A Study on the Chemical Properties of Blue Compact Dwarf Galaxies
Yinghe Zhao, Yu Gao, Qiusheng Gu
In this paper, we report our studies on the gaseous and chemical properties of a relatively large sample (53 members) of blue compact dwarf galaxies (BCDs). The results of correlat…
Hyperbolic Structure and Stickiness Effect: A case of a 2D Area-Preserving Twist Mapping
Li-Yong ZHOU, Jian LI, Jian CHENG +1
The stickiness effect suffered by chaotic orbits diffusing in the phase space of a dynamical system is studied in this paper. Previous works have shown that the hyperbolic structur…
Coupling mechanism between microscopic two-level system and superconducting qubits
Zhen-Tao Zhang, Yang Yu
We propose a scheme to clarify the coupling nature between superconducting Josephson qubits andmicroscopic two-level systems. Although dominant interest in studying two-level syste…
The Carnegie-Irvine Galaxy Survey. III. The Three-Component Structure of Nearby Elliptical Galaxies
Song Huang, Luis C. Ho, Chien Y. Peng +2
Motivated by recent developments in our understanding of the formation and evolution of massive galaxies, we explore the detailed photometric structure of a representative sample o…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Luminosity and Color Dependence and Redshift Evolution
Hong Guo, Idit Zehavi, Zheng Zheng +40
We measure the luminosity and color dependence and the redshift evolution of galaxy clustering in the Sloan Digital Sky Survey-III Baryon Oscillation Spectroscopic Survey Ninth Dat…
Destruction of Lagrangian torus for positive definite Hamiltonian systems
Chong-Qing Cheng, Lin Wang
For an integrable Hamiltonian , we show that any Lagrangian torus with a given unique rotation vector can be destructed by arbitrarily $C^{2d-…
