| dc.description.abstract | 本研究使用BVR三個寬波段觀測41個近處的活躍星系，本文所進行的研究是針對西佛I,II型星系，及LINERs所處的宿主星系之表面亮度分佈及色指數。41個星系包含5個西佛I型，19個西佛II型，17個LINERs，西佛I型有較藍的核心，宿主星系之顏色並無顯著差異。我們將32個漩渦及棒漩星系的亮度分佈解析成核心、橢球、盤面三個部分，西佛I型星系有較高的核心亮度貢獻，西佛II型其次，LINERs最低；橢球及盤面的部分則未見明顯差異。 | zh_TW |
| dc.description.abstract | We have obtained multi-band (BVR) photometry of a sample of 41 active galaxies, including type 1 Seyfert, type 2 Seyfert galaxies, and low ionization nuclear emission region (LINER). In order to study the physical properties of AGN host galaxies. the intensity pro les in each band are obtained. We calculate the colors of the nuclei and the e ective radii using average B-V, and V-R value. We nd that the Seyfert 1 galaxies have bluer nucleus color. We also caculate the nucleus-to-galaxy ratio, and find that the Seyfert 1 galaxies have higher ratio. | en_US |
