We present the values of CN and Mg overabundances with respect to Fe, for a large sample of elliptical galaxies in different environments. Abundances were...
We present a study of C, N, and O abundances for 24 unevolved metalpoor stars with metallicities in the range -0.3 [Fe/H] -3. New C and N abundances have been...
Co-Evolution of Supermassive Black Holes and Their Host Galaxies
We study the evolution of the MBH/Mhost relation up to z = 3 for a sample of 96 quasars with known host galaxy luminosities. Black hole masses are estimated...
