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 ... -

An upper limit to [C II] emission in a z ~= 5 galaxy
Low-ionization-state far-infrared (FIR) emission lines may be useful diagnostics of star-formation activity in young galaxies, and at high redshift may be detectable from the ground. In practice, however, very little is ... -
Using [CI] to probe the Interstellar Medium in z~2.5 Sub-Millimeter Galaxies
We present new [CI](1-0) and 12CO(4-3) Plateau de Bure Interferometer observations of five Sub-Millimeter Galaxies (SMGs) and combine these with all available [CI](1-0) literature detections in SMGs to probe the gas ... -
Using SCUBA to place upper limits on arcsecond scale CMB anisotropies at 850 microns
The SCUBA instrument on the James Clerk Maxwell Telescope has already had an impact on cosmology by detecting relatively large numbers of dusty galaxies at high redshift. Apart from identifying well-detected sources, such ... -

The vertical structure of tropical convection and its impact on the budgets of water vapor and ozone
Convective clouds in the Tropics that penetrate the boundary layer inversion preferentially detrain into a shallow outflow layer (2-5 km) or a deep outflow layer (10-17 km). The properties of these layers are diagnosed ... -
A Vigorous Starburst in the SCUBA Galaxy N2 850.4
We present optical and near-IR spectroscopy of a z=2.38 hyperluminous IR galaxy, covering the restframe wavelength range from 1000-5000A. It appears to comprise two components separated by less than 1" on the sky (<8kpc); ... -
