The K-band properties of Seyfert 2 galaxies
ZhiXin Peng, Qiusheng Gu, Jorge Melnick +1
It is well known that the [O {\sc iii}]5007 emission line and hard X-ray(2-10keV) luminosities are good indicators of AGN activities and that the near and mid-infrared emission…
The Circumnuclear Star-forming Activities along the Hubble Sequence
Lei Shi, Qiusheng Gu, Zhixin Peng
In order to study the circumnuclear star-forming activity along the Hubble sequence, we cross-correlate the Sloan Digital Sky Survey Data Release 2 (SDSS DR2) with the Third Refere…
IC 225: a dwarf elliptical galaxy with a peculiar blue core
Qiusheng Gu, Yinghe Zhao, Lei Shi +2
We present the discovery of a peculiar blue core in the elliptical galaxy IC 225 by using images and spectrum from the Sloan Digital Sky Survey (SDSS). The outer parts of the surfa…
Elliptical Galaxies with Emission Lines from the Sloan Digital Sky Survey
Ying-He Zhao, Qiu-Sheng Gu, Zhi-Xin Peng +3
We present the results of 11 elliptical galaxies with strong nebular emission lines during our study of star formation history along the Hubble sequence. After removing the dilutio…
