On the Separation Between the Brightest Cluster Galaxy and the Intracluster Light
Emanuele Contini, Sukyoung K. Yi
We present a model-based framework to define an aperture separation between the brightest cluster galaxy (BCG) and the intracluster light (ICL). Using the intrinsic BCG and ICL com…

Emanuele Contini, J. K. Jang, Jinsu Rhee +2
We take advantage of the state-of-the-art semi-analytic model \texttt{FEGA25} \citep{contini2025}, run on merger trees extracted from three dark matter-only cosmological simulation…
Effects of resolution and local stability on galactic disks: Halo resolution and softening on bar formation
SungWon Kwak, Ivan Minchev, Matthias Steinmetz +1
Using N-body simulations, we examine the impact of dark matter (DM) halo resolution and gravitational softening on bar formation. We generate isolated disk-halo systems with fixed…
Effects of Resolution and Local Stability on Galactic Disks: I. Multiple Spiral Mode Formation via Swing Amplification
