A new theoretical study shows that a Hernquist dark matter halo and a black hole's magnetic charge leave competing, potentially ...

New calculations show that boson stars combining ground-state and excited-state scalar fields undergo a sudden sign flip in their tidal ...

Theoretical physicists have constructed a consistent effective spacetime metric for bound binary systems at third post-Minkowskian order, improving the analytical ...
