White dwarf mass-radius data exclude large parameter space for ultralight scalars quadratically coupled to fermions by predicting forbidden radius gaps and mass shifts toward the Chandrasekhar limit or altered maximum masses.
Incorporating timing information from time-dependent new physics signals can improve LHC search sensitivity by up to a factor of two compared to standard time-invariant analyses.
Self-interaction bounds from cosmology constrain ultralight dark matter couplings to neutrinos, electrons, and light quarks via unavoidable quantum loop corrections.
