Fourth-order gradient contributions in extended Thomas-Fermi theory for noninteracting fermions at finite temperature
Nonlocal corrections to the free energy of a system of noninteracting fermions are considered within the framework of extended Thomas-Fermi theory. The density and temperature dependence of gradient corrections is given ... -
A Fully-Identified Sample of AEGIS20 Microjansky Radio Sources
Infrared 3.6 to 8 micron images of the Extended Groth Strip yield plausible counterpart identifications for all but one of 510 radio sources in the AEGIS20 S(1.4 GHz) > 50 micro-Jy sample. This is the first such deep sample ... -

Further multiwavelength observations of the SSA22 Ly_alpha emitting `blob'
We present new follow-up observations of the sub-mm luminous Ly_alpha-emitting object in the SSA22 z=3.09 galaxy overdensity, referred to as `Blob 1' by Steidel et al.(2000). In particular we discuss high resolution Hubble ... -
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS). I: The UV luminosity function of the central 12 sq.deg
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) is a complete blind survey of the Virgo cluster covering about 40 sq. deg. in the far UV (FUV, lambda_eff=1539A, Delta-lambda=442A) and about 120 sq. deg. in the near UV ... -

The globular cluster NGC 2419: a crucible for theories of gravity
We present the analysis of a kinematic data set of stars in the globular cluster NGC 2419, taken with Keck/DEIMOS. Combined with a reanalysis of deep HST and Subaru imaging data, which provide an accurate luminosity profile ... -
Gradient corrections in the exchange and correlation energy of an inhomogeneous electron gas
A closed form expression for the coefficient Bxc which determines the first gradient corrections to the exchange and correction energy is derived. The exact expression is obtained from an approximation that includes the ... -
The Haunted Halos of Andromeda and Triangulum: A panorama of galaxy formation in action
We present a deep photometric survey of M31, conducted with the CFHT and INT, covering the inner 50 kpc of the galaxy, the Southern quadrant out to 150 kpc, and extending to M33. This is the first systematic panoramic study ... -
The HDF-North SCUBA Super-map I: Submillimetre maps, sources and number counts
We investigate the emission of sub-millimetre-wave radiation from galaxies in a 165 square arcminute region surrounding the Hubble Deep Field North. The data were obtained from dedicated observing runs from our group and ... -
The HDF-North SCUBA Super-map II: Multi-wavelength properties
We present radio, optical and X-ray detected counterparts to the sub-mm sources found using SCUBA in the Hubble Deep Field North region (GOODS-N). A new counterpart identification statistic is developed to identify properties ... -
Heat capacity of gadolinium near the Curie temperature
High-resolution AC calorimetric data near the Curie point are reported for several single crystals of gadolinium. The critical temperature and the shape of the heat-capacity curve near Tc both depend on the sample-preparation ... -
Helical magnetic order in MnSi thin films
We present a study of the magnetic structure of crystalline MnSi(111) thin films grown by molecular beam epitaxy. A combination of polarized neutron reflectometry (PNR) and superconducting quantum interference device ... -
HerMES: Candidate Gravitationally Lensed Galaxies and Lensing Statistics at Submillimeter Wavelengths
We present a list of 13 candidate gravitationally lensed submillimeter galaxies (SMGs) from 95 square degrees of the Herschel Multi-tiered Extragalactic Survey, a surface density of 0.14\pm0.04deg^{-2}. The selected sources ... -
HerMES: Candidate High-Redshift Galaxies Discovered with Herschel/SPIRE
We present a method for selecting $z>4$ dusty, star forming galaxies (DSFGs) using Herschel/SPIRE 250/350/500 $\mu m$ flux densities to search for red sources. We apply this method to 21 deg$^2$ of data from the HerMES ...
