The stellar halo and outer disk of M33
(2006-08-10)
We present first results from a Keck/DEIMOS spectroscopic survey of red giant branch (RGB) stars in M33. The radial velocity distributions of the stars in our fields are well described by three Gaussian components, ...
A kinematic study of the Andromeda dwarf spheroidal system
(2013-02-26)
We present a homogeneous kinematic analysis of red giant branch stars within 18 of the 28 Andromeda dwarf spheroidal (dSph) galaxies, obtained using the Keck I LRIS and Keck II DEIMOS spectrographs. Based on their g-i ...
A search for the submillimetre counterparts to Lyman break galaxies
(2002-04-04)
We have carried out targetted sub-mm observations as part of a programme to explore the connection between the rest-frame UV and far-IR properties of star-forming galaxies at high redshift, which is currently poorly ...
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) ...
A Keck/DEIMOS Kinematic Study of Andromeda IX: dark matter on the smallest galactic scales
(2005-10-20)
We present the results of a kinematic survey of the dwarf spheroidal satellite of M31, And-IX, which appears to be the lowest surface brightness and also the faintest galaxy (M_V = -8.3) found to date. Using Keck/DEIMOS ...
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 ...
PAndAS in the mist: The stellar and gaseous mass within the halos of M31 and M33
(2012-11-16)
Large scale surveys of the prominent members of the Local Group have provided compelling evidence for the hierarchical formation of massive galaxies, revealing a wealth of substructure that is thought to be the debris from ...
Modeling the evolution of infrared luminous galaxies: the influence of the Luminosity-Temperature distribution
(2005-03)
The evolution of the luminous infrared galaxy population is explored using a pure luminosity evolution model which incorporates the locally observed luminosity-temperature distribution for IRAS galaxies. Pure luminosity ...
