The Structure of Narrow-Line Region in LINERs

Wang, Ting-Gui; Dai, Hai-Feng

Low-ionization nuclear emission regions (LINERs) are present in a large fraction of local galaxies, while their connection to the more luminous active galactic nuclei (AGN) remains elusive. We analyze the narrow band images obtained by the Hubble Space Telescope (HST) in Hα+[NII] and/or [OIII] band for 23 LINERs and low luminosity Seyfert galaxies…

Circumnuclear Star Forming Activity in NGC 3982

Gu, Qiu-Sheng; Wang, Yi-Peng; Zhang, Shui-Nai

We present a study of the nearby Seyfert galaxy NGC 3982 using optical, infrared and X-ray data acquired by SDSS, Spitzer and Chandra. Our main results are as follows: (1) A simple stellar population synthesis on the nuclear and circumnuclear SDSS spectra gives unambiguous evidence of young stellar components in both the nuclear and circumnuclear …

A Multiwavelength Study of the Jets in FR-I Radio Galaxies: I. Data and Analysis

Zhou, Hong-Yan; Meng, Da-Min

We compile a sample of 11 Fanaroff-Riley type I Radio Galaxies (FR-I RGs) with multi-wavelength observations to address the dynamic behavior of jets in these objects. Optical images acquired by the Hubble Space Telescope (HST) are carefully analyzed. The method and reduction procedure are described in detail. Unresolved optical cores emerge after …
