This is an exciting time for stellar astrophysics as high-cadence time domain surveys (Gaia, PTF, ZTF, ATLAS, Kepler, TESS, and, in the near future, the Vera Rubin Observatory) are revolutionizing the landscape of stellar studies by allowing the...

The cosmic microwave background is a sensitive probe of early-Universe physics, and yet fundamental constants at recombination can differ from their present day values due to degeneracies in the standard cosmological model. Such scenarios have been...
