Gamma-rays from kilonovae and the cosmic gamma-ray background
Pilar Ruiz-Lapuente, Oleg Korobkin
The recent detection of the gravitational wave event GW170817, produced by the coalescence of two neutron stars, and of its optical-infrared counterpart, powered by the radioactive…
Impact of Pulsar and Fallback Sources on Multifrequency Kilonova Models
Ryan T. Wollaeger, Chris L. Fryer, Christopher J. Fontes +6
We explore the impact of pulsar electromagnetic dipole and fallback accretion emission on the luminosity of a suite of kilonova models. The pulsar models are varied over pulsar mag…
Full Transport Model of GW170817-Like Disk Produces a Blue Kilonova
Jonah M. Miller, Benjamin R. Ryan, Joshua C. Dolence +7
The 2017 detection of the inspiral and merger of two neutron stars in gravitational waves and gamma rays was accompanied by a quickly-reddening transient. Such a transient was pred…
Gamma-rays from kilonova: a potential probe of r-process nucleosynthesis
Oleg Korobkin, Aimee M. Hungerford, Christopher L. Fryer +11
The mergers of compact binaries with at least one neutron star component are the potential leading sites of the production and ejection of -process elements. Discoveries of gala…
Composition Effects on Kilonova Spectra and Light Curves: I
Wesley Even, Oleg Korobkin, Christopher L. Fryer +7
The merger of neutron star binaries is believed to eject a wide range of heavy elements into the universe. By observing the emission from this ejecta, scientists can probe the ejec…
A line-binned treatment of opacities for the spectra and light curves from neutron star mergers
C. J. Fontes, C. L. Fryer, A. L. Hungerford +2
The electromagnetic observations of GW170817 were able to dramatically increase our understanding of neutron star mergers beyond what we learned from gravitational waves alone. The…
