Do Image Editors Follow Depth-Dependent Blur and Aperture Response? A Rendered-Ground-Truth Pilot Audit
Zhihan Chen, Yuhuan Zhao, Yijie Zhu +4
General image editors are asked to make a photo look as if it were taken at f/1.4, yet it is rarely checked whether the blur they add follows thin-lens optics. A physical aperture…
Kilonova Light-Curve Interpolation with Neural Networks
Yinglei Peng, Marko Ristić, Atul Kedia +7
Kilonovae are the electromagnetic transients created by the radioactive decay of freshly synthesized elements in the environment surrounding a neutron star merger. To study the fun…
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…
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…
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…
Constraining inputs to realistic kilonova simulations through comparison to observed -process abundances
M. Ristic, E. M. Holmbeck, R. Wollaeger +7
Kilonovae, one source of electromagnetic emission associated with neutron star mergers, are powered by the decay of radioactive isotopes in the neutron-rich merger ejecta. Models f…
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…
A Broad Grid of 2D Kilonova Emission Models
R. T. Wollaeger, C. L. Fryer, E. A. Chase +6
Depending upon the properties of their compact remnants and the physics included in the models, simulations of neutron star mergers can produce a broad range of ejecta properties.…
Interpolating Detailed Simulations of Kilonovae: Adaptive Learning and Parameter Inference Applications
M. Ristic, E. Champion, R. O'Shaughnessy +6
Detailed radiative transfer simulations of kilonovae are difficult to apply directly to observations; they only sparsely cover simulation parameters, such as the mass, velocity, mo…
Minimum Orbital Period of Pre-Cataclysmic Variables
L. Nelson, J. Schwab, M. Ristic +1
More than 20 pre-cataclysmic variable (pre-CV) systems have now been discovered with very short orbital periods ranging from 250 min down to 68 min. A pre-CV consists of a white dw…
