摘要(中) 我對悉尼澳大利亞天文台（SAMI）星系巡天中的空間分辨運動學剖面進行了調查，涵蓋了 SAMI 第三輪釋出的數據中八個星系團的多目標積分視場光譜儀測量數據。我的分析集中在成員橢圓星系的一維運動學分佈，透過 IFS 檢查其內在的星系屬性。在我的初步研究中，我辨識了八個星系團中的 12 個最亮星系團星系，並將 127 個橢圓星系的速度彌散分佈分類為四個不同的組別：平坦型、下降型、上升型和不規則型。結合總恆星質量，透過 Jeans 方程式和 Hernquist 模型估算每個星系的視線速度彌散分佈。一個顯著的觀察是，許多最亮星系團星系（BCGs）主要表現出平坦的速度彌散分佈。此外，許多橢圓星系則具有下降的分佈vi 摘要(英) I conducted an investigation of spatially resolved kinematic profiles within the Sydney-Australian-Astronomical-Observatory (SAMI) galaxy survey, encompassing Multi-object Integral-Field Spectrograph measurements across eight galaxy clusters in the SAMI Date Released 3. My analysis focused on the one-dimensional kinematic profiles of member elliptical galaxies, examining their intrinsic galactic properties through IFS. In my preliminary study, I identified the 12 biggest cluster galaxies within eight clusters and categorized the velocity dispersion profiles of 127 elliptical galaxies into four distinct groups: flat, declining, ascending, and irregular (or unclassified). With the total stellar mass, the line-of-sight velocity dispersion profile of each galaxy is estimated by the Jean equation with Hernquist model. A notable observation was that many brightest cluster galaxies predominantly exhibited flat velocity dispersion profiles. Also, many elliptical galaxies have declining profiles. 關鍵字(中) ★ 星系團
