Description
Brown dwarfs with thick water cloud atmospheres, ancient population III brown dwarfs, and nearby free-floating planetary mass objects are targets in our new discovery space. We have developed a candidate selection process that identifies near infrared sources without optical counterparts whose infrared/optical fluxes are not consistent with stars, and whose infrared colors are not like those of known L and T dwarf populations. We plan to carry out this programme over the next 3-4 years, and effectively give UKIDSS and VISTA the capability to measure proper motions of unusual objects in 14000 sq degs of infrared sky. High proper motion discoveries will be fast-tracked for spectroscopy through our ongoing 8m class telescopes initiatives.
