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…

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…

A Toy Model for the Electromagnetic Output of Neutron-star Merger Prompt Collapse to a Black Hole: Magnetized Neutron-star Collisions

Antonios Nathanail

We present a systematic study of magnetised neutron star head on collisions. We investigate the resulting magnetic field geometries as the two neutron stars merge. Furthermore, we…
