A trio of new Local Group galaxies with extreme properties
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
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
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
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
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
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 ... -
Unearthing Foundations of a Cosmic Cathedral: Searching the Stars for M33's Halo
We use data from the Pan-Andromeda Archaeological Survey (PAndAS) to search for evidence of an extended halo component belonging to M33 (the Triangulum Galaxy). We identify a population of red giant branch (RGB) stars at ... -
Universal correction to scaling amplitude ratios for inhomogeneous ferromagnets with continuous symmetry
Critical exponents and amplitude ratios for corrections to the scaling limit are calculated for a randomly diluted, weakly inhomogeneous O(m) Heisenberg model in an expansion in =4-d. Calculations for the exponents and ...
