ZF-UDS-7329: A relic galaxy in the early Universe
Eduardo A. Hartmann, Ignacio MartÃn-Navarro, Marc Huertas-Company +4
The formation time scales of quiescent galaxies can be estimated in two different ways: by their star formation history and by their chemistry. Previously, the methods yielded conf…
