The GROND GRB sample: II. Fireball parameters for four GRB afterglows

Karla Varela, Jochen Greiner, Patricia Schady +1

Afterglows of GRBs are, in general, well described by the fireball model. Yet, deducing the full set of model parameters from observations without prior assumptions has been possib…

Gamma-ray Emission of 60Fe and 26Al Radioactivities in our Galaxy

W. Wang, T. Siegert, Z. G. Dai +7

The isotopes Fe and Al originate from massive stars and their supernovae, reflecting ongoing nucleosynthesis in the Galaxy. We studied the gamma-ray emission from the…

Improved Fermi-GBM GRB localizations using BALROG

F. Berlato, J. Greiner, J. Michael Burgess

The localizations of gamma-ray bursts (GRBs) detected with the Gamma-ray Burst Monitor (GBM) onboard the Fermi satellite are known to be affected by significant systematic errors o…

Gamma-ray bursts as cool synchrotron sources

J. Michael Burgess, Damien Bégué, Ana Bacelj +3

Gamma-ray bursts are the most energetic electromagnetic sources in the Universe. Their prompt gamma-ray radiation corresponds to an energy release of 1E42-1E47J. Fifty years after…

X-shooter and ALMA spectroscopy of GRB 161023A - A study of metals and molecules in the line of sight towards a luminous GRB

A. de Ugarte Postigo, C. C. Thöne, J. Bolmer +45

Long gamma-ray bursts are produced during the dramatic deaths of massive stars with very short lifetimes, meaning that they explode close to the birth place of their progenitors. D…

The peculiar physics of GRB 170817A and their implications for short GRBs

D. Bégué, J. Michael Burgess, J. Greiner

The unexpected nearby gamma-ray burst GRB 170817A associated with the LIGO binary neutron star merger event GW170817 presents a challenge to the current understanding of the emissi…
