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 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 ...
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 Herschel Multi-Tiered Extragalactic Survey: SPIRE-mm Photometric Redshifts
(2011-09-13)
We investigate the potential of submm-mm and submm-mm-radio photometric redshifts using a sample of mm-selected sources as seen at 250, 350 and 500 {\mu}m by the SPIRE instrument on Herschel. From a sample of 63 previously ...
PAndAS' progeny: extending the M31 dwarf galaxy cabal
(2011-02-14)
We present the discovery of five new dwarf galaxies, Andromeda XXIII-XXVII, located in the outer halo of M31. These galaxies were found in the second year of data from the Pan-Andromeda Archaeological Survey (PAndAS) of ...
A joint analysis of BLAST 250--500um and LABOCA 870um observations in the Extended Chandra Deep Field South
(2011-02-11)
We present a joint analysis of the overlapping BLAST 250, 350, 500um, and LABOCA 870um observations (from the LESS survey) of the ECDF-S. Out to z~3, the BLAST filters sample near the peak wavelength of far-infrared (FIR) ...
Ultra Steep Spectrum radio sources in the Lockman Hole: SERVS identifications and redshift distribution at the faintest radio fluxes
(2011-08-19)
Ultra Steep Spectrum (USS) radio sources have been successfully used to select powerful radio sources at high redshifts (z>~2). Typically restricted to large-sky surveys and relatively bright radio flux densities, it has ...
Constraining Dust and Molecular Gas Properties in Lyman Alpha Blobs at z 3
(2011-10-07)
In order to constrain the bolometric luminosities, dust properties and molecular gas content of giant Lyman alpha nebulae, the so-called Lyman alpha blobs, we have carried out a study of dust continuum and CO line emission ...
Polytropic model fits to the globular cluster NGC 2419 in Modified Newtonian Dynamics
(2011-10-18)
We present an analysis of the globular cluster NGC 2419, using a polytropic model in Modified Newtonian Dynamics (MOND) to reproduce recently published high quality data of the structure and kinematics of the system. We ...
