Accretion onto a moving black hole for stiff equations of state
Elliott Ewell, Peter K. Harris, Thomas W. Baumgarte +1
We revisit accretion of an asymptotically uniform fluid onto a moving Schwarzschild black hole, the relativistic analog of Bondi-Hoyle-Lyttleton accretion. Expanding on previous tr…
Subsolar mass black holes from stellar collapse induced by primordial black holes
Thomas W. Baumgarte, Stuart L. Shapiro
While no gravitational-wave detection of subsolar mass black holes has been confirmed to date, a number of candidate detections invite us to speculate on the origin of such black h…
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…
Constraining the nuclear equation of state from orbits of primordial black holes inside neutron stars
Anna Chen, Juan Diego DelPrado, Thomas W. Baumgarte +1
Lacking terrestrial experimental data, our best constraints on the behavior of matter at high densities up to and above nuclear density arise from observations of neutron stars. Cu…
