Strangeness contribution to the vector and axial form factors of the nucleon
S. F. Pate, G. A. MacLachlan, D. W. McKee +1
The strangeness contribution to the vector and axial form factors of the nucleon is presented for momentum transfers in the range GeV. The results are obtained v…
Stellar Populations in Bulges
Bhasker K. Moorthy, Jon A. Holtzman
We present line strengths in the bulges and inner disks of 38 galaxies in the local universe, including several galaxies whose bulges were previously identified as being disk-like…
Low State, Phase-Resolved IR Spectroscopy of VV Puppis
Steve B. Howell, Thomas E. Harrison, Ryan K. Campbell +2
We present phase-resolved low resolution and higher resolution -band spectroscopy of the polar VV Pup. All observations were obtained when VV Pup was in a low accretion st…
Center vortex model for the infrared sector of SU(4) Yang-Mills theory: String tensions and deconfinement transition
Michael Engelhardt
A random vortex world-surface model for the infrared sector of SU(4) Yang-Mills theory is constructed, focusing on the confinement properties and the behavior at the deconfinement…
Constraining the Projected Radial Distribution of Galactic Satellites with the Sloan Digital Sky Survey
Jacqueline Chen, Andrey V. Kravtsov, Francisco Prada +5
We use the Sloan Digital Sky Survey (SDSS) spectroscopic sample to constrain the projected radial distribution of satellites around isolated ~ L* galaxies. We employ mock galaxy ca…
Constraining the Evolution of the Ionizing Background and the Epoch of Reionization with z ~ 6 Quasars II: A Sample of 19 Quasars
Xiaohui Fan, Michael A. Strauss, Robert H. Becker +7
We study the evolution of the ionization state of the IGM at the end of the reionization epoch using spectra of a sample of nineteen quasars at 5.74<z<6.42 discovered in the SDSS.…
