This type of astronomy commonly uses arrays of indium antimonide or mercury cadmium telluride as detectors and uses "chopping and nodding" to cut down on background. The J-H-K-K-prime filter set is commonly used in this field. One experiment in this type of astronomy discovered a type of starburst galaxy with luminosity greater than 10 to the 11th L and which are commonly home to hydroxyl megamasers. Paolo Maffei pioneered this type of astronomy, and used it to find the Maffei 1 and 2 galaxies in the Zone of Avoidance. The 2MASS experiment surveyed the sky using the techniques in this field. Background in this type of astronomy often comes from telluric lines, (*) galactic cirrus and the zodiacal light. The IRAS (EYE-ras) satellite was the first to completely image the sky using this technique, which was also the subject of the Spitzer telescope. The sub-millimeter range is a subset of the "far" side of the range studied in this field, which is the range at which most galactic dust glows. This field got its start when William Herschel discovered calorific rays from the sun. For 10 points, name this type of astronomy which studies wavelength ranges between microwave and visible.
