The origin of the heavy elements
HEAVYMETAL is a project to uncover the nuclear and astrophysical pathways leading to the creation of the rapid neutron capture elements

Scientific Transformational Potential
Neutron star mergers will allow us to explore key questions in astrophysics, cosmology, and fundamental physics

The formation of the heavy elements
- The nuclear & astrophysical pathways of the r-process
- Cosmic chemical enrichment
- Atomic data for astrophysical plasmas
Cosmology and astrophysics
- Astronomical transient interpretation
- Cosmological distance measurement
- Improved masses and spins for gravitational wave sources


Nuclear matter, quarks, neutrinos, gravitational waves, black holes
- Interactions of ultra-dense matter
- QCD phase transition to quark matter
- Physics beyond the standard model in mergers
- Merger dynamics
- Black hole formation
Working together to solve a cosmic mystery
HEAVYMETAL combines the expertise of four research groups across Europe to investigate how neutron star mergers make the r-process elements


Astronomical Observations
Rapid transient follow-up

Merger Simulations
Merger ejecta modelling

Radiation Transport
Time-dependent, 3D radiative transfer

Laser Plasma Spectroscopy
Using laser-produced plasmas to measure atomic data for the heavy elements

Atomic Theory
Theoretical atomic structure calculations

Nucleosynthesis
Understanding the rapid neutron capture process
We will trace the nucleosynthesis pathways in NS mergers, provide insights on heavy nuclei, neutrino interactions and the nature of high-density matter. We will chart the role of compact object mergers as the cosmic forge of the heaviest elements.
