ACME provides transnational access on the basis of scientific merit to a wide range of complementary astroparticle, high-energy and astronomical Research Infrastructures. This will open new opportunities for the science community in the detection, analysis and subsequent follow up of multi-messenger and high-energy time-domain astrophysical events.
The list below reports all the Research Infrastructures offering such transnational access (identified with the tag “TNA”), as well as other telescopes and detectors taking part in other ACME actions.
