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...
