Outflows from active galactic nuclei (AGNs) are one of the fundamental mechanisms by
which the central supermassive black hole interacts with its host galaxy. Detected in≥ 50 …

The mechanism of thermal driving for launching mass outflows is interconnected with
classical thermal instability (TI). In a recent paper, we demonstrated that as a result of this …

Warm absorbers are present in many active galactic nuclei (AGN), seen as mildly ionized
gas outflowing with velocities of a few hundred to a few thousand kilometres per second …

For many years we have known that dust in the form of a dusty-molecular torus is
responsible for the obscuration in active galactic nuclei (AGN) at large viewing angles and …

Changing-look active galactic nuclei (CLAGNs) show a complex nature in their X-ray
spectral shape and line-of-sight column-density variation. The physical mechanisms …

To investigate the origins of the warm absorbers in active galactic nuclei (AGNs), we study
the ionization-state structure of the radiation-driven fountain model in a low-mass AGN and …

We present a set of new theoretical Fe II templates for bright quasars covering a wavelength
range of 1000-10000\AA, based on the recent atomic database available in the C23. 00 …

We study the multiphase medium in the vicinity of the active galactic nucleus Centaurus A
(Cen A). Combined high-resolution observations with the Atacama Large Millimeter …

ABSTRACT X-ray flux from the inner hot region around central compact object in a binary
system illuminates the upper surface of an accretion disc and it behaves like a corona. This …

To reveal basic properties of obscuring material in active galactic nuclei (AGNs) is important
for understanding feeding and feedback mechanisms of AGNs. The unified model of AGNs …
