A tale of two pulses: Observational evidence for two distinct polarized emission sites in gamma-ray burst outflow

Gamma-ray bursts (GRBs) are the brightest explosions in the universe. In just a few seconds, they can outshine all the stars in their host galaxy combined, releasing more energy than our sun will emit over its entire lifetime. ...

Plasmon effects in neutron star magnetospheres could pose new limits on the detection of axions

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is predicted to account for most of the universe's mass. As it cannot be detected and studied using conventional experimental techniques, ...

18-member nanoring pushes the boundaries of global aromaticity

Pushing the limits of size constraints in chemistry, an 8-nanometer 18-porphyrin nanoring (c-P18) becomes the largest known cyclic molecule to exhibit detectable global aromaticity. This phenomenon, where π-electrons are ...
