On a Possible Giant Impact Origin for the Colorado Plateau
Xiaolei Zhang
It is proposed and substantiated that an extraterrestrial object of the approximate size and mass of Planet Mars, impacting the Earth in grazing incidence along an approximately N-…
Galaxy Secular Mass Flow Rate Determination Using the Potential-Density Phase Shift Approach: Application to Six Nearby Spiral Galaxies
Xiaolei Zhang, Ronald J. Buta
Using the potential-density phase shift approach developed by the present authors in earlier publications, we estimate the magnitude of radial mass accretion/excretion rates across…
N-Body Simulations of Collective Effects in Spiral and Barred Galaxies
Xiaolei Zhang
We present gravitational N-body simulations of the secular morphological evolution of disk galaxies induced by density wave modes. In particular, we address the demands collective…
Galaxy Secular Mass Flow Rate Determination Using the Potential-Density Phase Shift Approach
Xiaolei Zhang, Ronald J. Buta
We have carried out an initial study of a small sample of nearby spiral and barred galaxies with a broad distribution of Hubble types in order to have a first estimate of the magni…
The Emergence of Consciousness in the Quantum Universe
Xiaolei Zhang
It is argued that human consciousness is likely to have emerged during the self-consistent evolution of the physical universe, through the gradual accumulation of biological entiti…
Density-Wave Induced Morphological Transformation of Galaxies along the Hubble Sequence
Xiaolei Zhang, Ronald J. Buta
In the past two decades, secular evolution has emerged as an important new paradigm for the formation and evolution of the Hubble sequence of galaxies. A new dynamical mechanism wa…
