Gravity Initiative
The TAP Gravity Initiative brings together researchers from astronomy and physics to study the fundamental laws of gravity and their manifestation in the observable universe, primarily in the extreme environments of black holes and neutron stars. Our members perform theoretical, computational, and observational studies of these extreme physical systems.
Visit the websites of Gravity Initiative Co-Chairs Sam Gralla and Vasileios Paschalidis for more information about current research and publications.

Volume rendering of rest-mass density (color coded) for a circumbinary accretion disk around a binary black hole with spinning black holes. The magnetic field lines (white) are those intersecting the black hole horizons. Twin jets are visible above and below each black hole (see inset for a zoomed-in view). The black spheres indicate the resolved black hole apparent horizons in the simulations. Source: Paschalidis et al. The Astrophysical Journal Letters, 910:L26, 2021
