Event Horizon Telescope (EHT) 230 GHz Resolution 25 µarcsec
SRT, Medicina, and Noto will be able to observe up to 100 GHz SRT with the VLBI technique, together with the other antennas of 19 GHz the globe. They will be able to reach a resolution that will be Resolution 57 arcsec only two times lower than that of the EHT. Scientific impact expected from the technological enhancement
Project sustainability must be guarantee by INAF for the period 2022 – 2032;
It is estimated that in the ten years following the upgrade, SRT could collect up to 40,000 hours of scientific data;
The astronomical observations with SRT will be made available to the scientific community by means of calls for proposals every six months;
The observations will be assigned on a competitive basis for scientific merit by the Time Allocation Committee (TAC) of experts for the INAF radio telescopes;
