A World That Refuses to Shine: JWST Reveals a Planet’s Blank Face
JWST’s mid-infrared spectrum of LHS 3844 b reveals a dark, space-weathered basaltic surface and no detectable atmosphere.
A Bar Born Where None Should Be
A stellar bar, over 7 kiloparsecs long, is revealed in the gas-rich galaxy GN20 just 1.5 billion years after the Big Bang, challenging theories of bar formation.
Fluid Dynamics Learns to Intersect: A Geometric Reformulation
Fluid dynamics is revealed as the intersection of a coisotropic submanifold (spacetime constraints) and a Lagrangian submanifold (fluid equation of state) in an infinite-dimensional symplectic geometry.
The Imaginary Distance Bound: When Wormholes Draw a Line
Wormholes in quantum gravity impose an imaginary distance bound, limiting how far a theory's parameters can be twisted before consistency breaks down.
A Ghost in the Machine: Can Rydberg Atoms Sniff Out Dark Photons?
A tabletop array of laser-trapped Rydberg atoms could serve as a receiver for the faint electric fields of dark photons.
The Ghost in the Bridge: When Wormholes Learned to Speak Quantum
In the ER=EPR conjecture, the wormhole connecting two black holes is the geometric expression of their quantum entanglement.
Did a Black Hole's Invisible Cloud Just Whisper?
A faint cloud of ultralight scalar particles around a black hole binary may have left a subtle imprint in gravitational waves, hinting at dark matter.
When a Black Hole’s Disk Refuses to Shine
A self-gravitating disk around a quiet black hole glows red at 4000 kelvin, its star-embedded outer layers shining while the inner region stays dark. This disk Hayashi limit explains the Little Red Dots.
Still Accelerating: How Supernovae Withstand a Progenitor Age Challenge
Type Ia supernovae remain robust standard candles for cosmology, withstanding challenges from host galaxy age evolution.
When Nuclei Tell Time: A New Way to Calculate Beta-Decay Lifetimes
A first-principles calculation of beta-decay lifetimes for neutron-rich N=50 nuclei provides a self-consistent clock for the r-process element formation.
Ion Trap Revealing Missing Pathway for Space’s Nitrogenated PAHs
Ion trap experiments reveal a barrier-less gas-phase reaction between pyrimidine cations and acetylene, forming an endocyclic nitrogenated PAH under interstellar conditions.
When a SQUID Hunts Axions by Squaring the Field
A dc SQUID operated at its flux sweet spot detects the zero-frequency component of the squared axion field, enabling a broadband search for dark matter across a vast mass range.
