The central stellar populations of brightest cluster galaxies
(North-West University, 2012)The majority of galaxy clusters contain a massive galaxy in the centre of the clusters that are far more luminous and massive than the other galaxies in the cluster. These galaxies are called the brightest galaxy clusters ... -
Kinematics and star formation histories of brightest cluster galaxies
(North-West University (South Africa), 2023)Brightest cluster galaxies (BCGs) are the most massive and luminous galaxies in the Universe. In this work we study BCGs at intermediate redshifts (0.3 < z < 0.8) to provide more observational insights on the BCG formation ... -
Kinematics and stellar populations of dwarf elliptical galaxies
(North-West University, 2018)Galaxy clusters serve as ideal laboratories to address the fundamental question of how environmental influence governs galaxy formation and evolution. They predominantely host elliptical and lenticular (early-type) ... -
Optical Spectroscopy of Galaxies in the CLoGS and MHONGOOSE Surveys
(North-West University (South Africa), 2023)The majority of observable galaxies within the local Universe can be found within group environments. Roughly at the centre of each galaxy group’s gravitational potential well lies each group’s brightest and most massive ... -
Star formation histories of brightest group galaxies in CLoGS
(North-West University (South Africa), 2020)An important component of galaxy formation and evolution studies, is to accurately constrain the star formation histories (SFHs) of galaxies. While the SFHs of most massive early-type galaxies can be described using a ...
