The ARTEMIS project focuses on the formation of Milky Way-type galaxies. The main question we are trying to answer is how did our Galaxy, the Milky Way, form and evolve? Specifically, we want to know what was its merger history and how did the past mergers affect its evolution. More broadly, we want to understand how unique was this formation history in the cosmological context. We therefore compare our sample of simulated galaxies with many other 'Milky Way analogues' observed in the Universe.
The ARTEMIS suite consists of 45 Milky Way-mass galaxies simulated in a Lambda CDM universe at high resolution. The simulations were run with a version of the TreePM-SPH code Gadget-3 with galaxy formation physics developed for the EAGLE simulations, a flagship Virgo Consortium project.

In the Camps et al (2022) paper we present redshift zero synthetic dust-aware observations for the 45 Milky Way-mass simulated galaxies of the ARTEMIS project, calculated with the SKIRT radiative transfer code. The post-processing procedure includes components for star-forming regions, stellar sources, and diffuse dust. We produce and publicly release realistic high-resolution images for 50 commonly used broadband filters from ultraviolet to sub-millimetre wavelengths and for 18 different viewing angles. Links to these images can be found below.
