Using IllustrisTNG circularity catalogs, the authors show that a disk fraction threshold of Fdisk=0.25 separates early- and late-type galaxies well enough to recover the morphology-density relation at z=0.

Galaxy Morphology Classification: Are Stellar Circularities Enough?
Using IllustrisTNG circularity catalogs, the authors show that a disk fraction threshold of Fdisk=0.25 separates early- and late-type galaxies well enough to recover the morphology-density relation at z=0.
