Growing black-hole hair in nonminimally coupled biscalar gravity
Chloe Richards, Alexandru Dima, Deborah Ferguson +1
Black holes offer a unique laboratory for fundamental physics and are crucial for probing theories beyond Einstein's theory of General Relativity. In this paper, we consider 4D eff…

Accretion onto a small black hole at the center of a neutron star
Chloe B. Richards, Thomas W. Baumgarte, Stuart L. Shapiro
We revisit the system consisting of a neutron star that harbors a small, possibly primordial, black hole at its center, focusing on a nonspinning black hole embedded in a nonrotati…

Relativistic Bondi accretion for stiff equations of state
Chloe B. Richards, Thomas W. Baumgarte, Stuart L. Shapiro
We revisit Bondi accretion - steady-state, adiabatic, spherical gas flow onto a Schwarzschild black hole at rest in an asymptotically homogeneous medium - for stiff polytropic equa…
