The dramatic size evolution of elliptical galaxies and the quasar feedback
L. Fan, A. Lapi, G. De Zotti +1
Observations have evidenced that passively evolving massive galaxies at high redshift are much more compact than local galaxies with the same stellar mass. We argue that the observ…
The Correlation between X-ray and UV Properties of BAL QSOs
LuLu Fan, HuiYuan Wang, Tinggui Wang +4
We compile a large sample of broad absorption lines (BAL) quasars with X-ray observations from the \xmm archive data and Sloan Digital Sky Survey Data Release 5. The sample consist…
SDSS J160531.84+174826.1: A Dwarf Disk Galaxy With An Intermediate-Mass Black Hole
Xiaobo Dong, Tinggui Wang, Weimin Yuan +7
We report the discovery of a dwarf Seyfert 1 active galactic nucleus (AGN) with a candidate intermediate-mass black hole hosted by the dwarf galaxy SDSS J160531.84+174826.1 at z=0.…
Investigating on the nuclear obscuration in two types of Seyfert 2 galaxies
X. W. Shu, J. X. Wang, P. Jiang +2
We build a large sample of Seyfert 2 galaxies (Sy2s) with both optical spectropolarimetric and X-ray data available, in which 29 Sy2s with the detection of polarized broad emission…
