High-Precision Inversion of Dynamic Radiography Using Hydrodynamic Features
Maliha Hossain, Balasubramanya T. Nadiga, Oleg Korobkin +7
Radiography is often used to probe complex, evolving density fields in dynamic systems and in so doing gain insight into the underlying physics. This technique has been used in num…
Multi-messenger-Athena Synergy White Paper
L. Piro, M. Ahlers, A. Coleiro +30
In this paper we explore the scientific synergies between Athena and some of the key multi-messenger facilities that should be operative concurrently with Athena. These facilities…
Modeling Neutron Star Oscillations in a Fixed General Relativistic Background Including Solid Crust Dynamics
Bing-Jyun Tsao, Irina Sagert, Oleg Korobkin +4
Measurements of the gravitational-wave signals from neutron star mergers allow scientists to learn about the interior of neutron stars and the properties of dense nuclear matter. T…
Conservation of Angular Momentum in the Fast Multipole Method
Oleg Korobkin, Hyun Lim, Irina Sagert +5
Smoothed particle hydrodynamics (SPH) is positioned as having ideal conservation properties. When properly implemented, conservation of total mass, energy, and both linear and angu…
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.…
