A 62-day underground experiment found no radiation signature predicted by a generalized Károlyházy model, constraining one prominent proposal for gravity-induced ...

Theoretical calculations show that lightweight interstellar probes could probe departures from general relativity by circling a black hole during near-critical ...

A theoretical analysis reconstructs generalized black-hole horizon entropy from a modified curvature Lagrangian within spherically symmetric vacuum solutions.

A single-galaxy X-ray and radio study links a truncated accretion disk and hot plasma flow with relativistic jet launching in ...

A theoretical analysis finds that lightweight probes orbiting close to a stellar-mass black hole could detect subtle departures from general ...

A new theoretical analysis shows that unimodular gravity and general relativity produce identical wormhole geometries and geodesics, while demanding fundamentally ...

Bixano and Matos extend the Ernst potential formalism to Einstein-Maxwell gravity coupled to dilatonic or phantom scalar fields, deriving a ...

The distinction between gravitationally bound and unbound configurations sits at the heart of the new results. In Newtonian terms, a ...

A new theoretical analysis shows that quantum effects begin to strongly oppose gravitational collapse exactly at a discontinuous transition called ...

Researchers have constructed an exact rotating dilatonic black hole solution of Einstein–ModMax gravity that admits no Maxwell counterpart, with a ...
