Flux enhancement of corotating hot spots in accretion disks from the slow-light effect
Qing-Hua Zhu
With the Event Horizon Telescope and future Very Long Baseline Interferometry arrays poised to image supermassive black holes, there is a strong motivation to understand the dynami…
The Terrell-Penrose effect revisited and extended for black hole spacetime
Qing-Hua Zhu
Half a century ago, Terrell and Penrose independently studied the visual appearance of a moving sphere and found that the visual distortion can be formulated by a conformal transfo…
Observational signatures from higher-order images of moving hotspots in accretion disks
Qing-Hua Zhu
The efforts to probe the horizon-scale structure of black holes, such as Event Horizon Telescope and GRAVITY interferometer, might provide valuable insights into the strong-field r…
Aberration effect on lower-order images of thin accretion disk in the astrometric approach
Qing-Hua Zhu
With recent advancements in observing supermassive black holes with the Event Horizon Telescope, there has been persistent exploration into what the images can reveal about fundame…
