Contribution of water vapor dimers to clear sky absorption of solar radiation
Using previously derived-values of the water vapor dimer spectral absorption cross section we calculate the water vapor dimer contribution to the clear sky absorption of solar radiation. We consider the water dimer ... -
Convergence properties as a function of spatial dimensionality of gradient expansions for the ground-state energy of an inhomogeneous electron gas
The extended Thomas-Fermi approximation for the ground-state energy of a many-fermion system is generalized to arbitrary spatial dimension. The authors' objective is a better understanding of convergence properties of such ... -
Critical behavior of two-dimensional magnetic systems with dipole-dipole interactions
The critical exponents of two-dimensional dipolar magnetic systems with isotropic in-plane ordering may be obtained from the expansion which determines the exponents of isotropic three-dimensional dipolar systems. However, ... -
Critical exponents and amplitude ratios from electrical resistivity measurements of dysprosium
Resistive anomalies in helical antiferromagnets are shown to reflect the temperature dependence of the specific heat sufficiently close to the Neel temperature. The temperature dependence of superzone energy gaps does not ... -

Critical magnetic susceptibility of gadolinium
The magnetic suspectibility of a single crystal of high-purity gadolinium has been measured in the critical region with use of AC susceptibility methods. For reduced temperatures t10-3, the data are described by a simple ... -

Dark channels in resonant tunneling transport through artificial atoms
We investigate sequential tunneling through a multilevel quantum dot confining multiple electrons in the regime where several channels are available for transport within the bias window. By analyzing solutions to the master ... -

Deep Gemini/GMOS imaging of an extremely isolated globular cluster in the Local Group
We report on deep imaging of a remote M31 globular cluster, MGC1, obtained with Gemini/GMOS. Our colour-magnitude diagram for this object extends ~5 magnitudes below the tip of the red giant branch and exhibits features ... -
Deep observations of CO line emission from star-forming galaxies in a cluster candidate at z=1.5
We report results from a deep Jansky Very Large Array (JVLA) search for CO 1-0 line emission from galaxies in a candidate galaxy cluster at z~1.55 in the COSMOS field. We target 4 galaxies with optical spectroscopic redshifts ... -
Deep SAURON Spectral-Imaging of the diffuse Lyman-alpha halo LAB1 in SSA22
We have used the SAURON panoramic integral field spectrograph to study the structure of the Ly-alpha emission-line halo, LAB1, surrounding the sub-millimeter galaxy SMM J221726+0013. This emission-line halo was discovered ... -
A Deep WSRT 1.4 GHz Radio Survey of the Spitzer Space Telescope FLSv Region
The First Look Survey (FLS) is the first scientific product to emerge from the Spitzer Space Telescope. A small region of this field (the verification strip) has been imaged very deeply, permitting the detection of ... -
Density dependence of critical magnetic fields at the metal-insulator bifurcation in two dimensions
The density dependence of the critical in-plane magnetic field Bc at the bifurcation of the resistivity of two-dimensional electron systems with low levels of disorder is determined using the spin-polarization dependence ... -

Density Variations in the NW Star Stream of M31
The Pan Andromeda Archeological Survey (PAndAS) CFHT Megaprime survey of the M31-M33 system has found a star stream which extends about 120 kpc NW from the center of M31. The great length of the stream, and the likelihood ...
