Obscured and unobscured active galactic nuclei in the Spitzer Space Telescope First Look Survey
(2004-09)Selection of active galactic nuclei (AGN) in the infrared allows the discovery of AGN whose optical emission is extinguished by dust. In this paper, we use the Spitzer Space Telescope First Look Survey (FLS) to assess what ... -
Observation of a blue shift in the optical response at the fundamental band gap in Ga1-xMnxAs

Observing Cold Gas in Submillimeter Galaxies: Detection of CO(1-0) Emission in SMM J13120+4242 with the Green Bank Telescope
(2006-10-20)We report the first detection of CO(1-0) emission from a submillimeter-selected galaxy, using the Green Bank Telescope. We identify the line in the spectrum of SMM J13120+4242 as a broad emission feature at z=3.408, with ... -
OH, HO2, and NO in two biomass burning plumes: Sources of HOx and implications for ozone production
(1997-12)No abstract available. -
On the accretion origin of a vast extended stellar disk around the Andromeda galaxy
(2005-11-20)We present the discovery of an inhomogenous, low-surface brightness, extended disk-like structure around the Andromeda galaxy (M31) based on a large kinematic survey of more than 2800 stars with the Keck/DEIMOS spectrograph. ... -
On the application of cavity ringdown spectroscopy to measurements of line shapes and continuum absorption

A one-dimensional cloud model with trimodal convective outflow
(American Meteorological Society, 2009)The author describes a one-dimensional cloud model designed to investigate the relationships between stratiform downdrafts, congestus outflow, stability, and relative humidity in the tropical lower troposphere. In the ... -
Optical and Near-Infrared Integral Field Spectroscopy of the SCUBA Galaxy N2-850.4
(2005-05-11)We present optical and near-infrared integral field spectroscopy of the SCUBA galaxy SMM J163650.43+405734.5 (ELAIS N2 850.4) at z=2.385. We combine Ly-alpha and H-alpha emission line maps and velocity structure with high ... -
Optically engineered ultrafast pulses for controlled rotations of exciton qubits in semiconductor quantum dots
(2012-07)No abstract available. -
Optically faint counterparts to the ISO-FIRBACK 170 micron population: the discovery of cold, luminous galaxies at high redshift
(2002-07)We present Keck spectroscopy and UKIRT near-IR imaging observations of two 170micron-selected sources from the ISO-FIRBACK survey which have faint counterparts in the optical, and r-K~5. Both sources were expected to lie ... -
Optimal quantum control for conditional rotation of exciton qubits in semiconductor quantum dots

The origin of [Fe II] emission in NGC 4151
(2002-03)The centre of NGC 4151 has been observed in the J-band with the SMIRFS integral field unit (IFU) on the UK Infrared Telescope. A map of [Fe II] emission is derived, and compared with the distributions of the optical narrow ... -
Origin of lapse rate changes in the upper tropical troposphere
(American Meteorological Society, 2002)Vertical motions in clouds arise from a variety of thermodynamic processes, including latent heat release, evaporative cooling, melting, and cloud radiative heating. In the Tropics, the net upward vertical mass flux from ... -
Ozone and potential vorticity at the subtropical tropopause break

PAndAS in the mist: The stellar and gaseous mass within the halos of M31 and M33
(2012-11-16)Large scale surveys of the prominent members of the Local Group have provided compelling evidence for the hierarchical formation of massive galaxies, revealing a wealth of substructure that is thought to be the debris from ... -
PAndAS' cubs: discovery of two new dwarf galaxies in the surroundings of the Andromeda and Triangulum galaxies
(2009-09-02)We present the discovery of two new dwarf galaxies, Andromeda XXI and Andromeda XXII, located in the surroundings of the Andromeda and Triangulum galaxies (M31 and M33). These discoveries stem from the first year data of ... -
PAndAS' progeny: extending the M31 dwarf galaxy cabal
(2011-02-14)We present the discovery of five new dwarf galaxies, Andromeda XXIII-XXVII, located in the outer halo of M31. These galaxies were found in the second year of data from the Pan-Andromeda Archaeological Survey (PAndAS) of ...
