Abstract: We briefly review how X-ray observations of high-redshift active galactic nuclei (AGNs) at z = 4–7 have played a critical role in understanding their basic demographics as well as their physical processes; for example, absorption… read more here.

DOI: 10.1093/mnras/staa2320
Abstract: We present the results of deep Chandra and XMM-Newton observations of a complex merging galaxy cluster Abell 2256 (A2256) that hosts a spectacular radio relic (RR). The temperature and metallicity maps show clear evidence of… read more here.
