Impact of ejecta morphology and composition on the electromagnetic signatures of neutron star mergers

Understand

The electromagnetic transients accompanying compact binary mergers ($\gamma$-ray bursts, afterglows and 'macronovae') are crucial to pinpoint the sky location of gravitational wave sources.

• Macronovae are caused by the radioactivity from freshly synthesised heavy elements, e.g.
• from dynamic ejecta and various types of winds.
• We study macronova signatures by using multi-dimensional radiative transfer calculations.
