Current Steiner Research Group Funding

National Science Foundation
NSF grant, AST 22-06322
Incorporate rapid r-process observations systematically into joint inference about NS population properties and the equation of state (EOS), allowing for alternatives, to assess the origin of r-process elements. This funding ends 11/30/2025.

National Science Foundation
NSF grant, PHY 21-16686
The Nuclear Physics of Multi-Messenger Mergers Focus Research Hub, which aims to understand the nuclear physics of neutron star mergers. Steiner is the PI of this $3.25M collaboration which maintains a separate website at

Oak Ridge National Laboratory
A Joint Faculty appointment with ORNL
Equation of state constraints from neutron star mass and radius observations; Determination of the composition of accreted neutron star crusts using nuclear reaction networks

National Science Foundation
NSF grant, PHY 21-03680
MUSES, Modular Unified Solver of the Equation of State, which will create a new cyber infrastructure for the equation of state for nuclear astrophysics.

National Science Foundation
NSF grant, AST 19-09490
Constrain the nature of dense nuclear matter and to determine whether NS mergers alone explain the abundances of r-process elements. This funding ends 6/30/23.

Department of ENERGY
DOE SciDAC grant, DE-SC0018232
The SciDAC4 project entitled "Towards Exascale Astrophysics of Mergers and Supernovae (TEAMS)" is a collaboration among 8 universities and 4 national laboratories. For this grant, we are constructing new equation of state and neutrino opacity libraries for use in simulations of core-collapse supernovae and neutron star mergers. For more information, visit the TEAMS web page. This funding ends 8/31/22 but a one year no cost extension is planned.

National Science Foundation
A NSF CAREER award, PHY 15-54876
The determination of the EOS and superfluid properties of dense matter from observations of isolated and accreting neutron stars using nucleon and hyperon degrees of freedom. This funding ends 6/30/22.
