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…

Recovery of 21 cm BAO: a configuration-space correlation function analysis

Zhongyue Zhang, Kwan Chuen Chan, Santiago Avila +1

Intensity mapping (IM) represents an innovative and potent probe to cosmology. One of its prime applications is to measure the Baryonic Acoustic Oscillations (BAO) in the late univ…

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…

Improving and extending non-Poissonian distributions for satellite galaxies sampling in HOD: applications to eBOSS ELGs

Bernhard Vos-Ginés, Santiago Avila, Violeta Gonzalez-Perez +1

Halo Occupation Distribution (HOD) models help us to connect observations and theory, by assigning galaxies to dark matter haloes. In this work we study one of the components of HO…

HI intensity mapping correlation function from UNIT simulations: BAO and observationally induced anisotropy

Santiago Avila, Bernhard Vos-Ginés, Steven Cunnington +4

We study the clustering of HI intensity maps produced from simulations with a focus on baryonic acoustic oscillations (BAO) and the effects induced by telescope beam smoothing and…
