Multidisciplinary Science in the Multimessenger Era
Eric Burns, Christopher L. Fryer, Ivan Agullo +82
Astrophysical observations of the cosmos allow us to probe extreme physics and answer foundational questions on our universe. Modern astronomy is increasingly operating under a hol…
Radiation-Hydrodynamics Effects in an Inhomogeneous Medium
Christopher L. Fryer, Paul A. Keiter, Vidushi Sharma +9
Radiation flow through an inhomogeneous medium is critical in a wide range of physics and astronomy applications from transport across cloud layers on the earth to the propagation…
High-Energy Density Hohlraum Design Using Forward and Inverse Deep Neural Networks
Ryan G. McClarren, I. L. Tregillis, Todd J. Urbatsch +1
We present a study of using machine learning to enhance hohlraum design for opacity measurement experiments. For opacity experiments we desire a hohlraum that, when its interior wa…
Designing Radiation Transport Tests: Simulation-Driven Uncertainty-Quantification of the COAX Temperature Diagnostic
Chris L. Fryer, Abdourahmane Diaw, Chris J. Fontes +6
One of the difficulties in developing accurate numerical models of radiation flow in a coupled radiation-hydrodynamics setting is accurately modeling the transmission across a boun…
Radiation Transport Through Super-Eddington Stellar Winds
Joyce A. Guzik, Chris Fryer, Todd J. Urbatsch +1
We present results of simulations to assess the feasibility of modeling outflows from massive stars using the Los Alamos 3-D radiation hydrodynamics code Cassio developed for inert…
Analytic Closures for M1 Neutrino Transport
Lena Murchikova, Ernazar Abdikamalov, Todd Urbatsch
Carefully accounting for neutrino transport is an essential component of many astrophysical studies. Solving the full transport equation is too expensive for most realistic applica…
Unified 1-D Simulations of Gamma-Ray Line Emission from Type Ia Supernovae
P. A. Milne, A. L. Hungerford, C. L. Fryer +9
The light curves of Type Ia Supernovae (SN Ia) are powered by gamma-rays emitted by the decay of radioactive elements such as Ni and its decay products. These gamma-rays are…
