Description

The EAGLE cosmological simulations reproduce the observed galaxy stellar mass function and many galaxy properties to unprecedented levels of agreement. In this work, we study the dust-related properties of present-day EAGLE galaxies through mock observations in the far-infrared and submm wavelength range obtained with the 3D dust radiative transfer code SKIRT. Specifically, we select a set of redshift-zero EAGLE galaxies that matches the K-band luminosity distribution of the galaxies in the Herschel Reference Survey (HRS), a volume-limited sample of about 300 normal galaxies in the Local Universe. We find overall agreement of the EAGLE dust scaling relations with those observed in the HRS, and we investigate the effect of adjusting certain assumptions in our post-processing procedure. As a result, we are able to constrain the important dust-related parameters in our method, informing the calculation of dust attenuation for EAGLE galaxies in the UV and optical domain.
