The Global Schmidt law in star forming galaxies
Measurements of Hα, H I, and CO distributions in 61 normal spiral galaxies are combined with published far-infrared and CO observations of 36 infrared-selected starburst galaxies, in order to studyExpand

The Milky Way Tomography with SDSS. I. Stellar Number Density Distribution
Using the photometric parallax method we estimate the distances to ~48 million stars detected by the Sloan Digital Sky Survey (SDSS) and map their three-dimensional number density distribution in theExpand

Evolution since Z = 0.5 of the morphology-density relation for clusters of galaxies
Using traditional morphological classifications of galaxies in 10 intermediate-redshift (z similar to 0.5) clusters observed with WFPC2 on the Hubble Space Telescope, we derive relations betweenExpand

Direct Oxygen Abundances for Low Luminosity LVL Galaxies
We present MMT spectroscopic observations of H II regions in 42 low luminosity galaxies in the Spitzer Local Volume Legacy survey. For 31 of the 42 galaxies in our sample, we were able to measure theExpand

Optical Star Formation Rate Indicators
Using integrated optical spectrophotometry for 412 star-forming galaxies at z ~ 0, and fiber-aperture spectrophotometry for 120,846 SDSS galaxies at z ~ 0.1, we investigate the Hα λ6563, Hβ λ4861, [OExpand

Multivalued logic gates for quantum computation
We develop a multi-valued logic for quantum computing for use in multi-level quantum systems, and discuss the practical advantages of this approach for scaling up a quantum computer. Generalizing theExpand

The Infrared Spectra of Very Large, Compact, Highly Symmetric, Polycyclic Aromatic Hydrocarbons (PAHs)
The mid-infrared spectra of large PAHs ranging from C54H18 to C130H28 are determined computationally using density functional theory. Trends in the band positions and intensities as a function of PAHExpand

The Sloan Digital Sky Survey monitor telescope pipeline
The photometric calibration of the Sloan Digital Sky Survey (SDSS) is a multi-step process which involves data from three different telescopes: the 1.0-m telescope at the US Naval Observatory (USNO),Expand
