Simulating the Extremes of Spacetime

Black holes represent the ultimate test for High-Performance Computing. From the photon-bending optics of the Event Horizon to the violent ripples of Gravitational Waves, Malgukke provides the GPU-accelerated architectures required to model these non-linear phenomena.

Accretion Ray-Tracing

Visualizing light paths around Event Horizons using GPU-accelerated solvers. We solve the Null Geodesic equations to resolve the shadow and photon rings of supermassive black holes.

  • Kerr-Metric Geodesic Solvers
  • General Relativistic Magnetohydrodynamics (GRMHD)

Gravitational Waves

Modeling binary black hole and neutron star mergers to predict precise waveforms. These "templates" are critical for data matching in LIGO, Virgo, and KAGRA detector arrays.

  • Numerical Relativity (BSSN & Z4 formulations)
  • Inspiral-Merger-Ringdown (IMR) Waveforms
