Tracing the dynamical states and mass accretion histories of galaxy clusters in IllustrisTNG
Rashaad Reid, Syeda Lammim Ahad, Roan Haggar +2
As the largest and most recently formed stage of hierarchical structure, present-day galaxy clusters are predicted to have a broad range of late-time assembly histories. This diver…
Cluster properties as a function of dynamical state in the DESI Legacy x UNIONS surveys
Syeda Lammim Ahad, Rashaad Reid, Charlie T. Mpetha +10
We investigate how the dynamical state of galaxy clusters influences their galaxy populations and mass distributions. Using photometrically selected clusters from the DESI Legacy I…
The intragroup light in KiDS+GAMA groups: A stacking analysis
S. L. Ahad, H. Hoekstra, Y. M. Bahé +4
Galaxy groups and clusters assembled through dynamical interactions of smaller systems, resulting in the formation of a diffuse stellar halo known as the intragroup or intracluster…
Insights into environmental quenching at : an enhancement of faint, low-mass passive galaxies in clusters
Harry Gully, Nina Hatch, Syeda Lammim Ahad +11
Understanding the processes that transform star-forming galaxies into quiescent ones is key to unraveling the role of environment in galaxy evolution. We present measurements of th…
Intra-Cluster Light as a Dynamical Clock for Galaxy Clusters: Insights from the MAGNETICUM, IllustrisTNG, Hydrangea and Horizon-AGN Simulations
Lucas C. Kimmig, Sarah Brough, Klaus Dolag +19
As the most massive nodes of the cosmic web, galaxy clusters represent the best probes of structure formation. Over time, they grow by accreting and disrupting satellite galaxies,…
Euclid preparation LXX. Forecasting detection limits for intracluster light in the Euclid Wide Survey
Euclid Collaboration, C. Bellhouse, J. B. Golden-Marx +292
The intracluster light (ICL) permeating galaxy clusters is a tracer of the cluster's assembly history, and potentially a tracer of their dark matter structure. In this work we expl…
