Diversity in the stellar velocity dispersion profiles of a large sample of brightest cluster galaxies z ≤ 0.3
Loubser, S.I.; Hoekstra, H.; Babul, A.; O'Sullivan, E. (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 ... -
The regulation of star formation in cool-core clusters: imprints on the stellar populations of brightest cluster galaxies
Loubser, S.I.; Babul, A.; Hoekstra, H.; Mahdavi, A.; Donahue, M. (Oxford Univ Press, 2016)A fraction of brightest cluster galaxies (BCGs) show bright emission in the ultraviolet and the blue part of the optical spectrum, which has been interpreted as evidence of recent star formation. Most of these results ...
