And while not all seizures cause loss of consciousness, Yale researchers have now discovered how one common type of seizures do. Likewise, recent data from the Dark Energy Spectroscopic Instrument hint at the need for new physics beyond the standard model. Dutra and Natarajan plan to use observed strong lensing by galaxy clusters as astrophysical laboratories to simultaneously probe the nature of dark matter and dark energy. Dutra will compare high-resolution simulations with data to constrain alternatives to cold dark matter. He and Natarajan will also leverage observations to probe the time evolution of dark energy, one of the fundamental open questions in cosmology.
