Theoretical physicists have generalized the classic 1968 cube of spacetime symmetry algebras using semigroup expansions, yielding an infinite hierarchy of...

A new two-dimensional dynamical model shows that the rotation speed and magnetic field strength of filamentary molecular clouds determine whether...

A new analytical study provides the first closed-form description of how magnetic helicity is created during time-dependent separator reconnection in...

A new quantitative application of non-isothermal sound generation theory to the Sun's convection zone shows that temperature gradients leave total...

A new global analysis shows that forest fragmentation raises land surface temperatures across most forest biomes, often mattering more for...

A new theoretical study shows that Einstein–Euler–Heisenberg black holes spontaneously grow scalar hair in two distinct regimes, with the sign...

A Bayesian marginalization technique promises sharper, more reliable ground-based solar images with far less manual tuning.

A new teleparallel gravity analysis uses cosmic textures, strings, and LIGO gravitational-wave data to bound spacetime torsion below ten to...

New simulations show that a reflective surface near a black hole's horizon would imprint delayed electromagnetic echoes in the light...

A new theoretical study of multi-horizon black holes in nonlinear electrodynamics shows that classically forbidden regions can bounce infalling particles...
