Detector-frame Cosmology with Non-parametric Methods

Start: 29/05/2024, 14:30 - 15:30
Location: ESAT B91.300 (Aula C)

The challenge of understanding the Universe's dynamics, particularly the Hubble tension, requires precise measurements of the Hubble constant. Building upon the existing spectral siren method, which capitalizes on population information from gravitational wave sources, this talk explores an alternative way to analyse the population data to obtain the cosmological parameters. We'll focus on how non-parametric methods, which are flexible models that can be used to agnostically reconstruct arbitrary probability densities, can be incorporated in this framework and leverage on the detector-frame mass distribution to infer the cosmological parameters
