| Abstract: |
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. |
