The Illusion of Morphology in Tidal Structures: Changes to Stellar Shells and Streams in Non-Spherical Haloes
Smrithi Gireesh Babu, Viraj Ekanayaka, William H. Oliver +1
We identify shell-like tidal structures in flattened haloes that appear stream-like under different projections. This projection dependence demonstrates how changes in the host hal…

Streams and Shells Decoded: A Density-Driven Approach to Stellar Clustering in Galactic Halos with AstroLink
Viraj Ekanayaka, Smrithi Gireesh Babu, William H. Oliver +1
We present a novel method to differentiate stream-like and shell-like tidal remnants of stellar systems in galactic halos using the density-based approach of the clustering algorit…
