    A Strong Stellar Age─Metallicity Gradient Relation in Nearby Dwarf Galaxies Driven by Stellar Migration and Environmental Quenching
    Stellar metallicity gradients (∇[Z/H]) provide a fossil record of the assembly history of galaxies. We present an analysis of ∇[Z/H] for 90 nearby low-mass...

    New Clues on the Extended He II Ionization in IZw18 from GTC/MEGARA and JWST/MIRI
    IZw18 is one of the lowest-metallicity star-forming galaxies known at z ∼ 0, considered a unique local analogue of the first galaxies. The origin of its hard...
