3D Supernova (Remnants). How to connect simulations and observations?

Supernova (SN) are among the most fascinating events occurring in the universe. Recent years have brought tremendous progress in observations of young remnants of these explosions that show a genuinely three dimensional structure of the ejected matter. New instruments like JWST or Athena will increase our knowledge further. At the same time our theoretical understanding allows us to model SN consistently from the explosion up to the first centuries in full 3D and first qualitative comparisons are performed. New numerical tools are becoming available to study also 3D effects on the lightcurve or spectra of SN explosions. Therefore, it is now timely to connect the observations to theory in a quantitative way. For this purpose, the models need to be improved and appropriate measures or metrics need to be found to quantify differences between observations and different models.
