Similar star formation rate and metallicity variability time-scales drive the fundamental metallicity relation [PDF]
, 2017 The fundamental metallicity relation (FMR) is a postulated correlation between galaxy stellar mass, star formation rate (SFR), and gas-phase metallicity.

Binary Formation in Star-Forming Clouds with Various Metallicities
, 2008 Cloud evolution for various metallicities is investigated by three-dimensional nested grid simulations, in which the initial ratio of rotational to gravitational energy of the host cloud \beta_0 (=10^-1 - 10^-6) and cloud metallicity Z (=0 - Z_\odot) are

CARBON AND OXYGEN ABUNDANCES IN LOW METALLICITY DWARF GALAXIES [PDF]
, 2016 The study of carbon and oxygen abundances yields information on the time evolution and nucleosynthetic origins of these elements, yet they remain relatively unexplored. At low metallicities, (12+log(O/H) < 8.0), nebular carbon measurements are limited to

An empirical prediction for stellar metallicity distributions in nearby galaxies
, 2012 We combine star-formation histories derived from observations of high redshift galaxies with measurements of the z~0 relation between gas-phase metallicity, stellar mass, and star formation rate to make an explicit and completely empirical connection ...

F stars, metallicity, and the ages of red galaxies at z > 1 [PDF]
, 2001 We explore whether the rest-frame near-UV spectral region, observable in high-redshift galaxies via optical spectroscopy, contains sufficient information to allow the degeneracy between age and metallicity to be lifted.

Galaxy metallicity scaling relations in the EAGLE simulations [PDF]
, 2017 We quantify the correlations between gas-phase and stellar metallicities and global properties of galaxies, such as stellar mass, halo mass, age and gas fraction, in the Evolution and Assembly of GaLaxies and their Environments suite of cosmological ...

Gas metallicity diagnostics in star-forming galaxies
, 2006 Generally the gas metallicity in distant galaxies can only be inferred by using a few prominent emission lines. Various theoretical models have been used to predict the relationship between emission line fluxes and metallicity, suggesting that some line ...

CRITICAL METALLICITY FOR POPULATION II STARS
Odessa Astronomical Publications, 2008 We present simple arguments about metallicity of transition from first stellar generation (population III) to the second one. We consider the efficiency of fragmentation in gas induced by thermal instability in cold gas layers and filaments (T < 104 K ...

Exploring the host environments of long-duration gamma-ray bursts
, 2011 We have conducted the first dedicated spectroscopic survey of long-duration gamma-ray burst (LGRB) host galaxies at z < 1, and use these observations along with data from the literature to determine a wide range of ISM properties and a statistically ...
