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…

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…

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…

Intracluster light is a close tracer of the dark matter halo shape

Adela Fernandez, Yannick Bahé, Nina Hatch +4

We investigate whether the intracluster light (ICL) can serve as a reliable tracer of the shape of the underlying dark matter (DM) haloes in galaxy clusters. Using the cosmological…

Intracluster light is a biased tracer of the dark matter distribution in clusters

J. Butler, G. Martin, N. A. Hatch +3

The diffuse stellar component of galaxy clusters known as intracluster light (ICL) has been proposed as an observable tracer of the cluster's dark matter (DM) halo. Assessing its r…

Stellar stripping efficiencies of satellites in numerical simulations: the effect of resolution, satellite properties and numerical disruption

G. Martin, F. R. Pearce, N. A. Hatch +3

The stellar stripping of satellites in cluster haloes is understood to play an important role in the production of intracluster light. Increasingly, cosmological simulations have b…
