Metal-rich, Metal-poor: Updated Stellar Population Models for Old Stellar Systems [PDF]
, 2018 We present updated stellar population models appropriate for old ages (>1 Gyr) and covering a wide range in metallicities (−1.5 ≲ [Fe/H] ≲ 0.3). These models predict the full spectral variation associated with individual element abundance variation as a ...

A Study of Primordial Very Massive Star Evolution
The Astrophysical Journal, 2023 We present new evolutionary models of primordial very massive stars with initial masses ranging from 100 to 1000 M _⊙ that extend from the main sequence to the onset of dynamical instability caused by the creation of electron–positron pairs during core C,

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 ...

LATIS: The Stellar Mass–Metallicity Relation of Star-forming Galaxies at z ∼ 2.5
The Astrophysical Journal, 2023 We present the stellar mass–stellar metallicity relation for 3491 star-forming galaxies at 2 ≲ z ≲ 3 using rest-frame far-ultraviolet spectra from the Ly α Tomography IMACS Survey (LATIS).

Stellar populations in superclusters of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 A catalogue of superclusters of galaxies is used to investigate the influence of the supercluster environment on galaxy populations, considering galaxies brighter than M ...

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.

Nebular Continuum and Line Emission in Stellar Population Synthesis Models [PDF]
, 2016 Accounting for nebular emission when modeling galaxy spectral energy distributions (SEDs) is important, as both line and continuum emissions can contribute significantly to the total observed flux.

Unresolved versus resolved: testing the validity of young simple stellar population models with VLT/MUSE observations of NGC 3603 [PDF]
, 2016 CONTEXT. Stellar populations are the building blocks of galaxies including the Milky Way. The majority, if not all extragalactic studies are entangled with the use of stellar population models given the unresolved nature of their observation ...
