We present results on the disk-disk major merger fraction evolution up to z˜1 in SPITZER/IRAC selected samples in the GOODS-S field. We pick as merger remnants...
The merging/AGN connection: a case for 3D spectroscopy
We discuss an ongoing study of the connection between galaxy merging/interaction and AGN activity, based on integral field spectroscopy. We focus on the search...
The Metallicity Distribution and Its Gradients in the LMC via Calcium Triplet Spectroscopy
We present a new calibration of the CaII triplet as metallicity indicator based in 4 globular and 11 open clusters which cover a range of metallicity - 2≤[Fe/H]...
The Metallicity Distribution Function of the Halo of the Milky Way
We report on the distribution of metallicities, [Fe/H], for very metal-poor stars in the halo of the Galaxy. Although the primary information on the nature of...
The Metallicity Distribution of the Milky Way's Stellar Halo
SDSS DR6 includes about 300,000 stellar spectra, and a significant fraction of them belong to members of the halo. We make use of these data to examine closely...
The Metallicity Planet Correlation In The Harps Volume Limited Sample
To understand the formation and evolution of solar-type stars and planets in the solar neighborhood, we need to obtain their stellar parameters with high...
