The Recent Stellar Archeology of M31 - The Nearest Red Disk Galaxy
(2012-03-27)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
(2011-04-20)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 ... -
A Redshift Survey of Herschel Far-Infrared Selected Starbursts and Implications for Obscured Star Formation
(2012-12)No abstract available. -
A Redshift Survey of the Submillimeter Galaxy Population
(2005-04)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
(2005-12-20)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
(1973-02/12)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
(2005-09)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
(2004-12-21)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
(2004-11-20)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
(2006-11-10)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
(2005-12-11)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
(APS through AIP, 2003-02/01)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 ... -
