Gravitational Wave Eigenfrequencies from Neutrino-Driven Core-Collapse Supernovae
Noah E. Wolfe, Carla Frohlich, Jonah M. Miller +2
Core-collapse supernovae are predicted to produce gravitational waves (GWs) that may be detectable by Advanced LIGO/Virgo. These GW signals carry information from the heart of thes…
Nucleosynthesis in Outflows from Black Hole-Neutron Star Merger Disks With Full GRRMHD
Sanjana Curtis, Jonah M. Miller, Carla Frohlich +3
Along with binary neutron star mergers, the in-spiral and merger of a black hole and a neutron star is a predicted site of -process nucleosynthesis and associated kilonovae. For…
Not-Quite Transcendental Functions and their Applications
Jonah M. Miller, Joshua C. Dolence, Daniel Holladay
Transcendental functions, such as exponentials and logarithms, appear in a broad array of computational domains: from simulations in curvilinear coordinates, to interpolation, to m…
Parthenon -- a performance portable block-structured adaptive mesh refinement framework
Philipp Grete, Joshua C. Dolence, Jonah M. Miller +12
On the path to exascale the landscape of computer device architectures and corresponding programming models has become much more diverse. While various low-level performance portab…
Realistic Kilonova Up Close
Alexandra Ruth Stewart, Li-Ta Lo, Oleg Korobkin +6
Neutron star mergers are cosmic catastrophes that produce some of the most energetic observed phenomena: short gamma-ray bursts, gravitational wave signals, and kilonovae. The latt…
A New Constraint on the Nuclear Equation of State from Statistical Distributions of Compact Remnants of Supernovae
Mikhail M. Meskhi, Noah E. Wolfe, Zhenyu Dai +4
Understanding how matter behaves at the highest densities and temperatures is a major open problem in both nuclear physics and relativistic astrophysics. This physics is often enca…
Black Hole Spin in X-ray Binaries: Giving Uncertainties an
Greg Salvesen, Jonah M. Miller
The two established techniques for measuring black hole spin in X-ray binaries often yield conflicting results, which must be resolved before either method may be deemed robust. In…
Core-Collapse Supernovae: From Neutrino-Driven 1D Explosions to Light Curves and Spectra
Sanjana Curtis, Noah Wolfe, Carla Fröhlich +3
We present bolometric and broadband light curves and spectra for a suite of core-collapse supernova models exploded self-consistently in spherical symmetry within the PUSH framewor…
Axisymmetric Radiative Transfer Models of Kilonovae
Oleg Korobkin, Ryan Wollaeger, Christopher Fryer +9
The detailed observations of GW170817 proved for the first time directly that neutron star mergers are a major production site of heavy elements. The observations could be fit by a…
Full Transport General Relativistic Radiation Magnetohydrodynamics for Nucleosynthesis in Collapsars
Jonah M. Miller, Trevor M. Sprouse, Christopher L. Fryer +4
We model a compact black hole-accretion disk system in the collapsar scenario with full transport, frequency dependent, general relativistic radiation magnetohydrodynamics. We exam…
Enabling real-time multi-messenger astrophysics discoveries with deep learning
E. A. Huerta, Gabrielle Allen, Igor Andreoni +57
Multi-messenger astrophysics is a fast-growing, interdisciplinary field that combines data, which vary in volume and speed of data processing, from many different instruments that…
Spectral shock detection for dynamically developing discontinuities
Joanna Piotrowska, Jonah M. Miller
Pseudospectral schemes are a class of numerical methods capable of solving smooth problems with high accuracy thanks to their exponential convergence to the true solution. When app…
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…
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…
Understanding the Engines and Progenitors of Gamma-Ray Bursts
Chris L. Fryer, Nicole Lloyd-Ronning, Ryan Wollaeger +5
Our understanding of the engines and progenitors of gamma-ray bursts has expanded through the ages as a broader set of diagnostics has allowed us to test our understanding of these…
: Radiation GRMHD for Neutrino-Driven Accretion Flows
Jonah M. Miller, Ben R. Ryan, Joshua C. Dolence
The 2017 detection of the in-spiral and merger of two neutron stars was a landmark discovery in astrophysics. We now know that such mergers are central engines of short gamma ray b…
Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
Constraints on Gamma-ray Burst Inner Engines in a Blandford-Znajek Framework
Nicole M. Lloyd-Ronning, Chris Fryer, Jonah Miller +3
Under the assumption that a Gamma-ray Burst (GRB) is ultimately produced by a Blandford-Znajek (BZ) jet from a highly spinning black hole BH, we put limits on the magnetic field an…
Spectral Methods in the Presence of Discontinuities
Joanna Piotrowska, Jonah M. Miller, Erik Schnetter
Spectral methods provide an elegant and efficient way of numerically solving differential equations of all kinds. For smooth problems, truncation error for spectral methods vanishe…
