Relativistic collapse
World-time description of collapse, gravitational freezing and compact-object structure.
RELATIVISTIC GRAVITATION AND COMPACT OBJECTS
General Relativity
Research on the physical interpretation and applications of general relativity, with emphasis on collapse, global time and compact objects.
MAIN THEMES
Relativistic gravitation
Oppenheimer–Snyder dust star
Consistency of the dust-star solution, its coordinate transformation and matching to the external Schwarzschild geometry.
Charged and rotating sources
Parameter dependence of gravitational effects when mass, charge and angular momentum are physically separated.
Metric time and relativistic observables
Work on the interpretation of time standards and on observable effects controlled by gravitational slowing of local physical processes.
