Outliers from the Mass–Metallicity Relation I: A Sample of Metal-Rich Dwarf Galaxies from SDSS
We have identified a sample of 41 low-mass high–oxygen abundance outliers from the mass–metallicity relation of star-forming galaxies measured by Tremonti et al. (2004). These galaxies, which have 8.6 < 12 + log(O/H) < 9.3 over a range of −14.4 > MB > −19.1 and 7.4 < log(M⋆/M⊙) < 10, are surprisingly non-pathological. They have typical specific star formation rates, they are fairly isolated and...
متن کاملOutliers from the Mass–metallicity Relation Ii: a Sample of Massive Metal-poor Galaxies from Sdss
We present a sample of 42 high-mass low-metallicity outliers from the mass–metallicity relation of star-forming galaxies. These galaxies have stellar masses that span log(M⋆/M⊙) ∼ 9.4 to 11.1 and are offset from the mass–metallicity relation by −0.3 to −0.85dex in 12+ log(O/H). In general, they are extremely blue, have high star formation rates for their masses, and are morphologically disturbe...
متن کاملGalaxy merging , the Fundamental Plane of elliptical galaxies , and the M BH - σ 0 relation
We explore the effects of dissipationless merging on the Fundamental Plane of elliptical galaxies by using a N-body code based on a new, high performance numerical scheme (Dehnen 2002). We investigate the two extreme cases of galaxy growth by equal mass merging and accretion of small stellar systems; in a subset of simulations we also consider the presence of dark matter halos around the mergin...
متن کاملThe Physical Relation between Age and Metallicity in Galaxies
We present unified chemical and spectrophotometric evolutionary synthesis models that allow to describe composite stellar populations in a chemically consistent way. Keeping track of the ISM abundance at birth of each star and using sets of input physics (stellar yields, tracks, spectra) for different metallicities we account for the increasing initial metallicity of successive stellar generati...
متن کاملThe Universal Stellar Mass–stellar Metallicity Relation for Dwarf Galaxies
We present spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular galaxies (dIrrs), and we show that dIrrs obey the same mass–metallicity relation as the dwarf spheroidal (dSph) satellites of both the Milky Way and M31: Z∗ ∝ M 0.30±0.02 ∗ . The uniformity of the relation is in contradiction to previous estimates of metallicity based on photometry. This relationship is...
