The weakness of soft X-ray intensity: possible physical reason for weak line quasars
Jiancheng Wu, Qingwen Wu, Chichuan Jin +8
Weak-line quasars (WLQs) are a notable group of active galactic nuclei (AGNs) that show unusually weak UV lines even though their optical-UV continuum shapes are similar to those o…
