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).

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 ...

The SWIRE-VVDS-CFHTLS surveys: stellar mass assembly over the last 10 Gyears. Evidence for a major build up of the red sequence between z=2 and z=1 [PDF]

, 2007
(abridged abstract) We present an analysis of the stellar mass growth over the last 10 Gyrs using a large 3.6$\mu$ selected sample. We split our sample into active (blue) and quiescent (red) galaxies.

The detection of an older population in the Magellanic Bridge [PDF]

, 2013
The Magellanic system comprises the Large Magellanic Cloud (LMC), the Small Magellanic Cloud (SMC), and the less frequently observed Magellanic Bridge and Magellanic Stream. The Bridge is traced by neutral gas and has an observed stellar component, while

Stellar population gradients in Seyfert 2 galaxies. Northern sample [PDF]

, 2002
We use high signal-to-noise ratio long-slit spectra in the 3600-4700A range of the twenty brightest northern Seyfert 2 galaxies to study the variation of the stellar population properties as a function of distance from the nucleus.

A study of stellar population of intermediate-age globular cluster NGC 2249

Results in Physics, 2020
The Large Magellanic Cloud (LMC) star cluster NGC 2249 has been found to exhibit an extended main-sequence turn-off (eMSTO) in the color-magnitude diagram (CMD) derived from the data of the Hubble Space Telescope (HST).

On surface brightness fluctuations: probabilistic and statistical bases I: Stellar population and theoretical SBF

, 2008
This work aims to provide a theoretical formulation of Surface Brightness Fluctuations (SBF) in the framework of probabilistic synthesis models, and to distinguish between the different distributions involved in the SBF definition.

Stellar populations in HII galaxies [PDF]

Proceedings of the International Astronomical Union, 2004
We analyse the stellar content of a large number of HII galaxies from the continua and absorption features of their spectra using population synthesis methods, in order to gain information about the star formation histories of these objects. We find that all galaxies of our sample contain an old stellar population (>= 1 Gyr) that dominates the ...

The AIMSS Project – III. The stellar populations of compact stellar systems [PDF]

Monthly Notices of the Royal Astronomical Society, 2015
In recent years, a growing zoo of compact stellar systems (CSSs) have been found whose physical properties (mass, size, velocity dispersion) place them between classical globular clusters (GCs) and true galaxies, leading to debates about their nature. Here we present results using a so far underutilized discriminant, their stellar population properties.

Binary Stellar Population Synthesis Model

, 2010
Using Yunnan evolutionary population synthesis (EPS) models, we present integrated colours, integrated spectral energy distributions (ISEDs) and absorption-line indices defined by the Lick Observatory image dissector scanner (Lick/IDS) system, for an ...
