ESO Talk
Lecture — Crafting effective outreach activities
Sofía Otero (ESO)
View Abstract
Abstract
What makes some outreach materials or activities hit the mark while others fall flat? In this talk, we'll dive into content presentation, have open discussions, and reflect on our approaches. The goal is to help you think critically about designing outreach activities with clear objectives, so you can really see if your efforts are paying off.

Talk — Introducing SIESTA: a new CMD fitting code
Bernardo P. L. Ferreira (Universidade Federal de Minas Gerais)
View Abstract
Abstract
In this talk, I’ll introduce a new, public code for performing isochrone fitting to the color-magnitude diagram of star clusters, named SIESTA (Statistical matchIng between rEal and Synthetic sTellar populAtions). In particular, I’ll show applications of the method in the context of the Large Magellanic Cloud, using data from the VISCACHA Survey, highlighting how determining reliable ages, metallicities and distances for star clusters within this galaxy is important for understanding some of its signature features, such as the age-metallicity relation and its 3-dimensional structure.

Talk — Metal enrichment across the Baryon cycle
Magdalena Hamel
View Abstract
Abstract
The metal enrichment across the baryon cycle of galaxies is crucial for understanding galaxy evolution. Supernovae expel metal rich gas away from galaxies and inflows inject pristine gas. Simulations show that outflows are the main mechanism in redistributing metals and are key drivers of the chemical enrichment of galaxies and their circumgalactic medium. However, measuring metal abundance is challenging and therefore direct observations are almost completely lacking from the literature. I will present results from ESO/X-shooter, ESO/MUSE and Keck/KCWI where we measure outflow metallicities by detecting the very faint [O III] 4363 auroral line, a robust metallicity tracer, in both the disk and outflow of a sample of galaxies. These observations allow us to estimate the metal loading factor, a critical parameter for realistic simulations and compare with results from absorption line analysis and to recent simulations of metal-enrichment in winds.

Lecture — The Alchemists - How the stars made the periodic table
Luca Sbordone (ESO)
View Abstract
Abstract
When the Universe begun, its chemical composition was very simple: only Hydrogen, Helium and Lithium were produced in the Big Bang nucleosynthesis. Almost all the other chemical elements were subsequently synthesized by nuclear reactions in stars, through a network of different reactions whose outcome depends on stellar mass and composition. Different release mechanisms, different stellar evolutionary timescales, and the complexity of yield mixing with the existing gas that would then form new stars produce strikingly different abundance evolution patterns for different elements. Since detailed abundances for many tens of elements can be derived from stars and interstellar/intergalactic gas, they provide a powerful tool to understand the past evolution of our Galaxy, and of galaxies in general, as far back as the first star formation episodes after the Big Bang. I will try to outline what we know about nucleosynthesis, how it produces the chemistry we see now in the Universe, and how it can be exploited to understand stellar and galactic evolution.
