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.

The UKIDSS project is defined in Lawrence et al. (2007). UKIDSS uses the UKIRT Wide Field Camera (WFCAM; Casali et al. 2007) and a photometric system described in Hewett et al. (2006). The pipeline processing and science archive are described in Irwin et al. (in preparation) and Hambly et al. (2008). We have used data from the eightth data release. Funding for the SDSS and SDSS-II has been provided by the Alfred P Sloan Foundation, the Participating Institutions, the National Science Foundation, the U.S. Department of Energy, the National Aeronautics and Space Administration, the Japanese Monbukagakusho, the Max Planck Society, and the Higher Education Funding Council for England. The SDSS Web Site is http://www.sdss.org/. The Southern Astrophysical Research (SOAR) Telescope is a 4.1 meter aperture telescope designed to work from the atmospheric cut-off in the blue (320 nm) to the near infrared, to have excellent image quality (0.22 arcseconds), fast slewing and to have up to nine instruments mounted ready for use. It was funded by a a partnership between the U.S. National Optical Astronomy Observatory (NOAO), the Ministrio da Ciencia e Tecnologia of the Federal Republic of Brazil (MCT), the University of North Carolina at Chapel Hill (UNC), and Michigan State University (MSU). ZengHua Zhang is supported by the University of Hertfordshire Research Studentship. Avril Day-Jones is founded supported by the Fondecyt Fellowship (No. 3100098), Maria Teresa Ruiz has received support from FONDAP (CONICYT) and proyecto BASAL (CATA). James Jenkins is supported by the Fondecyt grant (No. 3110004).
