Dr. Oscar González García with his ESO/IMPRS PhD project,
“Unfolding the Galactic Bulge”
June 25, 2012
Defense was on June 25, 2012 at the Ludwig Maximilians University Munich, Germany, and was graded Magna Cum Laude.
Quoting Marina Rejkuba, his supervisor between 2009 and 2012; “Using the VVV data Oscar investigated extinction and metallicity distribution across the bulge. The high resolution extinction map and the first complete photometric metallicity map of the bulge are available through the BEAM calculator on the web. Furthermore Oscar measured alpha-element abundances in 650 K-type giant stars in 4 bulge fields, confirming, with large number statistics, the chemical similarity between the Galactic bulge and thick disk, which are both alpha-enhanced when compared to the thin disk stars. This study showed that the metal-poor stars show homogeneous alpha-abundance patterns across the bulge, while the metal-rich stars disappear at higher Galactic latitudes.”
He was and one of the first PhD thesis projects using VVV data.
