
1365, and NGC 1068, using the high spatial resolution data from the
TYPHOON/PrISM survey. We expand the previous method of calculating the AGN
fraction by using theoretical-based model grids rather than empirical points.
The high spatial resolution of the TYPHOON/PrISM observations show evidence of
both star formation and AGN activity occurring in the nuclei of the two
galaxies. We rebin the data to the lower resolutions, typically found in other
integral field spectroscopy surveys such as SAMI, MaNGA, and CALIFA. The
results show that when rebinned from the native resolution of TYPHOON (< 200
pc/pixel) to 1 kpc/pixel, the effects include a roughly 3 kpc increase in the
radius of measured AGN activity, and a factor of 2 to 7 increase in the
detection of low surface brightness features such as shocks. All of this
information is critical, because information on certain physical processes may
be lost at varying resolutions. We make recommendations for analysing data at
current IFU survey resolutions.
