The Effect of the Velocity Distribution on Kilonova Emission
Chris L. Fryer, Aimee L. Hungerford, Ryan T. Wollaeger +7
The electromagnetic emission from the non-relativistic ejecta launched in neutron star mergers (either dynamically or through a disk wind) has the potential to probe both the total…
Surrogate light curve models for kilonovae with comprehensive wind ejecta outflows and parameter estimation for AT2017gfo
Atul Kedia, Marko Ristic, Richard O'Shaughnessy +6
The electromagnetic emission resulting from neutron star mergers have been shown to encode properties of the ejected material in their light curves. The ejecta properties inferred…
Kilonova Detectability with Wide-Field Instruments
Eve A. Chase, Brendan O'Connor, Christopher L. Fryer +7
Kilonovae are ultraviolet, optical, and infrared transients powered by the radioactive decay of heavy elements following a neutron star merger. Joint observations of kilonovae and…
Heavy element nucleosynthesis associated with a gamma-ray burst
James H. Gillanders, Eleonora Troja, Chris L. Fryer +9
Kilonovae are a novel class of astrophysical transients, and the only observationally-confirmed site of rapid neutron capture nucleosynthesis (the r-process) in the Universe. To da…
Interpolated kilonova spectra models: necessity for a phenomenological, blue component in the fitting of AT2017gfo spectra
Marko Ristic, Richard O'Shaughnessy, V. Ashley Villar +5
In this work, we present a simple interpolation methodology for spectroscopic time series, based on conventional interpolation techniques (random forests) implemented in widely-ava…
