Journal ArticleDOI
Metallicity Calibrations and the Mass-Metallicity Relation for Star-forming Galaxies
Lisa J. Kewley,Sara L. Ellison +1 more
TL;DR: In this article, the effect of metallicity calibrations, AGN classification, and aperture covering fraction on the local mass-metallicity relation using 27,730 star-forming galaxies from the Sloan Digital Sky Survey (SDSS) Data Release 4.
Journal ArticleDOI
A catalog of bulge+disk decompositions and updated photometry for 1.12 million galaxies in the sloan digital sky survey
TL;DR: In this paper, the authors performed two-dimensional, point-spread-function-convolved, bulge+disk decompositions in the g and r bandpasses on a sample of 1,123,718 galaxies from the Legacy area of the Sloan Digital Sky Survey Data Release Seven.

TL;DR: The data, combined with radio and X-ray observations, suggest that XRF 060218 is an intrinsically weak and soft event, rather than a classical GRB observed off-axis, which extends the GRB–supernova connection to X-rays flashes and fainter supernovae, implying a common origin.
Journal ArticleDOI
New constraints on the free-streaming of warm dark matter from intermediate and small scale Lyman-α forest data

TL;DR: In this paper, the free-streaming of warm dark matter (WDM) from Lyman-α flux-power spectra was studied using hydrodynamical simulations.
Journal ArticleDOI
Galaxy pairs in the sloan digital sky survey. i. star formation, active galactic nucleus fraction, and the luminosity/mass-metallicity relation
TL;DR: In this article, a sample of 1716 galaxies with companions within Δv <500 km s−1, rp < 80 h−1 70 kpc and stellar mass ratio 0.1 < M 1/M 2 < 10 from the Sloan Digital Sky Survey Data Release 4.
