Center for Theoretical Astrophysics: collaborative science

The Center for Theoretical Astrophysics spans a wide range of divisions and directorates. Core scientists reside in the following divisions:

In turn, they work on collaborations with scientists in these divisions:

The Lab has roughly 50 active astrophysicists; 80% of them are permanent staff.

Research Areas
  • Cosmology and the first stars: Cosmology calculations using a broad range of tools (e.g., ENZO and Gadget), focused on studying the formation of the first stars and black holes
  • Active galactic nuclei: Evolution of massive black holes, studying both radiation and magneto-hydrodynamic effects
  • Star and planet formation: Formation of the solar system, extra-solar planets.
  • Engines behind transients: Thermonuclear and core-collapse supernovae, gamma-ray burst, and x-ray burst engines.
  • Nuclear astrophysics: Understanding the behavior of matter and nuclear densities and applying these effects (neutrinos, equations of state) to supernova models
  • Nucleosynthesis: Yields from stars and supernovae, nuclear cross-sections (tying to experiment), galactic chemical evolution
  • Supernova remnants: Following the engine through the remnant phase, effects of NLTE opacities, and magneto-hydrodynamics
  • Emission from astrophysical transients: Modeling spectra and light-curves, radiation-hydrodynamics effects, atomic physics
  • Cosmic rays: Generation and propagation of cosmic rays from gamma-ray bursts and supernovae. Ties to a number of missions (e.g., HAWC, NuSTAR).
  • Experimental astrophysics: Many of the fields leverage laboratory experiments in plasma physics, turbulence, radiation transport, nuclear, and atomic physics.
