Proposals are invited for observations with the APEX telescope in the observing period April–July 2022 (APEX). Deadline: Friday 22 October 2021 (23:59:59 UTC).

APEX is a 12 m diameter submillimetre telescope at 5100 m altitude on Llano Chajnantor in Chile. The receivers offered in this Call are the heterodyne receivers SEPIA (SEPIA180: 159-211 GHz; SEPIA345: 272-376 GHz; SEPIA660: 578-738 GHz) and nFLASH (nFLASH230: 200-270 GHz; nFLASH460: 385-500 GHz), and the bolometer arrays ArTeMiS (350 and 450 μm) and CONCERTO (with a Martin-Puplett interferometer for a spectral resolution of >1.5 GHz in the 130-310 GHz range).

Observations on Swedish time on APEX are supported by the ORP Transnational Access programme.
