Abstract
AbstractWe presentSimSpin, a new, public, software framework for generating integral field spectroscopy (IFS) data cubes fromN-body/hydrodynamical simulations of galaxies, which can be compared directly with observational datasets.SimSpinprovides a consistent method for studying a galaxy’s stellar component. It can be used to explore how observationally inferred measurements of kinematics, such as the spin parameter$\lambda_R$, are impacted by the effects of, for example, inclination, seeing conditions, distance.SimSpinis written in R and has been designed to be highly modular, flexible, and extensible. It is already being used by the astrophysics community to generate IFS-like cubes and FITS files for direct comparison of simulations to observations. In this paper, we explain the conceptual framework ofSimSpin; how it is implemented in R; and we demonstrateSimSpin’s current capabilities, providing as an example a brief investigation of how numerical resolution affects how reliably we can recover the intrinsic stellar kinematics of a simulated galaxy.
