Abstract: Using a semi-analytical model of the evolution of the Milky Way, we show how secular evolution can create distinct overdensities in the phase space of various properties (e.g. age vs metallicity or abundance ratios vs… read more here.

DOI: 10.1093/mnras/stw2407
Abstract: We present a joint analysis of the four most prominent sodium-sensitive features (Na D, Na I λ8190A, Na I λ1.14 μm, and Na I λ2.21 μm), in the optical and near-infrared spectral ranges, of two… read more here.

DOI: 10.1093/mnras/stx3254
Abstract: We determine abundance ratios of 37 dwarf ellipticals (dEs) in the nearby Virgo cluster. This sample is representative of the early-type population of galaxies in the absolute magnitude range -19.0 read more here.
