Constraining the dark matter density in galaxy clusters
Loubser, S.I.; Donahue, M.; Voit, M. (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 ... -
Investigating the hot gas in active brightest cluster galaxies
Ratsimbazafy, A.L.; Loubser, S.I.; Donahue, M.; Voit, G.M. (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 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 ...
