We present a scattering mitigation framework for radio imaging with very long baseline interferometry (VLBI) that partially overcomes this limitation.

For expected values of the inner scale, the scattering kernel for all models is markedly non-Gaussian at 1. 3 mm but is straightforward to calculate and depends only weakly on the assumed model for the wandering of the magnetic field direction.

We perform quantitative measurements of relevant polarimetric properties of the compact emission and find evidence for the temporal evolution of the polarized source structure over one week of EHT observations.

These studies are important when proposing observations of new sources, in the characterization of the capabilities of new or upgraded instruments, and when verifying model-based theoretical predictions in a comparison with observational data.

Supermassive black holes at the centre of active galactic nuclei power some of the most luminous objects in the Universe.

Our long-baseline detections to ALMA also provide new constraints on the scattering of Sgr A*, and we show that refractive scattering effects are likely to be weak for images of Sgr A* at 1. 3 mm with the Event Horizon Telescope.

This stage allowed us to avoid shared human bias and to assess common features among independent reconstructions.
