Preliminary Exploration of Areal Density of Angular Momentum for Spiral Galaxies.

Abstract (from CDS):

The specific angular momenta (jt) of stars, baryons as a whole and dark matter halos contain clues of vital importance about how galaxies form and evolve. Using a sample of 70 spiral galaxies, we perform a preliminary analysis of jt, and introduce a new quantity, e.g., areal density of angular momentum (ADAM) (${j}_{t}\,{M}_{\star }/{(2{R}_{d})}^{2}$) as an indication for the existence of jet(s) in spiral galaxies. The percentage of spiral galaxies having jet(s) shows a strong correlation with ADAM, although the present sample is incomplete.
