Black hole to bulge mass correlation in Active Galactic Nuclei: A test for the simple unified formation scheme

Y. P. Wang, P. L. Biermann, A. Wandel

A mass correlation of central black holes and their spheroids ~0.002(within a factor of three) is suggested by Hubble Space Telescope (HST) and various ground-based CCD photometrie…

A series representation of the nonlinear equation for axisymmetrical fluid membrane shape

B. Hu, Q. H. Liu, J. X. Liu +3

Whatever the fluid lipid vesicle is modeled as the spontaneous-curvature, bilayer-coupling, or the area-difference elasticity, and no matter whether a pulling axial force applied a…

The nucleon spin structure in a simple quark model

Bo-Qiang Ma, Ivan Schmidt, Jian-Jun Yang

We investigate the spin structure of the nucleon in an extended Jaffe-Lipkin quark model. In addition to the conventional structure, different admixtures in t…

Effects of galaxy mergers on the faint IRAS source counts and the background

Yiping Wang, Peter L. Biermann

Binary merging constitutes a complementary mode of galaxy evolution to the canonical hierarchical clustering theory. This merger-driven evolution not only influences the galaxy mas…

A possible mechanism for the mass ratio limitation in early type galaxies

Yiping Wang, Peter L. Biermann

There is an interesting correlation between the central objects and their host galaxies in recent high resolution HST photometry of early type galaxies and Near-IR images of nearby…
