We present the discovery of seven ultracool brown dwarfs identified with the Wide-field Infrared Survey Explorer (WISE). Near-infrared spectroscopy reveals deep absorption bands of H_(2)O and CH_4 that indicate all seven of the brown dwarfs have spectral types later than UGPS J072227.51–054031.2, the latest-type T dwarf currently known. The spectrum of WISEP J182831.08+265037.8 is distinct in that the heights of the J- and H-band peaks are approximately equal in units of f λ, so we identify it… Expand
THE FIRST HUNDRED BROWN DWARFS DISCOVERED BY THE WIDE-FIELD INFRARED SURVEY EXPLORER (WISE)

A STUDY OF THE DIVERSE T DWARF POPULATION REVEALED BY WISE
TLDR
The substantial increase in the number of known late-type T dwarfs provides a population that will be used to test models of cold atmospheres and star formation and supports the possible re-emergence of clouds after the L/T transition. Expand
