Multipole expansion for HI intensity mapping experiments: simulations and modelling

13 Feb 2020Steven CunningtonAlkistis PourtsidouPaula S. SoaresChris BlakeDavid Bacon

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 formalism. We include simulations of the cosmological HI signal using N-body and log-normal methods, foregrounds and their removal, as well as instrumental effects... (read more)
