Observational Evidence for Hot Wind Impact on pc-scale in Low-luminosity Active Galactic Nucleus

Fangzheng Shi, Feng Yuan, Zhiyuan Li +2

Supermassive black holes in galaxies spend majority of their lifetime in the low-luminosity regime, powered by hot accretion flow. Strong winds launched from the hot accretion flow…

First Sagittarius A* Event Horizon Telescope Results. VI: Testing the Black Hole Metric

The Event Horizon Telescope Collaboration

Astrophysical black holes are expected to be described by the Kerr metric. This is the only stationary, vacuum, axisymmetric metric, without electromagnetic charge, that satisfies…

Old supernova dust factory revealed at the Galactic center

Ryan M. Lau, Terry L. Herter, Mark R. Morris +2

Dust formation in supernova ejecta is currently the leading candidate to explain the large quantities of dust observed in the distant, early Universe. However, it is unclear whethe…
