Diverse Origins of Broad H Lines in Heavily Obscured AGNs Revealed by Multi-epoch Spectroscopy
Shoichiro Mizukoshi, Takeo Minezaki, Subaru Ubukata +8
According to the classical AGN model, broad emission lines originate from the broad-line region (BLR) and are observable only when the attenuation by the dusty torus is small. Howe…

XRISM Spectroscopy of Accretion-Driven Wind Feedback in NGC 4151
Xin Xiang, Jon M. Miller, Ehud Behar +17
The hottest, most ionized, and fastest winds driven by accretion onto massive black holes have the potential to reshape their host galaxies. Calorimeter-resolution X-ray spectrosco…
