The extremely populated globular cluster system of the lenticular galaxy NGC 6861
(Wiley Blackwell Publishing, Inc, 2015-05)
We present a photometric study of the globular cluster (GC) system associated with the lenticular galaxy (S0) NGC 6861, which is located in a relatively low density environment. It is based on Gemini/GMOS images in the ...
Accretion of galaxy groups into galaxy clusters
(Wiley Blackwell Publishing, Inc, 2020-11)
We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their ...
Specific Frequencies and Luminosity Profiles of Cluster Galaxies and Intracluster Light in Abell 1689
(IOP PUBLISHING LTD, 2017)
We present magnitudes and profile fits for 180 galaxies in the central field of the massive lensing cluster Abell 1689 using very deep imaging with the Hubble Space Telescope Advanced Camera for Surveys in the F814W bandpass. ...
