| dc.description.abstract | 本研究是使用泛星計畫(Panoramic Survey Telescope & Rapid Response System，簡稱Pan-STARRS)的y波段觀測來探討合併星系的性質。這些合併星系是來自於合併星系目錄，該目錄是由Hwang & Chang (2009) 所製作的，他們使用了紅序列星系團巡天二號計畫(Red-sequence Cluster Survey 2)所拍攝的影像找出了約莫一萬五千個合併星系，而我們將對這一萬多個合併星系進行測光的流程。我們使用由Huang & Hwang (2014) 所研發的不規則天體孔徑測光方法對這些合併星系做測光，得到初步的測光結果，接著使用史隆數位巡天計畫(SDSS)來做校正，進而得到準確的測光結果。我們使用校正過的測光資料去計算合併星系的恆星質量，得到這些合併星系的恆星質量約莫是介在1010到1012個太陽質量之間，因此我們更新了合併星系目錄，並且紀錄合併星系在y波段下的結果。 | zh_TW |
| dc.description.abstract | We study the y′?band images of merging galaxies from the observations of the Panoramic Survey Telescope & Rapid Response System (Pan-STARRS). The merging systems were selected from the merging catalog of Hwang & Chang (2009),
which were identified by checking the images of the Red-sequence Cluster Survey 2from the observations of the Canada France Hawaii Telescope (CFHT). By using a
homomorphic-aperture method developed by Huang & Hwang (2014), we determine the photometric results of these merging systems. To obtain results with accurate photometry, we calibrated the r′?, z′?,and y′?band data to match the results of the SDSS DR9. We used the calibrated y′?band data to investigate the stellar mass of merging galaxies. Our results show that the stellar mass of merging galaxies are about 10^10 to 10^12M⊙. We also created a new catalog to record the y′?band results of the merging galaxies. | en_US |
