SUMMARY:Deep Learning for Small Astrophysical Datasets: From Cosmology to Exoplanet Detection
DESCRIPTION:Deep learning is increasingly revolutionizing astrophysics by enabling advanced analysis of complex and high-dimensional datasets. However\, the application of these methods is often limited by data availability and noise\, requiring careful model design\, optimization\, and regularization to balance performance and robustness. \nThis talk presents recent research addressing these challenges\, including deep learning techniques for cosmological parameter reconstruction\, the use of genetic algorithms to optimize neural networks and improve precision\, and the combination of these methods to accelerate Bayesian inference. It then focuses on applications to the detection of Earth-like exoplanets using stellar radial-velocity measurements\, where stellar activity and instrumental effects dominate the signal. In particular\, deep learning models trained directly on real high-resolution stellar spectra are shown to recover tiny Doppler shifts in unseen data\, approaching the precision required for the detection of terrestrial planets. \nThe seminar aims to provide practical insights into the effective use of deep learning for astrophysical problems in which data are limited\, and precision is crucial. \nFecha y lugar: 19/02/2026 – 12:30 | Salón de ActosIsidro Gómez VargasIAA-CSIC \n  \n

SUMMARY:Un viaje por Marte
DESCRIPTION:Marte\, el planeta rojo\, ha despertado la fascinación de la humanidad desde los primeros tiempos. \nEn esta charla trataremos de ponernos en la piel de un hipotético futuro viajero por Marte para descubrir cuáles son las condiciones que afrontaría en la superficie del planeta. \nRepasaremos también la historia de la exploración espacial de Marte y discutiremos algunas de las preguntas abiertas sobre nuestro planeta vecino. \nFecha: 26/02/2026 – 19:00\nConferenciante:  Francisco González Galindo\nFiliación:  Instituto de Astrofísica de Andalucía (IAA-CSIC) \n  \n
