Applications of Stellar Population Synthesis in the Distant Universe

Galaxies, 2020
Comparison with artificial galaxy models is essential for translating the incomplete and low signal-to-noise data we can obtain on astrophysical stellar populations to physical interpretations which describe their composition, physical properties ...

Stellar Population Properties in the Stellar Streams around SPRC047

The Astrophysical Journal
We have investigated the properties (e.g., age, metallicity) of the stellar populations of a ringlike tidal stellar stream (or streams) around the edge-on galaxy SPRC047 ( z = 0.031) using spectral energy distribution (SED) fits to ...

Evolutionary population synthesis for binary stellar populations [PDF]

Astronomy & Astrophysics, 2004
We present integrated colours, integrated spectral energy distributions, and absorption-line indices, for instantaneous burst solar-metallicity binary stellar populations with ages in the range l-15Gyr.

Stellar populations with ELTs [PDF]

Proceedings of the International Astronomical Union, 2005
The star formation, mass assembly and chemical enrichment histories of galaxies, and their present distributions of dark matter, remain encoded in their stellar populations. Distinguishing the actual distribution functions of stellar age, metallicity and kinematics at several locations in a range of galaxies, sampling across Hubble types and ...

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 Stellar Population of M17

The Astrophysical Journal, 2008
The stellar content of M17 has been investigated by multicolor photometry and spectroscopy. Various independent estimates yield a distance of 2.1 ± 0.2 kpc. The ratio of total-to-selective extinction is R = 3.9. Within a projected area of 3.6 × 3.7 pc, there are several thousand stars.
