Pattern Speeds and Galaxy Morphology
R. Buta, X. Zhang
The morphology of a disk galaxy is closely linked to its kinematic state. This is because density wave features are likely made of spontaneously-formed modes which are allowed to a…
The optical spectral slope variability of 17 blazars
Shao Ming Hu, G. Zhao, H. Y. Guo +2
Many quasi-simultaneous optical observations of 17 blazars are obtained from previous papers published over the last 19 years in order to investigate the spectral slope variability…
HII regions in spiral galaxies: Size distribution, luminosity function, and new isochrone diagnostics of density wave kinematics
M. S. Oey, J. S. Parker, V. J. Mikles +1
We investigate the relationship of the HII region luminosity function (HII LF) to the HII region size distribution and density wave triggering in grand-design spiral galaxies. We s…
The infrared and optical variability of OJ 287
J. H. Fan, G. Adam, G. Z. Xie +7
In this paper, the long-term historical optical (UBVRI) and near-infrared (JHK) data are presented with some new observations in the optical (February 1994-January 1995) and near-i…
