We present a new X-ray spectroscopic study of 22 luminous (2× 10 45≲ L bol/erg s− 1≲ 2×
10 46) active galactic nuclei (AGNs) at intermediate redshifts (0.1≲ z≲ 0.4), as part of the …

We present a new implementation for active galactic nucleus (AGN) feedback through small-
scale, ultrafast winds in the moving-mesh hydrodynamic code arepo. The wind is injected by …

Context. The BL Lac object 1ES 0647+ 250 is one of the few distant γ-ray emitting blazars
detected at very high energies (VHEs;≳ 100 GeV) during a non-flaring state. It was detected …

We present a detailed X-ray spectral analysis of the narrow-line Seyfert 1 galaxy I Zwicky 1,
for which a sequence of X-ray flares were detected during a long, simultaneous observation …

Substantial evidence in the last few decades suggests that outflows from supermassive
black holes (SMBH) may play a significant role in the evolution of galaxies. These outflows …

ABSTRACT UltraFast Outflows (UFOs) are observed in some active galactic nuclei (AGN),
with blueshifted and highly ionized Fe-K absorption features. AGN typically have an …

Abstract PG 1448+ 273 is a luminous, nearby (z= 0.0645), narrow-line Seyfert 1 galaxy,
which likely accretes close to the Eddington limit. XMM-Newton observations of PG 1448+ …

Abstract I Zwicky 1 (hereafter I Zw 1) is the prototype optical narrow-line Seyfert 1 galaxy. It is
also a nearby (z= 0.0611), luminous quasi-stellar object (QSO), accreting close to the …

The detection of blueshifted absorption lines likely associated with ionized iron K-shell
transitions in the X-ray spectra of many active galactic nuclei (AGNs) suggests the presence …

Context. Ultra-fast outflows (UFOs) have become an established feature in analyses of the X-
ray spectra of active galactic nuclei (AGN). According to the standard picture, they are …
