Relativistic outflows from a GRMHD mean-field disk dynamo
Christos Vourellis, Christian Fendt
We present simulations of thin accretion disks around black holes investigating a mean-field disk dynamo in our resistive GRMHD code (Vourellis et al. 2019) that is able to produce…
General relativistic radiation transport: Implications for VLBI/EHT observations of AGN discs, winds and jets
Bidisha Bandyopadhyay, Christian Fendt, Dominik R. G. Schleicher +1
In 2019, the Event Horizon Telescope Collaboration (EHTC) has published the first image of a supermassive black hole (SMBH) obtained via the Very Large Baseline Interferometry (VLB…
GR-MHD disk winds and jets from black holes and resistive accretion disks
Christos Vourellis, Christian Fendt, Qian Qian +1
We perform GR-MHD simulations of outflow launching from thin accretion disks. As in the non-relativistic case, resistivity is essential for the mass loading of the disk wind. We im…
Jet launching in resistive GR-MHD black hole - accretion disk systems
Qian Qian, Christian Fendt, Christos Vourellis
We investigate the launching mechanism of relativistic jets from black hole sources, in particular the strong winds from the surrounding accretion disk. Numerical investigations of…
