A Redshift Survey of the Submillimeter Galaxy Population
We have obtained spectroscopic redshifts using the Keck-I telescope for a sample of 73 submillimeter (submm) galaxies for which precise positions are available. The galaxies lie at redshifts out to z=3.6, with a median ... -

The Relationship Between Stellar and Black-Hole Mass in Submillimeter Galaxies
We analyze deep X-ray, optical and mid-infrared Spitzer observations of the CDF-N/GOODS-N region to study 13 submillimeter-detected galaxies (SMGs) with spectroscopic redshifts (median z=2.2). We find a correlation between ... -
Resistive anomalies at the critical point of isotropic ferromagnets
The effect of spin fluctuations on electrical resistivity (T) is studied in a single-band model. It is shown that d(T)/dT varies as the magnetic specific heat for TTc as well as TTc and that both short-range and long-range ... -

Rest-frame optical and far-infrared observations of extremely bright Lyman-break galaxy candidates at z ~ 2.5
We have investigated the rest-frame optical and far-infrared properties of a sample of extremely bright candidate Lyman-break galaxies (LBG) identified in the Sloan Digital Sky Survey. Their high ultraviolet luminosities ... -
The Rest-Frame Optical Properties of SCUBA Galaxies
We present optical and near-IR photometry of 96 dusty, far-IR luminous galaxies. We have precise spectroscopic redshifts for all these galaxies yielding a median redshift of z=2.2. The majority, 78, are submm-detected ... -
The Rest-frame Optical Spectra of SCUBA Galaxies
We present near-infrared spectroscopy and narrow-band imaging at the wavelength of redshifted H-alpha for a sample of 30 high-redshift, far-infrared luminous galaxies. This sample is selected from surveys in the sub-millimeter, ... -
Restframe Optical Spectroscopic Classifications for Submillimeter Galaxies
We report the results of a systematic near-infrared spectroscopic survey using the Subaru, VLT and Keck Telescopes of a sample of high redshift Ultra-luminous Infrared Galaxies (ULIRGs) mainly composed of submillimeter-selected ... -
A robust sample of submillimetre galaxies: constraints on the prevalence of dusty, high-redshift starbursts
The modest significance of most sources detected in current submm surveys can potentially compromise some analyses due to the inclusion of spurious sources in catalogues typically selected at >3.0-3.5sigma. Here, we develop ... -
Role of interfaces in the magnetoresistance of Au/Fe/Au/Fe multilayers
By using the fully relativistic spin-polarized screened Korringa-Kohn-Rostoker method and the corresponding Kubo-Greenwood equation resistivities and the giant magnetoresistance are evaluated for Fe/Au/Fe/Au spin valves ... -

The scatter about the "Universal" dwarf spheroidal mass profile: A kinematic study of the M31 satellites, And V and And VI
While the satellites of the Milky Way (MW) have been shown to be largely consistent in terms of their mass contained within one half--light radius (M_{half}) with a "Universal" mass profile, a number of M31 satellites are ...
