I am a summer intern working on images of simulated galaxies, comparing them with actual galaxies. I was wondering how to download Illustris simulation images from the website efficiently, and if they are available in .jpeg format. I don't want the whole set of images though, only a few hundred.
Also, if possible, are there images which are wrong results? This would help me test my data better.
I'd suggest you download the SKIRT Synthetic Images and Optical Morphologies for the TNG100-1 simulation at z=0.
If you follow the link to the actual data downloads for TNG100-1, at the bottom you'll see a link to the "entire dataset as one file (20-40 GB each per snapshot/survey combination)", and get this for snapshot 99, probably SDSS.
You can look inside and see the assortment of images and take it from there.
Thanks for the suggestion. Is there a way to not download the whole set. I am a little short on memory and don't really want a lot of data.
Yes, you can follow the details of the documentation and download the images for individual galaxies, i.e. selecting some in a reasonable mass range.
