Galaxy counterparts of metal-rich damped Lyman-alpha absorbers - II. A solar-metallicity and dusty DLA at z_abs=2.58
J. P. U. Fynbo, C. Ledoux, P. Noterdaeme +14
[Abridged]. Here, we report on the discovery of the galaxy counterpart of the z_abs=2.58 DLA on the line-of-sight to the z=3.07 quasar SDSS J091826.16+163609.0. The galaxy counterp…
Discovery of the nearby long, soft GRB 100316D with an associated supernova
R. L. C. Starling, K. Wiersema, A. J. Levan +43
We report the Swift discovery of nearby long, soft gamma-ray burst GRB 100316D, and the subsequent unveiling of its low redshift host galaxy and associated supernova. We derive the…
New limit on a varying proton-to-electron mass ratio from high-resolution optical quasar spectra
Adrian L. Malec, Ruth Buning, Michael T. Murphy +7
Molecular transitions recently discovered at redshift z_abs=2.059 toward the bright background quasar J2123-0050 are analysed to limit cosmological variation in the proton-to-elect…
