Astrocharlas: “Understanding Galaxies in 3D”

The University of Arizona is proud to present Astrocharlas, the exciting and educational Spanish lecture series covering an array of important Astronomy topics. Astrocharlas is the first public talk series at the College of Science done entirely in Spanish. It is free and open to the public of all ages and currently runs once a semester.

The fall 2021 Astrocharlas presentation titled “Understanding Galaxies in 3D” will be on Tuesday, December 7. Currently, Astrocharlas is live-streamed on YouTube (youtu.be/6FaKavzYDQg), with the hope to return to in-person talks in the coming year.

This semester’s speaker is Dr. Jorge Barrera-Ballesteros from Universidad Nacional Autónoma de México (UNAM). Dr Barrera-Ballesteros earned his PhD at Johns Hopkins University and is an expert in studying the makeup and evolution of galaxies using a novel technique known as “resolved spectroscopy”. Dr. Barrera-Ballestero has provided a short blurb on his talk in English:

“A galaxy is made of billions of stars, gas, dust, and dark matter. They are also the bricks that the universe is made of. In this talk, I will describe how we use a novel observational technique to see galaxies in a '3D' fashion. I will also highlight why these observations are essential for us in order to have a better understanding on how galaxies form and evolve.”

Following the 30-40 minute talk, Dr. Barrera-Ballesteros will be taking questions from the audience. We hope to see you there!
