With the aim of taking full advantage of the complementarity of optical-NIR and sub-millimetre observing facilities, ESO and ALMA have entered into a Joint Proposal agreement, to enable those science cases that require observations with both ALMA and VLT(I) telescopes to have their goals fulfilled.
In this framework, ESO is glad to announce that Joint VLT-ALMA Proposals will be offered as of Period 112 and ALMA Cycle 10, with the formal ESO call to be published at the end of February 2023. By agreement with the ALMA Observatory, ESO may award a maximum of 50 hours of ALMA observing time on each of its arrays to Joint Proposals per year. Similarly, ALMA will be able to allocate up to 50 hours per cycle on the VLT(I) in the yearly ALMA Call for Proposals.
