Line Strengths

Line strengths and their gradients in Mg, Fe, and Hβ have been determined for a sample of 20 S0 galaxies in order to study the stellar populations of their bulges and disks and to investigate their relationship to elliptical galaxies. The data were obtained with the Lick Observatory 3m telescope in the long-slit mode over the region 4215–5615 Å with resolution 3.1 Å.

Line Strengths

Attention is drawn to the fact that perturbing terms to the HAMILTONian of the asymmetric rigid rotor molecule which are linear in the operators of angular momentum components may be evaluated to second order in the asymmetric rotor basis with the help of published line strengths tables. The usefulness is demonstrated by means of an example where the hindering potential for the internal rotation of the two methyl groups in acetone is calculated from a certain splitting in the quartet torsional fine structure of rotational absorption lines.

AbstractWe present very deep HST/ACS images of five QSO host galaxies, classified as undisturbed ellipticals in earlier studies. For four of the five objects, our images reveal strong signs of interaction such as tidal tails, shells, and other fine structure, suggesting that a large fraction of QSO host galaxies may have experienced a relatively recent merger event. Our preliminary results for a control sample of inactive elliptical galaxies do not reveal comparable fine structure.
