Estimadas/os,

hoy tenemos el gusto de contar con una charla a cargo de Lucas 
Valenzuela, quien es estudiante de doctorado de la LMU de Múnich, y está 
realizando una breve estadía en el IALP. El seminario se llevará a cabo 
en el Salón Meridiano, a las 12:30 hs. Como siempre, habrá café (traer 
sus propias tazas) y algo dulce para compartir.

Abajo encontrarán el título y resumen.

Les dejo un cordial saludo,

Dr. Favio R. Faifer
Director
Instituto de Astrofísica de La Plata

Título de la charla: What’s Your Story? Deciphering galaxy formation 
histories from present-day properties

Abstract: Since almost 100 years it has been known that our Milky Way is 
not the only island of stars in the Universe. Many other galaxies have 
since been found, featuring an immense variety of properties. Diverse 
morphologies, kinematics, and structures in their outskirts indicate 
that galaxies can have very different formation pathways. Over the 
years, our general understanding of galaxy evolution has improved 
through an increasing amount of observations and simulations. But what 
about an individual galaxy? What possibilities do we have to decipher 
the formation history of a single galaxy from its observed present-day 
properties? Using a broad range of observables in galaxies and comparing 
them between observations and simulations, I will present how these can 
be related to the formation histories of galaxies and thus be used as 
indicators for an individual galaxy’s past. Specifically, I will show 
what information is encoded in the inner kinematics of galaxies, the low 
surface brightness structures found in their outskirts, and in the 
properties of so-called tracer populations: globular clusters and 
planetary nebulae. Finally, I will give an overview of the ongoing work 
of bringing planetary nebulae into cosmological simulations for the 
first time, which will enable a direct comparison with observations and 
provide more insight into the underlying stellar populations and star 
formation histories.
