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…
Black Hole Occupation Fraction: Dependence on Black Hole Mass Threshold, Environment, Resolution and Redshift
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…
Stellar halos of bright central galaxies II: Scaling relations, colors and metallicity evolution with redshift
Emanuele Contini, Marilena Spavone, Rossella Ragusa +2
We study the formation and evolution of stellar halos (SHs) around bright central galaxies (BCGs), focusing on their scaling relations, colors, and metallicities across cosmic time…
On the Origin of Intracluster Light based on the High-resolution Simulation, NewCluster
Seyoung Jeon, Emanuele Contini, San Han +11
Intracluster light (ICL) is a key component of galaxy clusters, with the potential to trace their dynamical assembly histories and the underlying dark matter distribution. Despite…
On the Origin of Gas-stripping of Galaxies in Group Environments
Jinsu Rhee, Christophe Pichon, Yohan Dubois +12
We investigate how low-mass group environments () influence the gas content of their satellite galaxies with using…
Roles of Supernova and Active Galactic Nucleus Feedback in Shaping the Baryonic Content in a Wide Range of Dark Matter Halo Masses
Emanuele Contini, Changjo Seo, Jinsu Rhee +2
We build upon FEGA25 (Contini et al 2025), a previously introduced semi-analytic model for galaxy formation and evolution, focusing on its enhanced treatment of supernova and activ…
