El fenómeno de la dispersión del litio fotosférico en las estrellas jóvenes de temperaturas super ciales Teff < 5500 K ha sido ampliamente estudiado, sin embargo no se ha establecido una explicación de nitiva. Estudios de ...
Benchmarking the infrared dark cloud G351.77-0.53: Gaia DR3 distance, mass distribution, and star formation content.
(Universidad de Concepción.Facultad de Ciencias Físicas y Matemáticas, 2023)
While intensively studied, it remains unclear how the star formation (SF) in Infrared Dark Clouds (IRDCs) compares to that of nearby clouds. We study G351.77-0.53 (henceforth G351), a cluster-forming filamentary IRDC. We ...
Artificial Intelligence in astronomy: machine learning and deep learning approaches to DESI data
(Universidad de los AndesDoctorado en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2023-07-11)
Artificial Intelligence (AI) has shown promise in advancing fundamental physics knowledge, from particle physics to cosmology. The significant advancements in AI over the last decade have been increasingly applied to solve ...
Unsupervised machine learning for the classification of astrophysical X-ray sources
Context. The Chandra Source Catalog (CSC), which collects the X-ray sources detected by the Chandra X-ray Observatory through its history, is a fertile ground for discovery, because many of the sources it contains have not ...
