Diversity in the stellar velocity dispersion profiles of a large sample of brightest cluster galaxies z ≤ 0.3
(Oxford Univ Press, 2018)We analyse spatially resolved deep optical spectroscopy of brightestcluster galaxies (BCGs) located in 32 massive clusters with redshifts of 0.05 ≤ z ≤ 0.30 to investigate their velocity dispersion profiles. We compare ... -
Dynamical masses of brightest cluster galaxies. I. Stellar velocity anisotropy and mass-to-light ratios
(Oxford Univ press, 2020)We investigate the stellar and dynamical mass profiles in the centres of 25 brightest cluster galaxies (BCGs) at redshifts of 0.05 ≤ z ≤ 0.30. Our spectroscopy enables us to robustly measure the Gauss–Hermite higher order ... -
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 ... -
Neutral hydrogen and magnetic fields in M83 observed with the SKA Pathfinder KAT-7
(Oxford Univ Press, 2016)We present new KAT-7 observations of the neutral hydrogen (H i) spectral line, and polarized radio continuum emission, in the grand-design spiral M83. These observations provide a sensitive probe of the outer-disc structure ...
