Some catastrophic photo-z failures in template fitting but these are reduced with ML. Also tested on a COSMOS-like reference sample. Lots of multi-wavelength data for EDF from MeerKAT/LOFAR(2.0) to VISTA,HSC,Spitzer can help with deblending - could use GANs?

For most of the 15000 deg' of the EWS, photo-¡s recovery will be optimal for cosmology. Things are more of a mixed bag for stellar masses and SFRs; to a certain degree, we can confide in recovered stellar masses, not SFRs, at least for the whole catalog of detected sources. Better confidence could be put in bright sources whose photo- is almost perfectly recovered (or with spec-z available), but even in the most ideal scenario, those nine photometric bands yield at least 8% catastrophic outliers in SFR. For the EDE, the recovered SFRs still look worrisome, but the fields will undoubtedly rely on a wealth of ancillary or forthcoming multiwavelength observations in those domains where we can obtain better constraints (i.e., sub-mm, radio) Deblending to Euclid resolution has to be done. Within ELSA, we want to test the performance of super-resolution GANs to achieve this task, at least at the Proof of Concept level. Improvements to the EWS - outlier analysis

Giulia Caldoni, Data Steward in the Research Services Division in Bologna, now briefing us on the open science requirements and our Data Management Plan deliverable. Publication embargos are no longer allowed in Horizon. Peer-reviewed papers on arXiv are ok; APCs not funded in Horizon. A&A OA is ok.
