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…
3D magnetised jet break-out from neutron-star binary merger ejecta: afterglow emission from the jet and the ejecta
Antonios Nathanail, Ramandeep Gill, Oliver Porth +2
We perform three-dimensional (3D) general-relativistic magnetohydrodynamic simulations to model the jet break-out from the ejecta expected to be produced in a binary neutron-star m…
MPI-AMRVAC: a parallel, grid-adaptive PDE toolkit
Rony Keppens, Jannis Teunissen, Chun Xia +1
We report on the latest additions to our open-source, block-grid adaptive framework MPI-AMRVAC, which is a general toolkit for especially hyperbolic/parabolic partial differential…
SYMBA: An end-to-end VLBI synthetic data generation pipeline
F. Roelofs, M. Janssen, I. Natarajan +203
Realistic synthetic observations of theoretical source models are essential for our understanding of real observational data. In using synthetic data, one can verify the extent to…
On the opening angle of magnetised jets from neutron-star mergers: the case of GRB170817A
Antonios Nathanail, Ramandeep Gill, Oliver Porth +2
The observations of GW170817/GRB170817A have confirmed that the coalescence of a neutron-star binary is the progenitor of a short gamma-ray burst. In the standard picture of a shor…
Plasmoid formation in global GRMHD simulations and AGN flares
Antonios Nathanail, Christian M. Fromm, Oliver Porth +4
One of the main dissipation processes acting on all scales in relativistic jets is thought to be governed by magnetic reconnection. Such dissipation processes have been studied in…
