Relativistic Signatures of Flux Eruption Events Near Black Holes
Zachary Gelles, Koushik Chatterjee, Michael Johnson +2
Images of supermassive black holes produced using very long baseline interferometry provide a pathway to directly observing effects of a highly curved spacetime, such as a bright `…
Tracing the hot spot motion using the next generation Event Horizon Telescope (ngEHT)
Razieh Emami, Paul Tiede, Sheperd S. Doeleman +19
We propose to trace the dynamical motion of a shearing hot spot near the SgrA* source through a dynamical image reconstruction algorithm, StarWarps. Such a hot spot may form as the…
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…
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…
Accelerating AGN jets to parsec scales using general relativistic MHD simulations
Koushik Chatterjee, Matthew Liska, Alexander Tchekhovskoy +1
Accreting black holes produce collimated outflows, or jets, that traverse many orders of magnitude in distance, accelerate to relativistic velocities, and collimate into tight open…
The Event Horizon General Relativistic Magnetohydrodynamic Code Comparison Project
Oliver Porth, Koushik Chatterjee, Ramesh Narayan +25
Recent developments in compact object astrophysics, especially the discovery of merging neutron stars by LIGO, the imaging of the black hole in M87 by the Event Horizon Telescope (…
