BlueTides Mock Image Catalogue

The BlueTides Mock Image Catalogue is a catalogue of mock images of ~100,000 MUV≃ −22.5 to −19.6 mag galaxies from the BlueTides hydrodynamical simulation at z=7, 8, 9, 10, 11 and 12. This includes mock images of these galaxies with the James Webb, Hubble, Nancy Grace Roman, and Euclid Space Telescopes, as well as Subaru and VISTA, in a range of near- and mid-infrared filters. The catalogue is described in detail Marshall et al. (2022). These images are created from the stellar particle distribution of BlueTides galaxies, as determined through the detailed hydrodynamics of the cosmological simulation. Each star particle in each galaxy is assigned an SED based on its age and metallicity, and nebular continuum, line emission, and dust attenuation are modelled. Fluxes are taken from a convolution of the SEDs with the various filter transmission curves. The images show the 6x6 or 10x10 kpc fields of view surrounding each galaxy, depending on the telescope. The images are binned onto a pixel scale of 0.5 times the native pixel scale of each instrument. These images are convolved with model PSFs, to produce realistic estimates of what true images with these telescopes would look like, although non-convolved images are also available. The catalogue images have no noise, so that they can be adapted for specific use cases. Software for adding noise is available on GitHub, alongside software for accessing and visualising the catalogue data.
