Evidence for an accretion origin for the outer halo globular cluster system of M31
(2010-05-20)
We use a sample of newly-discovered globular clusters from the Pan-Andromeda Archaeological Survey (PAndAS) in combination with previously-catalogued objects to map the spatial distribution of globular clusters in the M31 ...
Detection of molecular gas in a distant submillimetre galaxy at z=4.76 with ATCA
(2010-04-22)
We have detected the CO(2-1) transition from the submillimetre galaxy (SMG) LESSJ033229.4-275619 at z=4.755 using the new Compact Array Broadband Backend system on the Australian Telescope Compact Array. These data have ...
A Hubble Space Telescope NICMOS and ACS Morphological Study of z~2 Submillimetre Galaxies
(2010-02-12)
We present a quantitative morphological analysis using HST NICMOS H160- and ACS I775- band imaging of 25 spectroscopically confirmed submillimetre galaxies (SMGs) which have redshifts between z=0.7-3.4. Our analysis also ...
