HI intensity mapping with MeerKAT: Calibration pipeline for multi-dish autocorrelation observations
Jingying Wang, Mario G. Santos, Philip Bull +10
While most purpose-built 21cm intensity mapping experiments are close-packed interferometer arrays, general-purpose dish arrays should also be capable of measuring the cosmological…
Power spectrum multipole expansion for HI intensity mapping experiments: unbiased parameter estimation
Paula S. Soares, Steven Cunnington, Alkistis Pourtsidou +1
We assess the performance of the multipole expansion formalism in the case of single-dish HI intensity mapping, including instrumental and foreground removal effects. This formalis…
The cosmic abundance of cold gas in the local Universe
Thomas J. Fletcher, Amelie Saintonge, Paula S. Soares +1
We determine the cosmic abundance of molecular hydrogen (H2) in the local universe from the xCOLD GASS survey. To constrain the H2 mass function at low masses and correct for the e…
Multipole expansion for HI intensity mapping experiments: simulations and modelling
Steven Cunnington, Alkistis Pourtsidou, Paula S. Soares +2
We present a framework and an open-source python toolkit to analyse the 2-point statistics of 3D fluctuations in the context of HI intensity maps using the multipole expansion form…
