Description
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 SARAO Square Kilometer Array (SKA) site in South Africa. Through 21cm Intensity Mapping, HIRAX will provide a cosmological survey of the distribution of the large-scale structure over the redshift range of $ 0.775 < z < 2.55$ over ~$15,000$ square degrees of the southern sky. I shall talk about parameter estimation for the Dark Energy EOS parameters, $w_0$ and $w_a$, particularly using an end-to-end simulation pipeline based on m-mode formalism for matter power spectrum estimation.
