• Stellar Proper Motions in the Galactic Bulge from Deep Hubble Space Telescope ACS WFC Photometry (2008, background): “…rapid enrichment; Type II supernovae (SNe) produce the -elements and result from short-lived, high-mass stars, while iron enrichment requires the rather slower buildup of a significant number of Type I SNe (McWilliam&Rich1994; Zoccali et al. 2006; Lecureur et al. 2007; Fulbright et al. 2007).”
• The metal content of bulge field stars from FLAMES-GIRAFFE spectra - I. Stellar parameters and iron abundances (2008, methodology): “The results of bulge stars observations of 50 K giants obtained with UVES withR ≃ 45, 000 have been reported by Zoccali et al. (2006) concerning the oxygen abundance and the [O/Fe] vs. [Fe/H] correlation, and by Lecureur et al. (2007) concerning the abundance of O, Na, Mg, and Al.”
• THE ASSEMBLY OF MILKY-WAY-LIKE GALAXIES SINCE z ∼ 2.5 (2013, background): “The morphology and stellar populations of many spiral galaxies suggest a two-phase scenario, with bulges typically forming at high redshift and disks gradually assembling around them (e.g., Kauffmann, White, & Guiderdoni 1993; Zoccali et al. 2006).”
• Bulge Formation by the Coalescence of Giant Clumps in Primordial Disk Galaxies (2008, background): “Early-type galaxies tend to have ‘‘classical’’ bulges that are red, old, and high in /Fe ratio (indicative of rapid formation), and an n > 2:5 Sersic profile (Zoccali et al. 2006; Ballero et al. 2007; McWilliam et al. 2008; Lecureur et al. 2007).”
• Chemodynamics of the Milky Way - I. The first year of APOGEE data (2013, result): “These preliminary results, while in agreement with earlier studies by, e.g., Zoccali et al. (2006), Fulbright et al. (2007) and Lecureur et al. (2007), are somewhat different from the more recent homogeneous abundance analyses of Meléndez et al. (2008), Alves-Brito et al. (2010)20 and Gonzalez et…”
• The metallicity distribution of bulge clump giants in Baade’s window (2011, methodology): “…of a limited number of stars (10 to 20) in Baade’s window (McWilliam & Rich 1994; Fulbright et al. 2006, 2007), and more recently by our group (Zoccali et al. 2006; Lecureur et al. 2007) in a larger sample of 50 stars in four windows of the Galactic bulge, showed enhanced [α/Fe], compatible…”
• Insights on the Milky Way bulge formation from the correlations between kinematics and metallicity (2010, background): “On the other hand, from medium and high-resolution spectroscopic data enhancements of α elements have been observed (McWilliam & Rich 1994; Zoccali et al. 2006; Fulbright et al. 2007; Lecureur et al. 2007) suggesting a short formation time-scale.”
• Chemical Similarities Between Galactic Bulge And Local Thick Disk Red Giant Stars (2008, background): “In contrast to previous works on the topic (Zoccali et al. 2006; Fulbright et al. 2007; Lecureur et al. 2007), we find that the two populations are indistinguishable in their abundance patterns for the elements considered (C, N and O) up to [Fe/H] = −0.2, i.e. to the metallicity range where the…”
• Alpha element abundances and gradients in the Milky Way bulge from FLAMES-GIRAFFE spectra of 650 K giants (2011, background): “…2010, and references therein) and that the formation of the bulge was fast as evidenced by the enhanced alpha elements in bulge stars (McWilliam & Rich 1994; Rich & Origlia 2005; Zoccali et al. 2006; Fulbright et al. 2006, 2007; Lecureur et al. 2007; Meléndez et al. 2008; Ryde et al. 2009, 2010).”
• Chemical similarities between Galactic bulge and local thick disk red giants: O, Na, Mg, Al, Si, Ca, and Ti (2010, background): “This is in contrast to some previous works on the topic (Zoccali et al. 2006; Fulbright et al. 2007; Lecureur et al. 2007), which argue that [O/Fe] in the bulge is higher than in the thick disk based on a comparison to disk dwarf stars.”
