I am a CATA postdoctoral fellow at Pontificia Universidad Católica de Chile (PUC), working on the ChANGES survey, which will be observed with the 4MOST instrument. Previously, I was a FONDECYT Fellow (2021–2024) and an ESO Student (2017–2019). My main research focuses on understanding how the activity of supermassive black holes in the centers of galaxies can affect star formation in their host galaxies. To achieve this, I use IFU data from MUSE and ALMA to characterize the outflowing material from the AGN and the molecular gas available for future star formation. I also use multi-wavelength data, from X-ray to far-infrared, to disentangle the emissions of AGN from those of their host galaxies. In my free time, I'm a mentor at the PROVOCA program, an AUI/NRAO initiative that aims to increase the participation, retention and promotion of women and other underrepresented minorities in STEM. I enjoy sports and relaxing through watercolor painting, continually learning new techniques. I've also started a watercolor workshop to teach astronomy through art (https://www.instagram.com/astroaquarela_/) that is now supported by the “Crear Salud” project at Universidad de Antofagasta. |
Ana Maria Jimenez Gallardo |
I am an ESO Research Fellow with duties in Paranal. I have been at ESO, Santiago, for a total of two years, one year as a Fellow and one year as a Student. My science focuses on the study of radio-loud AGN, which are those hosting the most massive black holes among AGN and displaying powerful radio jets. In particular, my research focuses on the impact radio jets have on the environment to understand how this interaction can affect AGN and host galaxy evolution. To do that, I use multifrequency observations of these sources, from the radio to the X-rays. Operationally, my work focuses on the instruments located in UT4, MUSE, HAWK-I, and, especially, ERIS. I enjoy traveling, reading, drawing, painting, and crafting, although I spend most of my time playing video games and listening to true crime podcasts. |

I am an ESO Research Fellow with duties at Paranal Observatory. I love meteorites and, for this reason, my research focuses on identifying their asteroid parent bodies using large optical and near-infrared telescopes. These powerful facilities enable me to measure the reflectance spectra, three-dimensional shapes, and densities of asteroids. By analyzing this data, I aim to establish genetic links between meteorite samples and asteroid populations and thus provide a better understanding of the original composition gradient within our own protoplanetary disk. On the operations side, I specialize in adaptive-optics-fed instruments such as ERIS, MUSE, HAWK-I, and SPHERE, as well as spectrographs like X-SHOOTER and CRIRES. My career has taken me to various institutions around the world, including in France (my home country), Canada, Spain, Northern Ireland, the U.S., and Chile. Outside of research, I like traveling, music, volleyball, bouldering, swimming, and (free)diving. Above all, I love sharing my enthusiasm for space rocks and science. I look forward to meeting you at the La Silla summer school! |

I am an ESO staff astronomer working at ESO headquarters in Garching, Germany, since many years. In my daily work I provide support to the users of ESO Paranal Observatory instruments to ensure that they have everything at hand and prepared to get the best science results from their observations. My main expertise is in the area of infrared and optical imaging, also using high spatial resolution adaptive optics techniques, as well as in multi-object spectroscopy. Scientifically I work in the area of star formation, in our galaxy and in the nearby Magellanic Clouds dwarf galaxies. With data from a variety of instruments and taken from optical to radio wavelength, I am trying to understand how brown dwarfs and planetary mass objects form, how stellar binarity affects the evolution of protoplanetary discs, or how young clusters and OB associations emerge from large molecular clouds. |

I'm an ESO staff astronomer working at Paranal where I am instrument scientist for ERIS, a combined near-infrared imager and integral field spectrograph that was recently commissioned on UT4. My main research focus is in the use of high-angular resolution observing techniques to detect and characterize companions to nearby stars, primarily substellar companions that lie below the hydrogen burning limit. I'm also interested in the synergy between this direct detection technique and other indirect techniques such as radial velocity and astrometry. In my free time I relax by playing video games, both single-player and with (and against) my friends in multi-player. I also really enjoy watching and reading about history, recent and contemporary politics, and, of course, science fiction. |
