Galaxy clusters contain a diffuse stellar component outside the cluster’s galaxies, which is observed as faint intracluster light (ICL). Using Gemini/GMOS-N deep imaging and multiobject spectroscopy of a massive fossil cluster at a redshift of z = 0.47, RX J105453.3+552102 (J1054), we improve the observational constraints on the formation mechanism of the ICL. We extract the ICL surface brightness and colour profiles out to 155 kpc from the brightest cluster galaxy (BCG) with a detection… Expand


Measurement of the intracluster light at z ∼ 1
A significant fraction of the total photospheric light in nearby galaxy clusters is thought to be contained within the diffuse intracluster light (ICL), which extends hundreds of kpc from clusterExpand
Intracluster Light in Nearby Galaxy Clusters: Relationship to the Halos of Brightest Cluster Galaxies
We present a detailed analysis of the surface brightness distribution of the brightest cluster galaxy (BCG) in each of 24 galaxy clusters at 0.03 < z < 0.13. We use two-dimensional profile fitting toExpand
Intracluster light: a luminous tracer for dark matter in clusters of galaxies
The bulk of stars in galaxy clusters are confined within their constituent galaxies. Those stars do not trace the extended distribution of dark matter well as they are located in the central regionsExpand
Diffuse Light in the Virgo Cluster
We present deep optical imaging of the inner 1.5 x1.5 of the Virgo cluster to search for diffuse intracluster light (ICL). Our image reaches a 1 depth of µv=28.5 mag/arcsec 2 — 1.5 mag/arcsec 2Expand
Theoretical Predictions of Colors and Metallicity of the Intracluster Light
We study colors and metallicities of the Brightest Cluster Galaxies (BCGs) and Intra-Cluster Light (ICL) in galaxy groups and clusters, as predicted by a semi-analytic model of galaxy formation,Expand
JD2 - Diffuse Light in Galaxy Clusters
Abstract Diffuse intracluster light (ICL) has now been observed in nearby and in intermediate redshift clusters. Individual intracluster stars have been detected in the Virgo and Coma clusters andExpand
Deep CCD Surface Photometry of Galaxy Clusters. II. Searching for Intracluster Starlight in Non-cD clusters
We report the search for intracluster light in four Abell type II-III (non-cD) galaxy clusters: A801, A1234, A1553, and A1914. We find that on average these clusters contain ~10% of their detectedExpand
Specific Frequencies and Luminosity Profiles of Cluster Galaxies and Intracluster Light in Abell 1689
We present magnitudes and profile fits for 180 galaxies in the central field of the massive lensing cluster Abell 1689 using very deep imaging with the ACS/HST in the F814W bandpass. Previous workExpand
The growth of intracluster light in XCS-HSC galaxy clusters from 0.1 < z < 0.5
We estimate the Intracluster Light (ICL) component within a sample of 18 clusters detected in XMM Cluster Survey (XCS) data using deep (∼ 26.8 mag) Hyper Suprime Cam Subaru Strategic Program DR1Expand
Evidence for the Existence of Abundant Intracluster Light at z = 1.24
Intracluster stars are believed to be unbound from their progenitor galaxies and diffused throughout the galaxy cluster, creating intracluster light (ICL). However, when and how these stars form areExpand
