Here’s what I think Geckzilla might mean by “mystical and arcane words”, with one exception:
Rachel, Matthew & Stacy wrote:We present optical long-slit and SparsePak Integral Field Unit emission line spectroscopy along with optical broadband and near-IR images of the edge-on spiral galaxy NGC 2683. We find a multi-valued, figure-of-eight velocity structure in the inner 45'' of the long-slit spectrum and twisted isovelocity contours in the velocity field. We also find, regardless of wavelength, that the galaxy isophotes are boxy. We argue that taken together, these kinematic and photometric features are evidence for the presence of a bar in NGC 2683. We use our data to constrain the orientation and strength of the bar.
Yes, I would say that that abstract is quite, well, abstract. Except for the word “boxy” which is quite understandable.
My apologies to Kuzio de Naray et al, the authors of
Kinematic and Photometric Evidence for a Bar in NGC 2683.
