We present the most extensive and complete study of the properties for the largest sample
(46 objects) of gamma-ray burst (GRB) host galaxies. The redshift interval and the mean …

We present multiwavelength observations of the afterglow of GRB 130427A, the brightest (in
total fluence) gamma-ray burst (GRB) of the past 29 yr. Optical spectroscopy from Gemini …

We have used the E p, i–E iso correlation of gamma-ray bursts (GRBs) to measure the
cosmological parameter ΩM. By adopting a maximum likelihood approach which allows us …

We have gathered optical photometry data from the literature on a large sample of Swift-era
gamma-ray burst (GRB) afterglows including GRBs up to 2009 September, for a total of 76 …

We present a systematic temporal and spectral study of all Swift-X-ray Telescope
observations of gamma-ray burst (GRB) afterglows discovered between 2005 January and …

Since the launch of the highly successful and ongoing Swift mission, the field of gamma-ray
bursts (GRBs) has undergone a revolution. The arcsecond GRB localizations available …

We present optical and near-infrared photometry of the afterglow of the long gamma-ray
burst (GRB) 070802 at redshift 2.45 obtained with the ESO/MPI 2.2 m telescope equipped …

Knowledge of the bulk Lorentz factor Γ 0 of gamma-ray bursts (GRBs) allows us to compute
their comoving frame properties shedding light on their physics. Upon collisions with the …

In this work, we present the first results of our imaging campaign at Keck Observatory to
identify the host galaxies of" dark" gamma-ray bursts (GRBs), events with no detected optical …
