Today Alexandre Beelen is observing the COSMOS field remotely from his office at Marseille, both with CONCERTO at APEX and with NIKA2 on the IRAM 30m telescope. With CONCERTO, this observation is part of our [CII] intensity-mapping survey. With NIKA2, we are observing COSMOS as part of the N2CLS (NIKA2 Cosmological Legacy Survey) Large Program.
