Can "premature collapse" form black holes in the upper and lower mass gaps?
Thomas W. Baumgarte, Stuart L. Shapiro
Observations of gravitational waves from binary black hole mergers, including the recent signals GW231123 and GW230529, have revealed multiple progenitor black holes in the so-call…

Boosting the growth of intermediate-mass black holes: collisions with massive stars
Thomas W. Baumgarte, Stuart L. Shapiro
We perform fully relativistic simulations of the head-on collisions between intermediate-mass black holes and very massive stars. Such collisions are expected to occur in dense ste…

Extracting the Temperature Analytically In Hydrodynamics Simulations with Gas and Radiation Pressure
Thomas W. Baumgarte, Stuart L. Shapiro
Numerical hydrodynamics simulations of gases dominated by ideal, nondegenerate matter pressure and thermal radiation pressure in equilibrium entail finding the temperature as part…
