    • Mg2 gradients as a signature of brightest cluster galaxy evolution 

      Loubser, S.I.; Sánchez-Blázquez, P. (Wiley, 2011)
      We have fitted the Mg2 absorption index gradients for 21 brightest cluster galaxies (BCGs), in the nearby Universe, for which we have obtained high signal-to-noise ratio, long-slit spectra on the Gemini telescopes. This ...
