Dish Assembly Precision for HIRAX
Jennifer Studer, Devin Crichton, Alexandre Refregier +16
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array that is being deployed at the South African Radio Astronomy Observatory (SARAO) Squ…
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 from HI galaxy surveys with the SKA
Ainulnabilah Nasirudin, Philip Bull, Ziad Sakr +8
The 21cm line from neutral hydrogen is expected to be a ubiquitous (albeit faint) tracer of galaxies in the late Universe. With SKAO-MID, large wide-field surveys of several millio…
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…
Exploring Beyond ΛCDM with the Weak Lensing Power Spectrum and Bispectrum
Liantsoa F. Randrianjanahary, Chandrachud B. V. Dash
In this work, we present Fisher matrix forecast of the tomographic weak lensing power spectrum and bispectrum for three physically distinct types of models of beyond-CDM: the CP…
Cosmological constraints from the EFT power spectrum and tree-level bispectrum of 21cm intensity maps
Liantsoa F. Randrianjanahary, Dionysios Karagiannis, Roy Maartens
We explore the information content of 21cm intensity maps in redshift space using the 1-loop Effective Field Theory power spectrum model and the bispectrum at tree level. The 21cm…
Cosmological constraints from the power spectrum and bispectrum of 21cm intensity maps
Dionysios Karagiannis, Roy Maartens, Liantsoa Randrianjanahary
The 21cm emission of neutral hydrogen is a potential probe of the matter distribution in the Universe after reionisation. Cosmological surveys of this line intensity will be conduc…
The Hydrogen Intensity and Real-time Analysis eXperiment: 256-Element Array Status and Overview
Devin Crichton, Moumita Aich, Adam Amara +97
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the S…
