Zoo: quantifying morphological indicators of galaxy interaction'</a> </i><span style="font-size:14px">, the authors Casteels et al. used data from Galaxy Zoo 2 to search for morphological indicators of tidal interactions between pairs of galaxies, and identified
a number of morphological features that correlated with pair separation. Since then, newer surveys have provided higher resolution and more sensitive images of large numbers of galaxies, while machine learning has allowed for efficient labelling of larger
catalogues. In this talk, I will describe some of my work to reproduce and update the method given by Casteels et al. using more recent morphology data from Galaxy Zoo DESI.</span></div>
