Galactic Astronomy 銀河物理学特論 I Lecture 3-4: Chemical evolution of galaxies Seminar: Erb et al. 2006, ApJ, 644, 813 Lecture: 2012/01/23

Gas consumption and rise of metallicities of galaxies: Erb. 2008, ApJ, 674, 151

Mass-metallicity relation of z~3 LBGs: Metallicity estimation with using various lines in parallel. Maiolino et al. 2008, A&A,488, 463

Mass-metallicity relation of z~3 LBGs: Redshift evolution of the mass-metallicity relation of galaxies. At higher redshifts, the measured metallicity is lower for the galaxies with same stellar mass. At higher redshift, the relation is derived only using blue star-forming galaxies… Maiolino et al. 2008, A&A, 488, 463

FMOS observation of Mass-metallicity relation of z~1.4 galaxies: Determination of the “intrinsic” scatter of the mass-metallicity relation, and examination of the “2ry” parameter. Maiolino et al. 2008, A&A, 488, 463 Yabe et al. arXiv1112.3704

FMOS observation of Mass-metallicity relation of z~1.4 galaxies: Determination of the “intrinsic” scatter of the mass-metallicity relation, and examination of the “2ry” parameter which determines the “intrinsic” scatter of the relation. Yabe et al. arXiv1112.3704

Metallicity of other systems: Metal abundances of damped-Lya galaxies: Metallicity of Damped Lya system determined with metallic absorption lines. Z=2.8110 system Fe, Si, Zn, Ni, S, Mg, Cr, C, N, O Z=4.0803 system Fe, C, Si, Al, Ni Z=0.8598 system Fe, Mn, Zn, Cr, Mg Lu et al. 1996, ApJS, 107, 475

Metallicity of other systems: Metal abundances of damped-Lya galaxies: Fe/H is smaller compared with the galactic disk stars formed at that redshift. Abundance ratio is similar to halo stars in the Galaxy, which suggests contribution from Type-II Sne is large, contribution from Type-Ia SNe is small. ? Lu et al. 1996, ApJS, 107, 475

Metal abundances of Gamma-ray Burst Absorption systems: GRB に見られた DLA に付随する金属吸収線を用いてそれぞれの金属の組成量を推定する。 Prochaska et al. 2007, ApJ, 666, 267
