Disentangling the Dynamical Mechanisms for Cluster Galaxy Evolution
Xiaolei Zhang
The determination of the dynamical causes of the morphological Butcher-Oemler (BO) effect, or the rapid transformation of a large population of late-type galaxies to earlier Hubble…
Secular Evolution and the Morphological Transformation of Cluster and Field Galaxies
Xiaolei Zhang, Ronald J. Buta
Deep surveys conducted during the past decades have shown that galaxies in the distant universe are generally of more irregular shapes, and are disky in appearance and in their sta…
The Potential-Density Phase Shift Method for Determining the Corotation Radii in Spiral and Barred Galaxies
Xiaolei Zhang, Ronald J. Buta
We have developed a new method for determining the corotation radii of density waves in disk galaxies, which makes use of the radial distribution of an azimuthal phase shift betwee…
Large Scale CO and [CI] emission in the rho Ophiuchi Molecular Cloud
Craig A. Kulesa, Aimee L. Hungerford, Christopher K. Walker +2
We present a comprehensive study of the rho Ophiuchi molecular cloud that addresses aspects of the physical structure and condition of the molecular cloud and its photodissociation…
Galaxy Scaling Relations as a Result of Secular Evolution
Xiaolei Zhang
The secular evolution process which slowly transforms the morphology of a given galaxy over its lifetime through mostly internal dynamical mechanisms could naturally account for mo…
Secular Evolution of Disks
Xiaolei Zhang
It is found that a previously thought-to-be well established result of density wave theory, that there is no interaction between a quasi-stationary spiral density wave and the basi…
