One of the main open questions in the field of luminous (L bol> 10 47 erg s− 1) quasars
(QSOs) at z≳ 6 is the rapid formation (< 1 Gyr) of their supermassive black holes (SMBHs) …

Outflows are critical components of many astrophysical systems, including accreting
compact binaries and active galactic nuclei (AGN). These outflows can significantly affect a …

Understanding the links between different phases of outflows from active galactic nuclei is a
key goal in extragalactic astrophysics. Here we compare [O iii] λλ4960, 5008 outflow …

We study active galactic nucleus (AGN) line-driven disc winds using time-dependent
radiation hydrodynamics. The key criterion for determining wind launching is the coupling …

Flows driven by photons have been studied for almost a century, and a quantitative
description of the radiative forces on atoms and ions is important for understanding a wide …

The supermassive black holes ($ M_ {\rm BH}\sim 10^{6} $$-$ $10^{10}~ M_\odot $) that
power luminous active galactic nuclei (AGNs), ie, quasars, generally show a correlation …

The James Webb Space Telescope (JWST) has recently discovered a new population of
objects at high redshift referred to asLittle Red Dots'(LRDs). Their nature currently remains …

Abstract We present Hubble Space Telescope ultraviolet (UV) of 13 quasars at z< 0.7, along
with contemporaneous optical spectra from ground-based telescopes. The targets were …

This paper presents a preliminary investigation into the influence of radial behavior of disk
outflow on the structure and dynamics of the broad line region (BLR) in active galactic nuclei …
