DESI DR2 data constrain the neutrino mass sum below the inverted hierarchy minimum, yielding Bayes factor K>460 for normal hierarchy in standard cosmology.
Future global 21-cm observations could beat CMB limits on TeV-scale decaying dark matter for lifetimes ≳10^15 s, especially for decays into neutrinos.
Using eclipse attenuation in the LMC X-4 neutron star binary, the authors set g_aγ ≤ 1.44 × 10^{-10} GeV^{-1} at 90% CL, surpassing current light-shining-through-walls bounds.
A mini-review of axion phenomenology showing how light bosons can account for dark matter, drive cosmic acceleration, or contribute to relativistic backgrounds in the early and late Universe.
