One with HI: Modelling HI Intensity Mapping one-point statistics including systematics
Bernhard Vos-Gines, Cora Uhlemann
Neutral hydrogen (HI) traces the dark matter distribution of the Universe. Upcoming surveys such as the Square Kilometre Array Observatory (SKAO) will trace neutral hydrogen up to…
Cosmology with HI Intensity Mapping
Laura Wolz, Gabriele Autieri, José Luis Bernal +18
The redshifted spectral emission from neutral hydrogen (HI) at rest wavelength 21 cm can be used as a tracer of large-scale structure and its evolution. Within the HI intensity map…
Cosmology with Intensity Mapping via Statistics Beyond the Power Spectrum in the SKAO Era
Suman Majumdar, Debanjan Sarkar, Leon Noble +38
The cosmological distribution of neutral hydrogen (HI) during the post-reionization era is highly non-Gaussian due to the underlying non-linear structure formation, complex galaxy…
Constraining GREA, an alternative theory accounting for the present cosmic acceleration
R. Calderon, J. Garcia-Bellido, B. Vos-Gines +34
The origin of the Universe's late-time accelerated expansion remains unknown. The General Relativistic Entropic Acceleration (GREA) theory offers a compelling alternative to CDM…
