TL;DR: In this article, the authors used a prior based on the Two Degree Field (2dF) Redshift Survey constraint on ΩM and assuming a flat universe, they found that the equation of state parameter of the dark energy lies in the range -1.48 -1, and obtained w < -0.73 at 95% confidence.

Lee,Nimish P. Hathi,Rolf A. Jansen,Rogier A. Windhorst,L. Echevarria,Daniel J. Eisenstein,Bartosz Pindor,Edward W. Olszewski,Paul Harding,Stephen T. Holland,D. Bersier +21 more
TL;DR: In this article, the authors present early observations of the afterglow of GRB 030329 and the spectroscopic discovery of its associated supernova SN 2003dh, showing that the early spectra consist of a power-law continuum (Fν ν-0.9) with narrow emission lines originating from H II regions in the host galaxy.
