Deep Gemini/GMOS imaging of an extremely isolated globular cluster in the Local Group
We report on deep imaging of a remote M31 globular cluster, MGC1, obtained with Gemini/GMOS. Our colour-magnitude diagram for this object extends ~5 magnitudes below the tip of the red giant branch and exhibits features ... -
Deep observations of CO line emission from star-forming galaxies in a cluster candidate at z=1.5
We report results from a deep Jansky Very Large Array (JVLA) search for CO 1-0 line emission from galaxies in a candidate galaxy cluster at z~1.55 in the COSMOS field. We target 4 galaxies with optical spectroscopic redshifts ... -
Deep SAURON Spectral-Imaging of the diffuse Lyman-alpha halo LAB1 in SSA22
We have used the SAURON panoramic integral field spectrograph to study the structure of the Ly-alpha emission-line halo, LAB1, surrounding the sub-millimeter galaxy SMM J221726+0013. This emission-line halo was discovered ... -
A Deep WSRT 1.4 GHz Radio Survey of the Spitzer Space Telescope FLSv Region
The First Look Survey (FLS) is the first scientific product to emerge from the Spitzer Space Telescope. A small region of this field (the verification strip) has been imaged very deeply, permitting the detection of ... -
Density dependence of critical magnetic fields at the metal-insulator bifurcation in two dimensions
The density dependence of the critical in-plane magnetic field Bc at the bifurcation of the resistivity of two-dimensional electron systems with low levels of disorder is determined using the spin-polarization dependence ... -

Density Variations in the NW Star Stream of M31
The Pan Andromeda Archeological Survey (PAndAS) CFHT Megaprime survey of the M31-M33 system has found a star stream which extends about 120 kpc NW from the center of M31. The great length of the stream, and the likelihood ... -
Depth-dependent static shielding of an impurity by a quantum plasma in a magnetic field
The static shielding of a charged impurity embedded in a quantum plasma is studied with the use of linear-response theory. The required response function is calculated in the random-phase approximation with a uniform ... -

Detection of a Fermi level crossing in three-domain Si(111)-In(4x1)
Using photoemission and inverse photoemission, it has recently been demonstrated that single domain Si(111)-In(4 X 1) overlayers possess a clear Fermi level crossing at approximate to 0.6 azimuth of the 1 x I zone, which ... -
Detection of molecular gas in a distant submillimetre galaxy at z=4.76 with ATCA
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 ... -
Diamagnetic susceptibility of a dense electron gas
The authors calculate the diamagnetic susceptibility of a uniform interacting electron gas in the random-phase approximation. From this the exact high-density expansion of the diamagnetic susceptibility is obtained -

Diffusion of Asymmetric Swimmers
Asymmetric swimmers that would move at a constant speed in perfect circles in the absence of fluctuations were studied. Particles moving at a constant speed with either a fixed or a Gaussian distributed magnitude of curvature ... -
Dipole-dipole interactions and the critical resistivity of gadolinium
Results are presented for the electrical resistivity of a c-axis single crystal of high-purity gadolinium metal in the immediate vicinity of the Curie temperature. Numerical analysis reveals that the data are not well ... -
