Description
Motivated by the need to explain why galaxy spin is more strongly correlated to internal properties of galaxies such as star formation rate and stellar population age, rather than mass or environment, we look at how bar formation can change the observed galaxy spin measurement within one effective radius. Using a suite of galaxy simulations, we find when bar formation occurs and identify the associated heating of the disk. By making mock observables of these galaxy simulations using SimSpin, we find that bar formation causes a significant drop in the measured galaxy spin within one effective radius. Comparisons to observations from the SAMI galaxy survey are also made.
