Demographics of black holes at 100 R scales: accretion flows, jets, and shadows
Dhanya G. Nair, Neil M. Nagar, Venkatessh Ramakrishnan +87
Using the Event Horizon Telescope (EHT), the gravitationally lensed rings around the supermassive black holes (SMBHs) in Messier 87 (M87) and Sagittarius A* (Sgr A*) have now been…
Probing jet dynamics and collimation in radio galaxies. Application to NGC 1052
Ainara Saiz-Pérez, Christian M. Fromm, Manel Perucho +5
Context. Radio galaxies with visible two-sided jet structures, such as NGC 1052, are sources of particular interest to study the collimation and shock structure of active galactic…
Numerical Investigation of Instabilities in Over-pressured Magnetized Relativistic Jets
Xu-Fan Hu, Yosuke Mizuno, Christian M. Fromm
Context. Relativistic jets from Active Galactic Nuclei are observed to be collimated on the parsec scale. When the pressure between the jet and the ambient medium is mismatched, re…
The impact of resistivity on the variability of black hole accretion flows
Antonios Nathanail, Yosuke Mizuno, Ioannis Contopoulos +4
Context. The accretion of magnetized plasma onto black holes is a complex and dynamic process, where the magnetic field plays a crucial role. The amount of magnetic flux accumulate…
First Very Long Baseline Interferometry Detections at 870μm
Alexander W. Raymond, Sheperd S. Doeleman, Keiichi Asada +276
The first very long baseline interferometry (VLBI) detections at 870m wavelength (345GHz frequency) are reported, achieving the highest diffraction-limited angular resolutio…
