Hello, I would like to study power spectra (let's say for z=0, ideally also for e.g. z=1 and z=2) from TNG300-1 simulations (from DMO and hydro, not only for total matter but also for other species, such as gas or total baryons, CDM). I could not find such products anywhere online, would it be possible to get them anyhow? Many thanks in advance for your help.

Unfortunately there aren't any catalogs or pre-computed files generally available.
If you don't require very large dynamic range, then any number of available packages should exist and work without much trouble (just googling for "cosmology power spectra library" or similar).

You could use the Gadget-4 functionality.
Many thanks, this is useful. I will have a look.
