Keck IR Spectroscopy of WZ Sge: Detection of Molecular Emission from the Accretion Disk
Steve B. Howell, Thomas E. Harrison, Paula Szkody
Time-resolved IR spectroscopy of WZ Sge was obtained using NIRSPEC on Keck II. We detect CO and H emission from the accretion disk placing WZ Sge into a rarefied class of…
A Survey of Open Clusters in the u'g'r'i'z' Filter System: I. Results for NGC2548 (M48)
Cristin J. Rider, Douglas L. Tucker, J. Allyn Smith +3
We present initial results of a photometric survey of open star clusters, primarily in the southern hemisphere, taken in the u'g'r'i'z' filter system. While our entire observed sam…
A Catalog of Compact Groups of Galaxies in the SDSS Commissioning Data
B. C. Lee, S. S. Allam, D. L. Tucker +20
Compact groups (CGs) of galaxies -- relatively poor groups of galaxies in which the typical separations between members is of the order of a galaxy diameter -- offer an exceptional…
Actively Star Forming Elliptical Galaxies at Low Redshifts in the Sloan Digital Sky Survey
Masataka Fukugita, Osamu Nakamura, Edwin L. Turner +2
We report discovery of actively star forming elliptical galaxies in a morphologically classified sample of bright galaxies at a low redshift obtained from the Sloan Digital Sky Sur…
Pion Charge Exchange on Deuterium
J. -P. Dedonder, W. R. Gibbs
We investigate quantum corrections to a classical intranuclear cascade simulation of pion single charge exchange on the deuteron. In order to separate various effects the orders of…
Global structure of the mod two symmetric algebra, H^*(BO;F_2), over the Steenrod Algebra
David J. Pengelley, Frank Williams
The algebra S of symmetric invariants over the field with two elements is an unstable algebra over the Steenrod algebra A, and is isomorphic to the mod two cohomology of BO, the cl…
