  • We study the stellar morphological evolution of disk galaxies within clusters in the TNG50 and TNG100 runs from the IllustrisTNG simulation suite. We select satellites of masses $10^{9.7}<=M_{*,z=0}/M_{sun}<=10^{11.6}$ residing in clusters of total masses $10^{14}<=M_{\text{200c,z=0}}/M_{sun}<10^{14.6}$ at z=0 and study those that were disks at accretion according to a kinematic morphology indicator (the circularity fraction). The galaxies' histories are traced from the time of accretion to $z… CONTINUE READING
