Explore ultra-light dark matter models and their computational implementation through power spectra emulators in this 41-minute research presentation from the ICTP-SAIFR São Paulo Research Group meetings in Astro & Cosmo. Learn about the theoretical foundations of ultra-light dark matter as an alternative to traditional cold dark matter models, examining how these extremely low-mass particles behave on cosmological scales and influence structure formation. Discover the development and application of power spectra emulators, which are computational tools designed to efficiently predict matter power spectra across different cosmological parameters without running full N-body simulations. Understand the challenges in modeling ultra-light dark matter scenarios and how emulators can accelerate parameter estimation and model comparison in cosmological analyses. Gain insights into current research methodologies for studying alternative dark matter candidates and their observational signatures through large-scale structure measurements.
