Description
Over the past decade, there has been a move to better connect observations with
numerical simulations. In this work we focus on mimicking the CO emission for
simulated Giant Molecular Clouds (GMCs). We performed a set of smooth particle
hydrodynamics (SPH) simulations with time-dependent chemistry, in which environmental
conditions such as mass, density, size, metallicity and Interstellar Radiation Field
were systematically varied. The simulations were then post-processed using radiative
transfer (via RADMC-3D) to create synthetic integrated emission maps. Synthetic
emission maps are created for different lines of CO’s rotational ladder as well as
different CO isotopes. We show how various CO lines trace different regions in the
GMCs. For example comparing the ratio between CO’s first two rotational emission
lines allows the differentiation between regions of different temperatures and
densities, as shown in the following figure.
