Constraining the dark matter density in galaxy clusters
(PoS, 2015)
We illustrate the potential of using stellar velocity dispersion profiles of brightest cluster galaxies
(BCGs), in combination with X-ray and weak-lensing derived cluster mass profiles, to constrain
the matter distribution ...
The detailed nature of active central cluster galaxies
(South African Institute of Physics, 2014)
We present detailed IFU observations of the central few kiloparsecs of the ionised nebulae surrounding four active central cluster galaxies in cooling flow clusters. All four galaxies have Hα filaments, and existing data ...
Investigating brightest cluster galaxies: kinematics with SALT
(South African Institute of Physics, 2014)
We present detailed, high spatial and spectral resolution, longslit observations of
four active central cluster galaxies (CCGs) in cooling flow clusters (Abell 0085, 0133, 0644 and
Ophiuchus). Our sample consists of CCGs ...
An overview of the MHONGOOSE survey: observing nearby galaxies with MeerKAT

Investigating the hot gas in active brightest cluster galaxies
(PoS, 2016)
We investigate a crucial phase in the cooling–feedback cycle in the star forming Brightest Clus-
ter Galaxies (BCGs) by looking at the optical emission line properties of the reheated gas that
ultimately causes the cycle ...
The MeerKAT Fornax survey
(Sissa Medialab, 2016)
We present the science case and observations plan of the MeerKAT Fornax Survey, an H
I
and
radio continuum survey of the Fornax galaxy cluster to be carried out with the SKA precursor
MeerKAT. Fornax is the second most ...
Dynamical modelling of brightest cluster galaxies: constraints on the IMF
(Cambridge Univ Press, 2020)
We study the stellar and dynamical masses, as well as the stellar populations, of brightest cluster galaxies (BCGs) located in 32 massive clusters, and for a sub-sample of these use the results to place constraints on the ...
Stellar and dynamical masses of brightest cluster galaxies
(Cambridge Univ Press, 2020)
We investigate the stellar and dynamical mass profiles of 32 brightest cluster galaxies (BCGs, MK = −25.7 to −27.8 mag) in massive clusters (0.05 < z < 0.30), and in particular the rising velocity dispersion profiles of ...
