SUMMARY:10th IBS/IFT workshop: Dark World to the Swampland
DESCRIPTION:The IBS-IFT Workshop is a regular event organized jointly by IFT and IBS-CTPU\, this year reaching its tenth anniversary. \nThe aim of the workshop is share ideas\, foster collaborations\, and to discuss recent developments in theoretical physics. \nThe event is organized over two weeks. The first week\, November 4-7\, will focus on String Phenomenology  \nThe Center for Theoretical Physics of the Universe is one of the 30 centers of the Institute of Basic Science in South Korea. The IBS-CTPU carries out research on particle physics and cosmology\, which aims to understand nature at the most fundamental level and answer the big questions about the origin of the universe. \nThe Institute for Theoretical Physics IFT UAM-CSIC is a joint research center belonging to the Spanish National Research Council (CSIC) and the Universidad Autónoma de Madrid (UAM). It is the only Spanish center dedicated entirely to research in Theoretical Physics. The IFT members develop research in the frontiers of Elementary Particle Physics\, Astroparticles\, and Cosmology\, in order to understand the fundamental keys of Nature and the Universe. \nWith this workshop we want to try to advance our understanding of quantum gravity\, mainly through the swampland program\, by refining several of the conjectures that have been put forth in the program to bridge the gap between effective field theories and the UV completion as quantum gravity.

SUMMARY:Machine Learning Journal Club: 'Hierarchical Simulation-Based Inference of Supernova Physics'
DESCRIPTION:Speaker: Alex Gagliano (IAIFI/MIT) \nVenue&Time: 11:00 / Grey Room 2 \nAbsrtact: Supernovae are powered by diverse physical mechanisms such as radioactive decay\, circumstellar interaction\, and magnetar spin-down\, but distinguishing among them from light curves alone remains a major challenge. In this talk\, I’ll present a hierarchical simulation-based inference framework that jointly infers both the dominant power source and the key physical parameters of supernovae. By training conditional neural density estimators end-to-end across multiple physical models\, this approach yields calibrated posteriors even in regions of strong degeneracy. I’ll highlight the model’s performance on synthetic data and outline plans to fine-tune the model for population-level studies of diverse explosion physics.

SUMMARY:DIFT Colloquium: 'String Theory and the Dark Sector'
DESCRIPTION:Speaker: Cumrun Vafa (Harvard)\n\n\n\n\n\nVenue & Time: Aula Polivalente\, Plaza Mayor UAM / 15:30 \nAbstract: The dark sector — comprising dark energy and dark matter — has remained a profound mystery for decades. In this talk\, I will review this subject and show how string theory naturally leads to a predictive framework for a unified dark sector. I will also discuss how these string-theoretic predictions align with exciting recent cosmological observations from the DES and DESI collaborations. \n\n\nThis seminar is related to the I+D+i project whose reference is CEX2020-001007-S\, funded by MCIN/AEI/10.13039/501100011033. The topic is framed within the following research lines: \n\nOrigin and composition of the universe: Astroparticles and Cosmology (Astro/Cosmo)\nStrings and quantum gravity (Gravity/Strings)
