Giant star explosion casts light on distant galaxies

An international team of astronomers including members from the Niels Bohr Institute have used a short but intense light from a distant gamma-ray burst to investigate the composition of matter in very distant galaxies. Surprisingly, it turns out that some galaxies in the early universe were richer in elements than our Sun. The observations have been published in the scientific magazine, Monthly Notices of the Royal Astronomical Society.

Title: GRB 090323 and GRB 090328: two long high-energy GRBs detected with Fermi
Authors: Elisabetta Bissaldi, for the Fermi GBM Collaboration

We present the analysis of two long Gamma-Ray Bursts, GRB 090323 and GRB 090328, which triggered the Fermi Gamma-Ray Burst Monitor (GBM) and generated an Autonomous Repoint Request to the Fermi Large Area Telescope. The GBM light curves show multi-peaked structures for both events. Here, we present time-integrated and time-resolved burst spectra fitted with different models by the GBM detectors.
