EXAMINING THE INFLUENCE OF GALAXY INTERACTIONS ON THEIR NON-THERMAL RADIO EMISSION
A strong correlation has been known to exist between the far-infrared (FIR) and radio emission of the star-forming galaxies. Observations have shown that although scatter is present, this correlation holds over a range of redshifts and does not evolve. However, there has been a number of more recent observations, especially in higher redshift surveys, indicating the opposite. The question that then presents itself is - what is driving this evolution? In this work we explore the possibility that the answer might be hiding in galactic interactions and revealed by morphology. We analyze a COSMOS sample of submillimeter galaxies, whose morphologies have been previously determined. In this sample we look at the FIR-radio correlation separately in galaxies of different morphological types. We find that, while for both disk and irregular star-forming galaxies there are hints of evolution of this correlation with redshift, where this evolution appears to be stronger in irregular galaxies, due to low number statistics, both samples are also consistent with no evolution, making it at this point, difficult to discriminate between models.
