Evolution of the polarization of the optical afterglow of the gamma-ray burst GRB 030329
J. Greiner, S. Klose, K. Reinsch +23
We report 31 polarimetric observations of the afterglow of GRB 030329 with high signal-to-noise and high sampling frequency. We establish the polarization light curve, detect susta…
Line shape diagnostics of Galactic 26Al
K. Kretschmer, R. Diehl, D. H. Hartmann
The shape of the gamma-ray line from radioactive 26Al, at 1808.7 keV energy in the frame of the decaying isotope, is determined by its kinematics when it decays, typically 10^6 y a…
Implications of Cosmological Gamma-Ray Absorption II. Modification of gamma-ray spectra
T. M. Kneiske, T. Bretz, K. Mannheim +1
Bearing on the model for the time-dependent metagalactic radiation field developed in the first paper of this series, we compute the gamma-ray attenuation due to pair production in…
Constraining the Cosmic Star Formation Rate with the MeV Background
K. Watanabe, D. H. Hartmann, M. D. Leising +1
The Cosmic Gamma-ray Background (CGB) in the MeV regime has been measured with COMPTEL and SMM. The origin of the CGB in this energy regime is believed to be dominated by gamma-ray…
