Radio and optical connected

Abstract

With instruments of striking diversity and precision, observational cosmologists translate the whispers of distant galaxies into clues to cosmic history. But the same corner of Universe is not often probed with more than one instrument, so we are left to piece together that history like the proverbial blind men examining an elephant. When two probes do intersect, the result is something akin to a Rosetta Stone, where observations at various wavelengths can be woven together to yield a hitherto unseen picture.
