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…
21cm foregrounds and polarization leakage: a user's guide on cleaning and mitigation strategies
Steven Cunnington, Melis O. Irfan, Isabella P. Carucci +2
The success of HI intensity mapping is largely dependent on how well 21cm foreground contamination can be controlled. In order to progress our understanding further, we present a r…
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 degeneracy between primordial non-Gaussianity and foregrounds in 21cm intensity mapping experiments
Steven Cunnington, Stefano Camera, Alkistis Pourtsidou
Potential evidence for primordial non-Gaussianity (PNG) is expected to lie in the largest scales mapped by cosmological surveys. Forthcoming 21cm intensity mapping experiments will…
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…
