Breaking baryon-cosmology degeneracy with the electron density power spectrum
(IOP Publishing, 2022)
Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics
that are robust against these uncertainties, or ...
Finding universal relations in Subhalo properties with artificial intelligence
(The Astrophysical Journal, 2022)
We use a generic formalism designed to search for relations in high-dimensional spaces to determine if the total mass of a subhalo can be predicted from other internal properties such as velocity dispersion, radius, or ...
