UKIRT Infrared Deep Sky SurveyUKIRT Infrared Deep Sky SurveyScience Goals:
• find the nearest and faintest sub-stellar objects
• break the z=7 quasar barrier
• determine the epoch of re-ionisation
• determine the substellar mass function
• discover Pop II brown dwarfs, if they exist
• construct a galaxy catalogue at z=1 as large as the SDSS catalogue
• measure the growth of structure and bias from z=3 to the present day
• determine the epoch of spheroid formation
• clarify the relationship between quasars, ULIRGs, and galaxy formation
• map the Milky Way through the dust, to several kpc
• increase the number of known Young Stellar Objects by an order of magnitude, including rare types such as FU Orionis stars

UKIRT’s Long-Term FutureUKIRT’s Long-Term Future
Two directions being developed:
• extended and enhanced wide-field imaging hemisphere-scale survey potentially with polarimetry potentially with 4k arrays
• planet detection Earth-mass planets in habitable zones around parent stars M dwarfs extension of radial velocity technique into infrared

UKIRT Planet Finder (UPF)
• high-stability, high-resolution echelle spectrograph in YJH
• wide range of astrophysical applications besides planet hunting
• 3yr to build it, cost c.£5M
• 5yr to do the science, 50% of the telescope time
• letter of intent endorsed by STFC
• full proposal now in preparation: decision by end 2009
• led by Hugh Jones (Herts)
