Isophote Shapes of Early-Type Galaxies in Massive Clusters at $z\sim 1$ and 0

Kazuma Mitsuda, Mamoru Doi, Tomoki Morokuma +5

We compare the isophote shape parameter $a_4$ of early-type galaxies (ETGs) between $z\sim 1$ and 0 as a proxy for dynamics to investigate the epoch at which the dynamical propert…
