if you could use any astronomical instrument you haven't used before which one would you choose?
eizher arecibo (if i'm allowed to want non-operational ones) or zhe atacama cosmology telescope
i do work wizh archival arecibo data but i would have loved zhe chance to actually gazher data wizh it
and if i'm using atacama it means i'm probably gazhering polarization data of zhe CMB which is one of my ideal projects
