A search for relativistic outflows signatures in the X-ray spectra of radio-quiet AGNs
We performed a blind search for blue-shifted Fe K absorption lines at energies greater than 6 keV in the X-ray spectra of a sample of 44 radio-quiet AGNs observed with XMM-Newton. We statistically quantified the parameters and the incidence of such lines and also determined then-detection significan...

| description | We performed a blind search for blue-shifted Fe K absorption lines at energies greater than 6 keV in the X-ray spectra of a sample of 44 radio-quiet AGNs observed with XMM-Newton. We statistically quantified the parameters and the incidence of such lines and also determined then-detection significance through extensive Monte Carlo simulations. This allows us to define their global veracity and to overcome the reported publication bias. These findings suggest the presence of previously unknown ultra-fast outflows in radio-quiet AGNs. |
