The Auriga stellar haloes: Connecting stellar population properties with accretion and merging history
(Monthly Notices of the Royal Astronomical Society, 2019-02-15)
We examine the stellar haloes of the Auriga simulations, a suite of 30 cosmological magnetohydrodynamical high-resolution simulations of Milky Way-mass galaxies performed with the moving-mesh code AREPO. We study halo ...
Observational hints of radial migration in disc galaxies from CALIFA
(EDP Sciences, 2017-08)
According to numerical simulations, stars are not always kept at their birth galactocentric distances but they have a tendency to migrate. The importance of this radial migration in shaping galactic light distributions is ...
Galaxy And Mass Assembly (GAMA): the signatures of galaxy interactions as viewed from small-scale galaxy clustering
(2018)
Statistical studies of galaxy-galaxy interactions often utilize net change in physical properties of progenitors as a function of the separation between their nuclei to trace both the strength and the observable time-scale ...
IFU spectroscopy of 10 early-type galactic nuclei – II. Nuclear emission line properties
(Oxford University PressOxford, 2014)
Although it is well known that massive galaxies have central black holes, most of them
accreting at low Eddington ratios, many important questions still remain open. Among them
are the nature of the ionizing source, the ...
The Gaia–ESO Survey: Carbon Abundance in the Galactic Thin and Thick Disks
(The American Astronomical Society, 2020)
This paper focuses on carbon, which is one of the most abundant elements in the universe and is of high importance in the field of nucleosynthesis and galactic and stellar evolution. The origin of carbon and the relative ...
LoCuSS: the slow quenching of star formation in cluster galaxies and the need for pre-processing
(IOP Publishing, 2015)
We present a study of the spatial distribution and kinematics of star-forming galaxies in 30 massive clusters at 0.15 < z < 0.30, combining wide-field Spitzer 24 mu m and GALEX near-ultraviolet imaging with highly complete ...
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 ...
