New Infrared Seyfert Galaxies

Q. -S. Gu, J. -H. Huang, H. -J. Su +1

We present optical spectra for new infrared Seyfert galaxies obtained with the 2.16m telescope at Beijing Astronomical Observatory (BAO). After wavelength and flux calibration, the…

An analytic solution of the Boltzmann equation in the presence of self-generated magnetic fields in astrophysical plasmas

L. H. Li

Through relating a self-generated magnetic field to the regular motion of free electrons that is responsible for the magnetic field generation in astrophysical plasmas, we solve th…

Gamma-ray bursts: postburst evolution of fireballs

Y. F. Huang, Z. G. Dai, D. M. Wei +1

The postburst evolution of fireballs that produce -ray bursts is studied, assuming the expansion of fireballs to be adiabatic and relativistic. Numerical results as well as an a…

Is GRO J1744-28 a Strange Star?

K. S. Cheng, Z. G. Dai, D. M. Wei +1

The unusal hard x-ray burster GRO J1744-28 recently discovered by the Compton Gamma-ray Observatory (GRO) can be modeled as a strange star with a dipolar magnetic field $\le 10^{11…

H_2O megamaser emission from FR I radio galaxies

C. Henkel, Y. P. Wang, H. Falcke +2

A systematic search for 22 GHz H2O megamaser emission is reported for 50 nearby (z < 0.15) FR I galaxies. No detection was obtained, implying that ultraluminous H2O masers (L_H2O>1…

Black Hole Energy Release to the Gaseous Universe

Torsten A. Ensslin, Yiping Wang, Biman B. Nath +1

We estimate the energy release of black hole formation to the intra-cluster medium of the Coma cluster and find that this is comparable to the present day energy content. Therefore…

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…
