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.

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.

Synthetic stellar populations: single stellar populations, stellar interior models and primordial protogalaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We present a new set of stellar interior and synthesis models for predicting the integrated emission from stellar populations in star clusters and galaxies of arbitrary age and metallicity. This work differs from existing spectral synthesis codes in a number of important ways, namely (1) the incorporation of new stellar evolutionary tracks, with ...

Inflow, Outflow, Yields, and Stellar Population Mixing in Chemical Evolution Models [PDF]
, 2016 Chemical evolution models are powerful tools for interpreting stellar abundance surveys and understanding galaxy evolution. However, their predictions depend heavily on the treatment of inflow, outflow, star formation efficiency (SFE), the stellar ...

Star Formation History at the Centers of Lenticular Galaxies with Bars and Purely Exponential Outer Disks from SAURON Data [PDF]
, 2010 We have investigated the stellar population properties in the central regions of a sample of lenticular galaxies with bars and single-exponential outer stellar disks using the data from the SAURON integral-field spectrograph retrieved from the open Isaac

Stellar Population Models [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractModelling stellar populations in galaxies is a key approach to gain knowledge on the still elusive process of galaxy formation as a function of cosmic time. In this review, after a summary of the state-of-art, I discuss three aspects of the modelling, that are particularly relevant to massive galaxies, the focus of this symposium, at low and ...

The ATLAS3D Project – XXX. Star formation histories and stellar population scaling relations of early-type galaxies [PDF]
, 2015 We present the stellar population content of early-type galaxies from the ATLAS^(3D) survey. Using spectra integrated within apertures covering up to one effective radius, we apply two methods: one based on measuring line-strength indices and applying ...
