Interferometric H I intensity mapping: perturbation theory predictions and foreground removal effects
(Oxford University Press, 2023)
We provide perturbation theory predictions for the H I intensity mapping power spectrum multipoles using the Effective Field
Theory of Large Scale Structure, which should allow us to exploit mildly non-linear scales. ...
Constraining primordial non-gaussianity by combining next-generation galaxy and 21 cm intensity mapping surveys
(SpringerOpen, 2023)
Surveys of the matter distribution contain ‘fossil’
information on possible non-Gaussianity that is generated in
the primordialUniverse. This primordial signal survives only
on the largest scales where cosmic variance ...
