The nature of a gravitationally lensed sub-millimetre arc in MS0451.6-0305: two interacting galaxies at z~2.9?
(2004-08-11)We present a new SCUBA image of the cluster MS0451.6-0305, which exhibits strong, extended sub-mm flux at 850 microns. The most striking feature in the map is an elongated region of bright sub-mm emission, with a flux ... -
The nature of the bright submillimeter galaxy population: a radio pre-selected sample with I>25
(2001-2-20)Deep submillimetre surveys have successfully detected distant, star-forming galaxies, enshrouded in vast quantities of dust and which emit most of their energy at far infrared wavelengths. These luminous galaxies are an ... -
Near-IR adaptive optics imaging of nuclear spiral structure in the Seyfert galaxy, NGC3227
(2002-04-04)We present high spatial resolution, near-IR images in J, H, K of the nucleus of NGC3227, obtained with the Adaptive Optics bonnette on CFHT. The ~0.15 arcsec (17pc) resolution allows structures to be probed in the core ... -
Negative electron-electron drag between narrow quantum Hall channels
(APS through AIP, 1998-03/15)Momentum transfer due to Coulomb interaction between two parallel, two-dimensional, narrow, and spatially separated layers, when a current Idrive is driven through one layer, is studied in the presence of a perpendicular ... -
News from the Galactic suburbia: the chemical composition of the remote globular cluster NGC 2419
(2012-08-01)We present the chemical analysis of 49 giant stars of the globular cluster NGC 2419, using medium resolution spectra collected with the multi-object spectrograph DEIMOS@Keck. Previous analysis of this cluster revealed a ... -

Non Axi-symmetric Anisotropy of Solar Wind Turbulence
(2011-8/201)A key prediction of turbulence theories is frame-invariance, and in magnetohydrodynamic (MHD) turbulence, axisymmetry of fluctuations with respect to the background magnetic field. Paradoxically the power in fluctuations ... -

Nonlocal exchange energy of many-fermion systems of arbitrary dimensionality and interparticle interaction
(1986-11/15)The exchange contributions to the ground-state energy of an inhomogeneous many-fermion system of arbitrary dimensionality are calculated. Explicit results are given for both the local-density approximation and the lowest-order ... -

The nucleus of the Sagittarius dSph galaxy and M54: a window on the process of galaxy nucleation
(2008-09-01)We present the results of a thorough study of the nucleus of the Sgr dwarf spheroidal galaxy and of the bright globular cluster M54 that resides within the same nucleus (Sgr,N). We have obtained accurate radial velocities ... -

Obscured and unobscured active galactic nuclei in the Spitzer Space Telescope First Look Survey
(2004-09)Selection of active galactic nuclei (AGN) in the infrared allows the discovery of AGN whose optical emission is extinguished by dust. In this paper, we use the Spitzer Space Telescope First Look Survey (FLS) to assess what ... -

Observing Cold Gas in Submillimeter Galaxies: Detection of CO(1-0) Emission in SMM J13120+4242 with the Green Bank Telescope
(2006-10-20)We report the first detection of CO(1-0) emission from a submillimeter-selected galaxy, using the Green Bank Telescope. We identify the line in the spectrum of SMM J13120+4242 as a broad emission feature at z=3.408, with ...
