Exploring the Universe through Data and Machine Learning

About Me

Luis Angel Gutiérrez Soto

Welcome! I'm Luis Angel Gutiérrez Soto, an astrophysicist passionate about understanding the universe through observational data. Born in Valledupar, Colombia, I grew up between the Serranía del Perijá, Manaure Cesar and Valledupar. My academic journey has taken me across Latin America, enriching my perspective on science and collaboration.

Currently, I'm a postdoctoral researcher at the Instituto de Astrofísica de La Plata (CONICET-UNLP), where I focus on identifying planetary nebulae, symbiotic stars and other interesting and rare astronomical objects using multi-band photometric surveys and developing machine learning classification algorithms.

My research bridges traditional astronomical observation with modern data science techniques, working with large surveys like S-PLUS and J-PAS to uncover hidden astrophysical objects and understand stellar evolution processes.

Beyond science, I find inspiration in literature and philosophy, particularly in the magical realism of Gabriel García Márquez, which reminds me that wonder and discovery exist at the intersection of science and imagination, with One Hundred Years of Solitude being my favorite novel of all time.

James Webb Space Telescope

The James Webb Space Telescope represents a new era in astronomical observation, allowing us to study planetary nebulae and other celestial objects with unprecedented detail and sensitivity. Its infrared capabilities reveal hidden structures and chemical compositions that were previously invisible to other telescopes.

My research with large photometric surveys like S-PLUS complements JWST observations by identifying candidate objects for detailed study and providing contextual data across multiple wavelengths.

Research Interests

Planetary Nebula Research

Planetary Nebulae

Discovering and studying planetary nebulae - the beautiful final stages of Sun-like stars - using innovative color selection methods in large surveys like Gaia and Pan-STARRS, with confirmation from LAMOST spectroscopy.

Machine Learning Applications

AI for Stellar Astrophysics

Using artificial intelligence and S-PLUS multi-band photometry to map the chemical composition of millions of stars across the Milky Way. Our methods reveal how elements are distributed and help us understand the formation history of our galaxy.

Large Surveys

Rare Emission-Line Objects

Discovering rare cataclysmic variables by their unique colors in S-PLUS and confirming them with large telescopes like Gemini and Swift. This approach reveals hidden populations of accreting white dwarfs that are difficult to find with other methods.
