Resolving the black hole sphere of influence in a hyper-luminous obscured quasar at redshift 4.6
Mai Liao, Roberto J. Assef, Chao-Wei Tsai +17
Supermassive black holes (SMBHs) imprint gravitational signatures on the matter within their sphere of influence (SoI). Nuclear gas dynamics can hence be used to accurately measure…

The orbital period of the long-period and colliding-wind binary WR 146 from radio interferometry of the shock cone
Shiming Wen, Bo Zhang, Shuangjing Xu +8
We report the first measurement of the orbital period of a long-period colliding-wind binary (CWB) system WR 146, derived by tracing the rotational morphology of its wind-colliding…
