Charging and Growth of Fractal Dust Grains
Lorin S. Matthews, Truell W. Hyde
The structure and evolution of aggregate grains formed within a plasma environment are dependent upon the charge acquired by the micron-sized dust grains during the coagulation pro…
Dark energy and cosmic curvature: Monte-Carlo Markov Chain approach
Yungui Gong, Qiang Wu, Anzhong Wang
We use the Monte-Carlo Markov Chain method to explore the dark energy property and the cosmic curvature by fitting two popular dark energy parameterizations to the observational da…
Current constraints on interacting holographic dark energy
Qiang Wu, Yungui Gong, Anzhong Wang +1
Although there is mounting observational evidence that the cosmic expansion is undergoing a late-time acceleration, the physical mechanism behind such a phenomenon is yet unknown.…
Energy conditions and current acceleration of the universe
Yungui Gong, Anzhong Wang
The energy conditions provide a very promising model-independent study of the current acceleration of the universe. However, in order to connect these conditions with observations,…
Direct evidence of acceleration from distance modulus redshift graph
Yungui Gong, Anzhong Wang, Qiang Wu +1
The energy conditions give upper bounds on the luminosity distance. We apply these upper bounds to the 192 essence supernova Ia data to show that the Universe had experienced accel…
Formation of Cosmic Dust Bunnies
Lorin S. Matthews, Ryan L. Hayes, Michael S. Freed +1
Planetary formation is an efficient process now thought to take place on a relatively short astronomical time scale. Recent observations have shown that the dust surrounding a prot…
