Luminosity Functions of Gamma-Ray Burst Afterglows

Guðlaugur Jóhannesson, Gunnlaugur Björnsson, Einar H. Gudmundsson

Aims: Use the standard fireball model to create virtual populations of gamma-ray burst afterglows and study their luminosity functions. Methods: We randomly vary the parameters of…

Numerical counterparts of GRB host galaxies

Stephanie Courty, Gunnlaugur Bjornsson, Einar H. Gudmundsson

We explore galaxy properties in general and properties of host galaxies of gamma-ray bursts (GRBs) in particular, using N-body/Eulerian hydrodynamic simulations and the stellar pop…

Extensive multiband study of the X-ray rich GRB 050408. A likely off-axis event with an intense energy injection

A de Ugarte Postigo, T. A. Fatkhullin, G. Johannesson +40

Aims. Understand the shape and implications of the multiband light curve of GRB 050408, an X-ray rich (XRR) burst. Methods. We present a multiband optical light curve, covering the…

GRB 060121: Implications of a Short/Intermediate Duration Gamma-Ray Burst at High Redshift

A. de Ugarte Postigo, A. J. Castro-Tirado, S. Guziy +23

Since the discovery of the first short-hard gamma-ray burst afterglows in 2005, the handful of observed events have been found to be embedded in nearby (z < 1), bright underlying g…

Afterglow Light Curves and Broken Power Laws: A Statistical Study

Gudlaugur Jóhannesson, Gunnlaugur Björnsson, Einar H. Gudmundsson

In gamma-ray burst research it is quite common to fit the afterglow light curves with a broken power law to interpret the data. We apply this method to a computer simulated populat…

The GRB 030329 host: a blue low metallicity subluminous galaxy with intense star formation

J. Gorosabel, D. Pérez-Ramírez, J. Sollerman +13

We present broad band photometry and spectroscopic observations of the host galaxy of GRB 030329. Analysis of the spectral emission lines shows that the host is likely a low metall…
