Ejection–accretion connection in NLS1 AGN 1H 1934-063

Accretion and ejection of matter in active galactic nuclei (AGN) are tightly connected phenomena represent fundamental mechanisms regulating the growth central supermassive black hole evolution host galaxy. However, exact physical processes involved not yet fully understood. We present a high-resolution spectral analysis simultaneous \xmm\ \nustar\ observation narrow line Seyfert 1 (NLS1) AGN 1H 1934-063, during which X-ray flux dropped by factor $\sim6$ subsequently recovered within 140 kiloseconds. By means time-resolved flux-resolved spectroscopy, we discover potentially variable warm absorber relatively stable ultra-fast outflow (UFO, $v_\mathrm{UFO}\sim-0.075\,c$) with mild ionization state ($\log(\xi/\mathrm{erg\,cm\,s^{-1})}\sim1.6$). The detected emission lines (especially strong broad feature around 1\,keV) unknown origin cannot be explained from plasmas photo- or collisional-ionization equilibrium. Such could well described strongly blueshifted ($z\sim-0.3$) secondary reflection off base equatorial outflows, may reveal link between reprocessing inner accretion flow photons ejection. this scenario although being very promising is only tentative will tested future observations.
