S 4G Örneklemesi: WISE, 3XMM ve FIRST/NVSS ile AGN'lerin Soğurma Özellikleri

Bu çalışmada, 2500’den fazla galaksiden oluşan Galaksilerdeki Yıldız Yapılarının Spitzer Araştırması (S4G) örneklemesine ek olarak onun uzantısı 400 galaksiden oluşan örneklemeden IRAC 3.6 ve 4.5 ve WISE 3.4 ve 4.6 μm de orta-kırmızı öte renkleri İkiz vd. (2020) tarafından hesaplanmış galaksiler hem XMM-Newton hem de radyo arşivlerde taranarak eşlenikleri bulunmuş ve aktivitelerine dayanarak, radyo-gürültülü ve radyosessiz aktif galaktik çekirdekler olarak sınıflandırılmıştır. Galaksilerin soğurma özellikleri sertlik oranlarına göre belirlenmiştir.

The S4G Sample: Absorption Properties of AGNs with WISE, 3XMM, and FIRST/NVSS

In this study, mid-infrared colours were calculated by İkiz et al. (2020) at IRAC 3.6 and 4.5 and WISE 3.4 and 4.6 μm from the Spitzer Stellar Structure Survey in Galaxies – S 4G sample consisting of more than 2500 galaxies, in addition to its extension, from a sample of 400 galaxies were examined in X-ray 3XMM-DR5 and in radio VLA NVSS and FIRST archives to find their counterparts and classified as radio-loud and radio-quiet active galactic nuclei based on their activity. The absorption properties of galaxies were determined according to the hardness ratios.
