Abstract

Far-infrared (far-IR) astronomical observations with sub-arcsecond angular resolution and high spectral resolution require a space-based interferometer observatory with baselines of at least tens of meters in length. The European-funded Far Infrared Space Interferometer Critical Assessment (FISICA) studied Far Infrared Interferometer (FIRI) in detail, and developed software simulation tools (FIInS and PyFIInS) for modeling a FIRI-like interferometer and simulating the hyperspectral output datacubes. Here we present on-going work expanding upon the foundations of FIInS and pyFIInS towards an end-to-end simulation software suite. The software tools presented in this work provide a framework with which to study double Fourier interferometry in the far-IR and allow the astronomical community further exploration of the unique capabilities of such instrumentation.
