Intracluster light and dark matter halo shapes reflect common assembly, not mutual coupling: shape correspondence in CDM but not SIDM
G. Martin, N. A. Hatch, W. Cui +8
The intracluster light (ICL) has been proposed as a luminous tracer of the dark matter (DM) halo shape in galaxy clusters, with recent observational studies and CDM simulations…
Enabling Cosmic Web Analysis at Gigaparsec Scales: A Multi Block Approach for DisPerSE
Ankit Singh, Frazer Pearce, Meghan Gray +1
The paper introduces a frozen‑core, multi‑block technique that enables the DisPerSE filament finder to process gigaparsec‑scale cosmological simulations by preserving global topolo…
A Consistent Comparison of Intracluster Light Assembly in Simulations I. Redshift Evolution and Progenitor Galaxies
Harley J. Brown, Garreth Martin, Frazer R. Pearce +5
The tidal stripping of satellite galaxies and the stellar detritus ejected during galaxy mergers builds up a diffuse stellar component in galaxy clusters known as the intracluster…
Identifying group galaxies merging with massive clusters using machine learning
Rhys Jordan, Meghan E. Gray, Alfonso Aragón-Salamanca +3
The environment plays a critical role in galaxy evolution, with galaxy clusters and their infall regions offering diverse conditions that shape galaxies before they enter the dense…
Intracluster light as a dark matter tracer: how their spatial and kinematic relationship is shaped by satellite demographics
G Martin, F R Pearce, N A Hatch +6
We investigate how the orbital evolution and mass distribution of infalling satellite galaxies shape the phase-space and radial distributions of intracluster light (ICL) relative t…
The role of mergers and rejuvenation in the buildup of the quiescent population at cosmic noon
Jimi Evan Harrold, Omar Almaini, Frazer R. Pearce +6
We investigate the quenching of galaxies using a mock observational lightcone generated from the Semi-Analytic Model (SAM) L-Galaxies, closely matched to observations from the UKID…
