QWIND3: UV line-driven accretion disc wind models for AGN feedback

Image

Quera-Bofarull, Arnau,   Done, Chris,   Lacey, Cedric G.,   Nomura, Mariko,   Ohsuga, Ken

The ultraviolet (UV) bright accretion disc in active galactic nuclei (AGNs) should give rise to line driving, producing a powerful wind that may play an important role in AGN feedback as well as in producing structures like the broad-line region. How...

Image

Yoshioka, Shogo,   Mineshige, Shin,   Ohsuga, Ken,   Kawashima, Tomohisa,   Kitaki, Takaaki

In order to evaluate the impacts made by super-Eddington accretors on their environments precisely, it is essential to guarantee a large enough simulation box and long computational time to avoid any artefacts from numerical settings as much as possi...

Fabbiano, G.,   Paggi, A.,   Morganti, R.,   Baloković, M.,   Elvis, M.,   Mukherjee, D.

We report the results of joint Chandra/ACIS-NuSTAR deep observations of NGC 1167, the host galaxy of the young radio jet B2 0258+35. In the ACIS data, we detect X-ray emission, extended both along and orthogonal to the jet. At the end of the southeas...

The formation of the first quasars: the black hole seeds, accretion, and feedback models

Image

Zhu, Qirong,   Li, Yuexing,   Li, Yiting,   Maji, Moupiya,   Yajima, Hidenobu,   Schneider, Raffaella

Supermassive black holes (SMBHs) of ~ 109 M⊙ are generally believed to be the central engines of the luminous quasars observed at z ≳ 6, but their astrophysical origin remains elusive. To investigate the formation of these distant quasars, we perform...
