2. 1. Jet-wind interaction in neutron star mergers

   Author : Lorenzo Nativi; Stephan Rosswog; Jesper Sollerman; Felix Ryde; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; jets; kilonova; macronova; gamma-ray burst; neutron star merger; compact objects; Astronomy; astronomi;

   Abstract : Besides being sources of gravitational waves, there has been evidence that neutron starmergers release neutron-rich material suitable for the production of heavy r-process nuclei.The radioactive decay of these freshly synthesised elements powers a rapidly evolvingthermal transient, the “macronova” (also known as “kilonova”).

4. 2. Kilonova signatures and observations with Zwicky Transient Facility

   Author : Ana Sagués Carracedo; Ariel Goobar; Chad Finley; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; kilonovae - neutron stars - gravitational waves; High Energy Physics; högenergifysik; Physics; fysik;

   Abstract : On 17 August 2017, the advanced LIGO and Virgo collaboration detected the first gravitational wave event produced by the merger of a pair of inspiraling binary neutron stars (BNS). This event, named GW170817, was associated with a short gamma-ray burst and the kilonova (KN) AT2017gfo that was followed-up over the following days and weeks over the electromagnetic spectrum from ultraviolet to near infrared frequencies.

5. 3. Jet-Ejecta Interactions in Neutron Star Mergers : How jets interacting with the surroundings affect multi-wavelength observations

   Author : Lorenzo Nativi; Stephan Rosswog; Miguel Aloy; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrodynamics; relativistic processes; jets; gamma-ray bursts; neutron star mergers; macronova; Astronomy; astronomi;

   Abstract : In August 2017 a gravitational wave signal from a binary neutron star merger was detected for the first time, and it was followed by several electromagnetic detections that spanned the whole electromagnetic spectrum. Those observations proved the ejection of two dynamical components: mildly-relativistic neutron rich ejecta and an ultra-relativistic jet. READ MORE

6. 4. Non-Local Thermodynamic Equilibrium Spectral Modelling of Kilonovae

   Author : Quentin Pognan; Anders Jerkstrand; Kyohei Kawaguchi; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transients: Neutron Star Mergers; Radiative Transfer; Astronomy; astronomi;

   Abstract : The astrophysical origin of rapid neutron capture (r-process) elements has long remained a puzzle and been the object of scientific debate. Neutron star (NS) mergers have historically been suggested as an ideal site for the creation of these elements, and were propelled into focus following the detection of the first binary neutron star (BNS) merger in 2017.
