On the stellar populations of massive galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2012 Abstract In this Letter, we analyse the predicted physical properties of massive galaxies, in the framework of recent semi-analytic models of galaxy formation. All models considered account for winds driven by supernova explosions and suppression of gas condensation at the centre of relatively massive haloes by active galactic nuclei ...

SDSS-IV MaNGA: global stellar population and gradients for about 2000 early-type and spiral galaxies on the mass-size plane [PDF]
, 2018 We perform full spectrum fitting stellar population analysis and Jeans Anisotropic modelling (JAM) of the stellar kinematics for about 2000 early-type galaxies (ETGs) and spiral galaxies from the MaNGA DR14 sample.

A 3D view of the Hyades stellar and sub-stellar population [PDF]
Astronomy & Astrophysics, 2019 Aims. Our scientific goal is to provide a 3D map of the nearest open cluster to the Sun, the Hyades, combining the recent release of Gaia astrometric data, ground-based parallaxes of sub-stellar member candidates and photometric data from surveys which ...

Distribution and Evolution of Metals in the Magneticum Simulations
Galaxies, 2017 Metals are ideal tracers of the baryonic cycle within halos. Their composition is a fossil record connecting the evolution of the various stellar components of galaxies to the interaction with the environment by in- and out-flows.

Stellar Population Variations in the Milky Way's Stellar Halo [PDF]
, 2010 If the stellar halos of disk galaxies are built up from the disruption of dwarf galaxies, models predict highly structured variations in the stellar populations within these halos.

Investigation of the Stellar Population of Several Polar Ring Galaxies
Galaxies, 2016 We present results of our investigation of two multi-spin galaxies which were taken from the catalog of polar ring galaxies. All of them possess nucleus-like knots.
