Aşırı-parlak X-ışın kaynakları (AXK, Ultraluminous X-ray sources), X-ışın çiftlerinin bir alt sınıfı olarak tanımlanmaktadır. Galaksimizde henüz gözlenemeyen AXK'lar, diğer galaksilerin merkez bölgesi dışında ve ışıma gücü çok yüksek (L$_{x} > 10^{39}$ erg s$^{-1}$) kütlesi $\sim 10M_{\odot}$ nokta-kaynaklar olarak algılanmaktadır. Bu sunumda, AXK’ların genel özellikleri, fiziksel doğasının anlaşılması için yapılan çoklu dalga boyu (X-ışın, optik, kızıl-öte) gözlemleri ve sonuçları özetlenecektir. Çalışmalarımız kapsamında seçilen bazı AXK’ların zamansal, tayfsal analizleri, belirlenen optik karşılıkları incelenecektir.
