About Me

I am a CATA Postdoctoral Researcher at Pontificia Universidad Católica de Chile (PUC), working on the ChANGES 4MOST Survey. My current research interests include multiphase AGN-driven outflows (ionized, molecular) and the characterization of their hosts through SED fitting.

During my previous research as a Fondecyt Postdoctoral Fellow at Universidad de Antofagasta (UA) and Universidad Diego Portales (UDP), Chile, I led the MUSE-ALMA multiphase outflow project in a subsample of local hard X-ray selected AGN from the Bat AGN Spectroscopy Survey (BASS). Additionally, I led a detailed characterization of the host galaxies in the complete BASS DR2.

I obtained my PhD in Astrophysics at the Universidad Andrés Bello (UNAB, Chile) in 2019, spending the two last years as an ESO Student in ESO Chile. It was addressed under the supervision of Dr. Isabelle Gavignaud (UNAB, Chile) and Dr. Eleonora Sani (ESO, Chile), and focuses on the analysis of optical spectra to unveil and characterize ionized outflows in the BASS hard X-ray AGN sample. The incidence of ionized outflows, their velocities, extensions, kinetics and how they relate with AGN properties are crucial to understanding galaxy evolution. Nonetheless, to truly study the effect of AGN driven outflows in feedback processes able to quench or generate local star formation (SF), a multi-wavelength study of outflows is needed to have a complete idea of their properties in the different phases of gas.

I obtained my BSc and MSc degrees at the Pontificia Universidad Católica de Chile (PUC).
