Polytropic model fits to the globular cluster NGC 2419 in Modified Newtonian Dynamics
We present an analysis of the globular cluster NGC 2419, using a polytropic model in Modified Newtonian Dynamics (MOND) to reproduce recently published high quality data of the structure and kinematics of the system. We ... -
A population of hot, dusty ultra-luminous galaxies at z~2
We report spectroscopic redshifts for 18 microJy-radio galaxies at mean redshift of z=2.2 that are faint at both submmillimeter (submm) and optical wavelengths. While the radio fluxes of these galaxies could indicate ... -

The Properties of Microjansky Radio Sources in the HDF-N, SSA13, and SSA22 Fields
(abridged) We present multiwavelength observations for a large sample of microjansky radio sources detected in ultradeep 1.4GHz maps centered on the Hubble Deep Field-North (HDF-N) and the Hawaii Survey Fields SSA13 and ... -
The Properties of Sub-mm Galaxies in Hierarchical Models
We use the combined GALFORM semi-analytical model of galaxy formation and GRASIL spectrophotometric code to investigate the properties of galaxies selected via their sub-mm emission. Our fiducial model has previously been ... -
Pulling helices inside bacteria: imperfect helices and rings
We study steady-state configurations of intrinsically-straight elastic filaments constrained within rod-shaped bacteria that have applied forces distributed along their length. Perfect steady-state helices result from axial ... -
Quantification of the factors controlling tropical tropospheric ozone and the South Atlantic maximum

Quantum critical behavior in the insulating region of the two-dimensional metal-insulator transition
We show that the quantum critical point associated with the metal-insulator transition phenomenon in two dimensions controls an extended critical region encompassing not only the usual quantum critical sector but also a ... -

Quantum dynamics of pseudospin solitons in double-layer quantum wall systems (vol 83, pg 1411, 1999)

Radio galaxy selected clusters at high redshift and associated ERO overdensities
Galaxy clusters at high redshift present a superb opportunity to study galaxy evolution, with large galaxy samples at fixed distances. Several lines of evidence point towards large formation redshifts and passive evolution ... -
Radio imaging of the Subaru/XMM-Newton Deep Field - III. Evolution of the radio luminosity function beyond z=1
We present spectroscopic and eleven-band photometric redshifts for galaxies in the 100-uJy Subaru/XMM-Newton Deep Field radio source sample. We find good agreement between our redshift distribution and that predicted by ... -

The Recent Stellar Archeology of M31 - The Nearest Red Disk Galaxy
We examine the star-forming history (SFH) of the M31 disk during the past few hundred Myr. The luminosity functions (LFs) of main sequence stars at distances R_GC > 21 kpc (i.e. > 4 disk scale lengths) are matched by models ... -
Redshift Determination and CO Line Excitation Modeling for the Multiply-Lensed Galaxy HLSW-01
We report on the redshift measurement and CO line excitation of HERMES J105751.1+573027 (HLSW-01), a strongly lensed submillimeter galaxy discovered in Herschel/SPIRE observations as part of the Herschel Multi-tiered ...
