Along the first millennium BCE and up to the beginning of the Roman conquest at the end of III century BCE, the southeast part of the Iberian Peninsula was colonized by Phoenicians, Greeks and Punics. All these cultures influenced the religious and funereal world of the indigenous peoples. Tartessians and Iberians were the main Protohistoric

The Canary island of La Palma (ancient Benahoare) is one the richest island territory of the world in rock art manifestations (Martín Rodríguez and Pais Pais, 1996); there are dozens of petroglyph stations in a territory of only 700 km2 . These groups of petroglyphs, carved in a delicate way by picking or lining techniques, often are

Since its first observational evidence, gravitational lensing - the deflection of light by mass - has become an established astrophysical tool than can be used to study the physical properties and environments of the lens galaxies and to reveal the structure of the lensed quasars. This thesis combines theoretical and observational results of a

Data from the SDSS-IV/Apache Point Observatory Galactic Evolution Experiment (APOGEE-2) have been released as part of SDSS Data Releases 13 (DR13) and 14 (DR14). These include high-resolution H-band spectra, radial velocities, and derived stellar parameters and abundances. DR13, released in 2016 August, contained APOGEE data for roughly 150,000

The data and analysis methodology used for the SDSS/APOGEE Data Releases 13 and 14 are described, highlighting differences from the DR12 analysis presented in Holtzman et al. Some improvement in the handling of telluric absorption and persistence is demonstrated. The derivation and calibration of stellar parameters, chemical abundances, and
