Evidence for the universality of properties of red-sequence galaxies in x-ray- and red-sequence-selected clusters at z ∼ 1
(Institute of Physics Publishing, 2015-10)
We study the slope, intercept, and scatter of the color-magnitude and color-mass relations for a sample of 10 infrared red-sequence-selected clusters at z ∼ 1. The quiescent galaxies in these clusters formed the bulk of ...
Galaxy distribution and evolution around a sample of 2dF groups
(EDP SCIENCES S A, 2009)
Context. We study galaxy evolution and spatial patterns in the surroundings of a sample of 2dF groups. Aims. Our aim is to find evidence of galaxy evolution and clustering out to 10 times the virial radius of the groups ...
Velocity dispersion of brightest cluster galaxies in cosmological simulations
(Wiley Blackwell Publishing, Inc, 2021-11)
Using the DIANOGA hydrodynamical zoom-in simulation set of galaxy clusters, we analyse the dynamics traced by stars belonging to the brightest cluster galaxies (BCGs) and their surrounding diffuse component, forming the ...
Extra-tidal star candidates in globular clusters of the sagittarius dwarf spheroidal galaxy
(EDP Sciences, 2022-09)
Context. Globular clusters (GCs) associated with the Sagittarius dwarf spheroidal galaxy (Sgr dSph) have evolved under the gravita tional potential of both Sgr dSph and the Milky Way. The effects of these potentials are ...
