Self-lensing flares from black hole binaries II: observing black hole shadows via light-curve tomography
Jordy Davelaar, Zoltán Haiman
Supermassive black hole (BH) binaries are thought to produce self-lensing flares (SLF) when the two BHs are aligned with the line-of-sight. If the binary orbit is observed nearly e…
Self-lensing flares from black hole binaries I: general-relativistic ray tracing of black hole binaries
Jordy Davelaar, Zoltán Haiman
The self-lensing of a massive black hole binary (MBHB), which occurs when the two BHs are aligned close to the line of sight, is expected to produce periodic, short-duration flares…
Event Horizon Telescope observations of the jet launching and collimation in Centaurus A
Michael Janssen, Heino Falcke, Matthias Kadler +236
Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…
Impact of non-thermal particles on the spectral and structural properties of M87
Christian M. Fromm, Alejandro Cruz-Osorio, Yosuke Mizuno +8
The recent 230 GHz observations of the Event Horizon Telescope (EHT) are able to image the innermost structure of the M87 and show a ring-like structure which is in agreement with…
State-of-the-art energetic and morphological modelling of the launching site of the M87 jet
Alejandro Cruz-Osorio, Christian M. Fromm, Yosuke Mizuno +7
M87 has been the target of numerous astronomical observations across the electromagnetic spectrum and Very Long Baseline Interferometry (VLBI) resolved an edge-brightened jet. Howe…
The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale
Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel +235
The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center o…
