Abstract

Spitzer/IRAC renk seçimi, galaksilerdeki sıcak madde biriktiren çekirdekleri, bir başka ifadeyle AGN'i tanımlamak için güçlü bir araçtır. Bu çalışmada İkiz et al., (2020) tarafından 2500’den fazla galaksiden oluşan Galaksilerdeki Yıldız Yapılarının Spitzer Araştırması (S4G) örneklemesine ek olarak onun uzantısı 400 galaksiden oluşan örneklemeden orta-kırmızı öte renk seçim yöntemi ile seçilmiş 36 AGN kullanılmıştır. Kırmızı ötesi renk seçimi yöntemi, XMM-Newton ve Chandra verileri ile galaksilerin X-ışını özellikleri incelenerek test edilmiştir. X-ışını verilerini kullanarak, sıcak orta kırmızı ötesi çekirdek sergileyen galaksilerin (aday) aktif galaksiler olarak öne çıktığı gösterilmiştir. Orta-kırmızı ötesi seçilmiş AGN'lerin %64'ü XMM-Newton ve Chandra verilerinde X-ışını enerjilerinde tespit edilmiştir. X-ışını tespitleri olmayan AGN renklerine sahip IRAC kaynakların büyük çoğunluğunun yüksek ışıtmalı örtülmüş AGN’ler olduğu varsayılmıştır.

X-ray Properties of Spitzer/IRAC Selected AGNs

Abstract

Spitzer/IRAC color selection is a powerful tool to identify hot accreting nuclei, that is to say AGN, in galaxies. In this study, mid-infrared detected candidate 36 AGNs are used that are selected from the Spitzer Survey of Stellar Structures in Galaxies (S4G) sample consisting of more than 2500 galaxies together with its extension sample of more than 400 galaxies by İkiz et al., (2020). Mid-infrared color selection method is tested by examining the X-ray properties of the galaxies via the XMM-Newton and Chandra. Using the X-ray data, we demonstrate that galaxies displaying hot mid-infrared nuclei stand out as (candidate) active galaxies. 64% of mid-infrared-selected AGN are detected at X-ray energies in XMM-Newton and Chandra data. It has been hypothesized that IRAC sources with AGN colors that lack X-ray detections are predominantly high-luminosity AGN that are obscure.
