The globular cluster NGC 2419: a crucible for theories of gravity
(2011-06-24)
We present the analysis of a kinematic data set of stars in the globular cluster NGC 2419, taken with Keck/DEIMOS. Combined with a reanalysis of deep HST and Subaru imaging data, which provide an accurate luminosity profile ...
The LABOCA Survey of the Extended Chandra Deep Field South: Clustering of submillimetre galaxies
(2011-12-01)
We present a measurement of the spatial clustering of submillimetre galaxies (SMGs) at z = 1-3. Using data from the 870 micron LESS survey, we employ a novel technique to measure the cross-correlation between SMGs and ...
The large-scale structure of the halo of the Andromeda Galaxy Part I: global stellar density, morphology and metallicity properties
(2013-11-22)
We present an analysis of the large-scale structure of the halo of the Andromeda galaxy, based on the Pan-Andromeda Archeological Survey (PAndAS), currently the most complete map of resolved stellar populations in any ...
The LABOCA survey of the Extended Chandra Deep Field South: Two modes of star formation in AGN hosts?
(2010-01-30)
We study the co-existence of star formation and AGN activity in X-ray selected AGN by analyzing stacked 870um submm emission from a deep and wide map of the Extended Chandra Deep Field South, obtained with LABOCA at the ...
The Hubble Space Telescope GOODS NICMOS Survey: Overview and the Evolution of Massive Galaxies at 1.5 < z < 3
(2010-10-06)
We present the details and early results from a deep near-infrared survey utilising the NICMOS instrument on the Hubble Space Telescope centred around massive M_* > 10^11 M_0 galaxies at 1.7 10^11 M_0, whereby we find an ...
Large gas reservoirs and free-free emission in two lensed star-forming galaxies at z=2.7
(2013-05-02)
We report the detection of CO(1-0) line emission in the bright, lensed star-forming galaxies SPT-S 233227-5358.5 (z=2.73) and SPT-S 053816-5030.8 (z=2.78), using the Australia Telescope Compact Array (ATCA). Both galaxies ...
The scatter about the "Universal" dwarf spheroidal mass profile: A kinematic study of the M31 satellites, And V and And VI
(2011-03-10)
While the satellites of the Milky Way (MW) have been shown to be largely consistent in terms of their mass contained within one half--light radius (M_{half}) with a "Universal" mass profile, a number of M31 satellites are ...
HerMES: Clusters of Dusty Galaxies Uncovered by Herschel and Planck
(2014)
The potential for Planck to detect clusters of dusty, star-forming galaxies at z greater than 1 is tested by examining the Herschel-SPIRE images of Planck Early Release Compact Source Catalog (ERCSC) sources lying in fields ...
The Star Formation History and Dust Content in the Far Outer Disc of M31
(2011-11-22)
We present a detailed analysis of two fields located 26 kpc (~5 scalelengths) from the centre of M31. One field samples the major axis populations--the Outer Disc field--while the other is offset by ~18' and samples the ...
The AGN fraction of submm-selected galaxies and contributions to the submm/mm-wave extragalactic background light
(2010-02-18)
We present a comparison of the SCUBA Half Degree Extragalactic Survey (SHADES) at 450, 850 and 1100 microns with deep guaranteed time 15 microns AKARI FU-HYU survey data and Spitzer guaranteed time data at 3.6-24 microns ...
