Tracing the molecular gas in distant submillimetre galaxies via CO(1-0) imaging with the EVLA
(2010-09-03)We report the results of a pilot study with the EVLA of 12CO J=1-0 emission from four SMGs at z=2.2-2.5, each with an existing detection of CO J=3-2. Using the EVLA's most compact configuration we detect strong, broad J=1-0 ... -
Transatlantic transport of pollution and its effects on surface ozone in Europe and North America

A trio of new Local Group galaxies with extreme properties
(2008-12)We report on the discovery of three new dwarf galaxies in the Local Group. These galaxies are found in new CFHT/MegaPrime g,i imaging of the south-western quadrant of M31, extending our extant survey area to include the ... -

Tropospheric aerosol optical thickness from the GOCART model and comparisons with satellite and sun photometer measurements
(American Meteorological Society, 2002)The Georgia Institute of Technology-Goddard Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) model is used to simulate the aerosol optical thickness t for major types of tropospheric aerosols including ... -

Two-component scaling near the metal-insulator bifurcation in two dimensions
(APS through AIP, 2003-05/15)We consider a two-component scaling picture for the resistivity of two-dimensional (2D) weakly disordered interacting electron systems at low temperature with the aim of describing both the vicinity of the bifurcation and ... -
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 ... -

Umklapp electron-electron scattering and the low-temperature electrical resistivity of the alkali metals
(1981-03/15)The Umklapp fraction, , for electron-electron scattering in the alkali metals has been calculated using first-principles pseudopotentials. Both Coulomb scattering and phonon-exchange scattering have been included. For a ... -
Understanding the nature of the optically faint radio sources and their connection to the submillimeter population
(2002-05-10)We present a sample of 43 submillimeter sources detected (at >3 sigma), drawn from our program to follow-up optically faint radio sources with SCUBA. These sources already have associated radio and in many cases optical ...
