Two new young astronomers on their way
Ignacio Muñoz and Valentina Miranda successfully defended their master thesis in March 2026. Both of them come out with excellent works with interesting results to be published and already published. Valentina started a new line of collaborations with observers to understand the star formation process in the early universe by envisaging a methodology to confront observations with simulations, soon to be sent to publication. Simulations offer the possibility to investigate hy

Jenny Gonzalez, PhD done!
Stellar halos —the faint envelopes of stars surrounding galaxies— are true cosmic archives. They preserve chemical and dynamical signatures that reveal how each galaxy formed and evolved. However, studying them beyond the Milky Way is challenging due to their extremely low surface brightness. In this research, we used the CIELO cosmological zoom-in simulations to explore how stellar halos assemble across a wide range of galaxy masses. We analyzed their chemical abundances ,
