Elemental Abundances in M31: The Kinematics and Chemical Evolution of Dwarf Spheroidal Satellite Galaxies [PDF]
Astronomical Journal, 2019 We present deep spectroscopy from Keck/DEIMOS of Andromeda I, III, V, VII, and X, all of which are dwarf spheroidal satellites of M31. The sample includes 256 spectroscopic members across all five dSphs.

The star formation and chemical evolution history of the Fornax dwarf spheroidal galaxy [PDF]
, 2012 We have combined deep photometry in the B, V and I bands from CTIO/MOSAIC of the Sculptor dwarf spheroidal galaxy, going down to the oldest main sequence turn-offs, with spectroscopic metallicity distributions of red giant branch stars. This allows us to

PÉGASE.3: A code for modeling the UV-to-IR/submm spectral and chemical evolution of galaxies with dust [PDF]
Astronomy & Astrophysics, 2019 A code computing consistently the evolution of stars, gas and dust, as well as the energy they radiate, is required to derive reliably the history of galaxies by fitting synthetic spectral energy distributions (SEDs) to multiwavelength observations.

The Astrophysical Journal, 2023 Growing evidence in support of a connection between active galactic nuclei (AGN) activity and the ram pressure stripping (RPS) phenomenon has been found both observationally and theoretically in the past decades.

Chemical evolution of elliptical galaxies with a variable IMF [PDF]
Astronomy & Astrophysics, 2019 Growing evidence in recent years suggests a systematic variation of the stellar initial mass function (IMF), being top-heavy for starburst galaxies and possibly bottom-heavy for massive ellipticals.

Chemical evolution during gas-rich galaxy interactions [PDF]
, 2011 We perform and analyse a set of galaxy interactions performed by using a self-consistent chemo-hydrodynamical model which includes star formation, supernova (SN) feedback and chemical evolution.

Stellar populations in gas-rich galaxy mergers I. Dependence on star formation history
, 1998 We investigate the nature of stellar populations of major galaxy mergers between late-type spirals considerably abundant in interstellar medium by performing numerical simulations designed to solve both the dynamical and chemical evolution in a self ...

The Chemical Evolution of the Draco Dwarf Spheroidal Galaxy [PDF]
, 2009 We present an abundance analysis based on high resolution spectra of 8 stars selected to span the full range in metallicity in the Draco dwarf spheroidal galaxy. We find [Fe/H] for the sample stars ranges from -1.5 to -3.0 dex.

Star cluster formation in cosmological simulations – III. Dynamical and chemical evolution [PDF]
Monthly notices of the Royal Astronomical Society, 2018 In previous papers of this series, we developed a new algorithm for modeling the formation of star clusters in galaxy formation simulations. Here we investigate how dissolution of bound star clusters affects the shape of the cluster mass function and the
