Evidence of Absence of Tidal Features in the Outskirts of Ultra Diffuse Galaxies in the Coma Cluster

Understand

We study the presence of tidal features associated with ultra diffuse galaxies (UDGs) in galaxy clusters.

• Specifically, we stack deep Subaru images of UDGs in the Coma cluster to determine whether they show position angle twists at large radii.
• Selecting galaxies with central surface brightness (g-band) >24 magarcsec^{-2} and projected half-light radius >1.5 kpc, we identify 287 UDGs in the Yagi et al.
• 2016 catalog of low surface brightness Coma objects.
