SUMMARY:The Experiment for Cryogenic Large-aperture Intensity Mapping
(EXCLAIM)\, Astronomy Colloquium\, Eric Switzer\, NASA/Goddard
DESCRIPTION:The EXperiment for Cryogenic Large-Aperture Intensity Mapp
ing (EXCLAIM) is a cryogenic balloon-borne instrument that will survey
galaxy and star formation history over cosmological time scales. Rath
er than identifying individual objects\, EXCLAIM will be a pathfinder
to demonstrate an intensity mapping approach\, which measures the cumu
lative redshifted line emission. EXCLAIM will operate at 420-540 GHz w
ith a spectral resolution R=512 to measure the integrated CO and [CII]
in redshift windows spanning 0 < z < 3.5. CO and [CII] line emissions
are key tracers of the gas phases in the interstellar medium involved
in star-formation processes. EXCLAIM will shed light on questions suc
h as why the star formation rate declines at z < 2\, despite continued
clustering of the dark matter. The instrument will employ an array of
six superconducting integrated grating-analog spectrometers (micro-sp
ec) coupled to microwave kinetic inductance detectors (MKIDs). I will
present an overview of the EXCLAIM instrument design and status.
