Labelling the character tables of symmetric and alternating groups
Mark Wildon
Let be a character table of the symmetric group . It is shown that unless or , there is a unique way to assign partitions of to the rows and columns of $X…
O VI and H_2 Lines in Sunspots
Nicolas Labrosse, Huw Morgan, Shadia Rifai Habbal +1
Sunspots are locations on the Sun where unique atmospheric conditions prevail. In particular, the very low temperatures found above sunspots allow the emission of H_2 lines. In thi…
Spectral Diagnostics of Active Prominences
Nicolas Labrosse, Pierre Gouttebroze, Jean-Claude Vial
Active prominences exhibit plasma motions, resulting in difficulties with the interpretation of spectroscopic observations. These solar features being strongly influenced by the ra…
Spitzer IRAC Images and Sample Spectra of Cassiopeia A's Explosion
J. A. Ennis, L. Rudnick, W. T. Reach +5
We present Spitzer IRAC images, along with representative 5.27 to 38.5 micron IRS spectra of the Cassiopeia A supernova remnant. We find that various IRAC channels are each most se…
Detection of the 205 um [NII] Line from the Carina Nebula
T. E. Oberst, S. C. Parshley, G. J. Stacey +7
We report the first detection of the 205 um 3P1 - 3P0 [NII] line from a ground-based observatory using a direct detection spectrometer. The line was detected from the Carina star f…
On the parameterization dependence of the energy momentum tensor and the metric
N. E. J. Bjerrum-Bohr, John F. Donoghue, Barry R. Holstein
We use results by Kirilin to show that in general relativity the nonleading terms in the energy-momentum tensor of a particle depends on the parameterization of the gravitational f…
