TL;DR: In this paper, a review of the state-of-the-art in galaxy population modeling is presented, including the treatment of the Thermally-Pulsating Asymptotic Giant Branch phase, evidences of an unusual Initial Mass Function, and the effect of modern stellar libraries on the model spectral energy distribution.

Abstract: Modelling 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 high-redshift. These are the treatment of the Thermally-Pulsating Asymptotic Giant Branch phase, evidences of an unusual Initial Mass Function, and the effect of modern stellar libraries on the model spectral energy distribution.

Master thesis : Rotation Curve of the Spiral Galaxy NGC 7331 from the Luminosity and Mass Profiles
Andrea Lopez Lopez
- 24 Jan 2019
TL;DR: In this paper, the rotation curve of the spiral galaxy NGC 7331 from its luminosity profile was calculated from 14 images of different spectral bands (from the far ultraviolet to the far infrared) to obtain the flux for the different distances to the galactic center, and for each spectral band, the luminosity profiles were then corrected for dust absorption.

- 12 Jun 2013
TL;DR: In this paper, the mass-size evolution of galaxies from z=7 to z=1 was studied and the robustness of size measurement techniques for z = 0 and z = 1 galaxies was studied in details.
Comparative Studies of Population Synthesis Models in the Framework of Modified Strömgren Filters
TL;DR: In this article, the authors investigate the technique of modified Stromgren photometry to measure reliable parameter-sensitive colours and estimate precise model ages and metallicities, and compare the results with the Rakos/Schulz models with GALEV and Worthey's Lick/IDS model.
Structure of disk-dominated galaxies. ii. color gradients and stellar population models
TL;DR: In this article, the authors investigate optical and near-IR color gradients in a sample of 172 low-inclination galaxies spanning Hubble types S 0-Irr and find strong correlations in age and metallicity with Hubble type, rotational velocity, total magnitude, and central surface brightness in the sense that earlier-type, faster rotating, more luminous and higher surface brightness galaxies are older and more metal-rich, suggesting an early and more rapid star formation history for these galaxies.
