We have performed a statistical study of the properties of the broadband continuum of Narrow Line Seyfert 1 galaxies (NL......
盘星系的内禀扁度对计算星系的空间倾角非常重要.对从LEDA数据库中选取的14988个盘星系进行内禀扁度的统计分析.研究表明,盘星系的......
The sizes of the Broad Line Region (BLR) of some Seyfert 1 galax-ies and nearby quasars can be determined by the reverbe......
We use controlled N-body simulation to investigate the dynamical processes (dynamical friction, tidal truncation, etc.) ......

We introduce a new code for cosmological simulations, PHoToNs, which incorporates fea-tures for performing massive cosmo......
A first new luminosity function of galaxies can be built starting from a left truncated beta probability density functio......
Magnetic field can be amplified and twisted near a supermassive black hole residing in a galactic nucleus. At the same t......
A multiwavelength study of a nearby dust lane early-type galaxy IC 5063 is presented. The objectives are to investigate ......
We analyse the possibility that the observed cosmological redshift may be cumulatively due to the expansion of the unive......
Discovery of six high-redshift quasars with the Lijiang 2.4 m telescope and the Multiple Mirror Tele
Quasars with redshifts greater than 4 are rare, and can be used to probe the structure and evolution of the early univer......
We present a multi-transition study to investigate the physical properties of dust and moleculargas in the archetypical ......
We present the results of the Chandra high-resolution observation of the Seyfert 2 galaxy NGC 7590. This object was repo......
Missing Mass and Galactic Dust with a Size Greater than 200 Microns, Minimum Size of the Micrometric
The studies of the glaciologists show that, since 30,000 years, the Earth receives every year approximately 40,000 tons ......
