Abstract
Çalışmamızın amacı, galaksi kümelerinin merkezinde yer alan ve evrendeki en parlak ve en büyük kütleli galaksiler olan merkezi parlak galaksilerin (Brightest Cluster Galaxy - BCG) etkinlik türlerine göre sınıflandırılmasıdır. Çalışma kapsamında, SDSS (Sloan Digital Sky Survey) gökyüzü tarama verileri kullanılarak \citet{hao10} ve \citet{wen09} tarafından sunulan BCG katalogları ile birlikte CFHTLS (Canada-France-Hawaii Telescope Legacy Surve) Derin alanlarından belirlenen \citep{salis09} BCG'ler birleştirilmiştir. Sonuçta elde ettiğimiz 42.490 galaksinin SDSS optik bölge tayf verileri kullanılarak BPT; WISE kırmızıöte fotometrik parlaklıkları kullanılarak iki renk diyagramları oluşturulmuş ve bu yolla galaksilerin etkinlik türleri belirlenmiştir. Ayrıca, tayf verisini elde edebildiğimiz 5569 merkezi parlak galaksinin H${\alpha}$ emisyon çizgileri kullanılarak yıldız oluşum hızları (Star Formation Rate - SFR) hesaplanmış ve yıldız oluşum hızlarının kırmızıya kayma (z) ile değişimi incelenmiştir.
