Cluster cosmology is potentially one of the most powerful observational probes of structure formation. However, enabling unbiased cosmological constraints requires careful modeling of the cluster selection function. In the case of optical cluster cosmology, this requires accurate modeling of projection effects. We will introduce a new simulation-based inference framework with which we reanalyze DES Y1 […]

Dark Matter Clues from the Faintest Galaxies

Speaker: Julio Navarro Institution: University of Victoria Abstract: Lambda Cold Dark Matter (LCDM) is the most successful theory for the formation of structure in the Universe. Although its predictions have been verified on large scales, they are still contested on the scale of dwarf galaxies, whose dynamical properties are often cited as evidence for the […]

Holographic thermal entropy and modular conjugation from geodesic bit threads

Clubs científicos

Speaker: Francesco Gentile Institution: SISSA Location&Place: Grey Room 2 Abstract: In this talk, I will discuss some new interesting properties of geodesic bit threads in static backgrounds. Bit threads are an insightful tool for investigating holographic entanglement entropy, providing a reformulation of the Ryu-Takayanagi formula in terms of the maximal flux of a bounded and […]

Exploring infinite distance limits of type II Calabi–Yau compactifications

Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain
Eventos científicos

Speaker: Luca Melotti Institution:  IFT UAM/CSIC Location&Place: Blue Room Abstract: This thesis explores infinite distance limits in the vector multiplet moduli space of type II string theory on Calabi–Yau threefolds. First we classify such limits, identify the towers of light states, and test the Emergence Proposal, which links IR kinetic terms to loop corrections from […]

On the Asymptotic Global Structure of Duality Frames in Quantum Gravity

Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain
Eventos científicos

Speaker: Ignacio Ruiz García Institution: IFT UAM/CSIC Location&Place: Blue Room Abstract: This thesis studies the global asymptotic structure of moduli spaces in effective field theories compatible with Quantum Gravity, focusing on the Swampland Distance Conjecture. We develop taxonomy rules that determine the arrangement of towers of light states and duality frames at infinite distance, showing a […]

Will we know the Neutrino Mass Ordering by the end of 2026?

Eventos científicos

The JUNO reactor neutrino experiment has recently begun collecting data, marking the start of a new precision era in neutrino research. With its unparalleled precision, JUNO is poised to refine our understanding of most neutrino oscillation parameters. Its cornerstone measurement - the determination of the neutrino mass ordering -- holds the promise of a breakthrough. […]
