Gravitational Test Beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole
Dimitrios Psaltis, Lia Medeiros, Pierre Christian +185
The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new…
Spectral and Imaging properties of Sgr A* from High-Resolution 3D GRMHD Simulations with Radiative Cooling
Doosoo Yoon, Koushik Chatterjee, Sera Markoff +4
The candidate supermassive black hole in the Galactic Centre, Sagittarius A* (Sgr A*), is known to be fed by a radiatively inefficient accretion flow (RIAF), inferred by its low ac…
Monitoring the Morphology of M87* in 2009-2017 with the Event Horizon Telescope
Maciek Wielgus, Kazunori Akiyama, Lindy Blackburn +26
The Event Horizon Telescope (EHT) has recently delivered the first resolved images of M87*, the supermassive black hole in the center of the M87 galaxy. These images were produced…
Observational signatures of disk and jet misalignment in images of accreting black holes
Koushik Chatterjee, Ziri Younsi, Matthew Liska +7
Black hole accretion is one of nature's most efficient energy extraction processes. When gas falls in, a significant fraction of its gravitational binding energy is either converte…
On the Role of Hot Feedback Mode in Active Galactic Nuclei Feedback in an Elliptical Galaxy
Doosoo Yoon, Feng Yuan, Jeremiah P. Ostriker +2
Depending on the value of the accretion rate, black hole accretion is divided into cold and hot modes. The two modes have distinctly different physics and correspond to two feedbac…
Numerical study of active galactic nucleus feedback in an elliptical galaxy with {\it MACER}
Feng Yuan, Jeremiah P. Ostriker, DooSoo Yoon +5
This paper summarizes our recent works of studying AGN feedback in an isolated elliptical galaxy by performing high-resolution hydrodynamical numerical simulations. Bondi radius is…
