The Intracluster Light of Abell 3667: Unveiling an Optical Bridge in LSST Precursor Data

The Astrophysical Journal Letters
Intracluster light (ICL), the diffuse glow of stars stripped from galaxies during a cluster’s formation, is an established tracer of a cluster’s dynamical history. The upcoming Vera C.

Stellar Populations of Brightest Cluster Galaxies and Intracluster Light

, 2016
We present 3 representative cases from a sample of 16 local Brightest Cluster Galaxies observed using integral field spectroscopy. The observations extend to nearby neighbours and into the Intracluster Light (ICL).

Evolution of Massive Red Galaxies in Clusters from z = 1.0 to z = 0.3

The Astronomical Journal
A critical issue in studying the evolution of galaxy clusters is to find ways that enable meaningful comparisons of clusters observed at different redshifts, as well as in various stages of their growth.

The star formation history of early-type galaxies in the fornax cluster [PDF]

, 1998
We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.

Did brightest cluster galaxies experience more than one star formation epoch? [PDF]

, 2012
We use the full spectrum fitting ability of ULySS, with the Pegase.HR stellar population model to fit the observed spectra of 40 brightest cluster galaxies in order to determine whether a single or a composite stellar population provided the most ...

Deep MOS Spectroscopy of NGC 1316 Globular Clusters

Galaxies, 2017
The giant elliptical galaxy NGC 1316 is the brightest galaxy in the Fornax cluster, and displays a number of morphological features that might be interpreted as an intermediate age merger remanent (∼3 Gyr).

Reexamination of the CO Absorption Line in the M87 Nucleus

The Astrophysical Journal
We analyzed the archival Atacama Large Millimeter/submillimeter Array data of the nuclear region of M87 and evaluated the molecular gas content from the CO(2–1) absorption line.

The clustering of galaxies in hierarchical galaxy formation models [PDF]

, 2010
Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.
