TL;DR: In this paper, the most widely used empirical oxygen calibrations, O3N2 and N2, by using new direct abundance measurements are reviewed, and the expected uncertainty of these calibrations as a function of the index value or abundance derived is analyzed.

De re metallica: the cosmic chemical evolution of galaxies
TL;DR: In this paper, the authors provide an overview of the methods used to constrain the chemical enrichment in galaxies and their environment, and discuss the observed scaling relations between metallicity and galaxy properties, the observed relative chemical abundances, how the chemical elements are distributed within galaxies, and how these properties evolve across the cosmic epochs.

The star formation history and metal content of the green peas. new detailed gtc-osiris spectrophotometry of three galaxies
TL;DR: In this paper, the authors present deep broadband imaging and long-slit spectroscopy of three compact, low-mass starburst galaxies at redshift z ~ 0.2-0.3, referred to as Green Peas (GP).

The relationship between infrared, optical, and ultraviolet extinction
TL;DR: In this article, the average extinction law over the 3.5 micron to 0.125 wavelength range was derived for both diffuse and dense regions of the interstellar medium. And the validity of the law over a large wavelength interval suggests that the processes which modify the sizes and compositions of grains are stochastic in nature.

Classification parameters for the emission-line spectra of extragalactic objects
TL;DR: In this paper, the merits of various emission-line intensity ratios for classifying the spectra of extragalactic objects were investigated and it was shown empirically that several combinations of easily-measured lines can be used to separate objects into one of four categories according to the principal excitation mechanism: normal H II regions, planetary nebulae, objects photoionized by a power-law continuum, and objects excited by shock-wave heating.

On the Kolmogorov-Smirnov Test for Normality with Mean and Variance Unknown
TL;DR: In this paper, the power of the Kolmogorov-smirnov test is investigated and a table for testing whether a set of observations is from a normal population when the mean and variance are not specified but must be estimated from the sample.

Theoretical Modeling of Starburst Galaxies
TL;DR: In this paper, a large sample of infrared starburst galaxies using both the PEGASE v2.0 and STARBURST99 codes was used to generate the spectral energy distribution (SED) of the young star clusters.

TL;DR: In this paper, the authors used Monte Carlo realizations of different star formation histories, including starbursts of varying strength and a range of metallicities, to constrain the mean stellar ages of galaxies and the fractional stellar mass formed in bursts over the past few Gyr.
