Context: The origin of X-ray Flashes (XRFs) is still a mystery and several models have been proposed. To disentangle among these models, an important observational tool is the measure of the XRF distance scale, so far available only for a few of them. Aims: In this work, we present a multi-wavelength study of XRF 040912, aimed at measuring its distance scale and the intrinsic burst properties. Methods: We performed a detailed spectral and temporal analysis of both the prompt and the afterglow… Expand

The INTEGRAL view of Gamma-Ray Bursts
After more than six and half years in orbit, the ESA space observatory INTEGRAL has provided new, exciting results in the soft gamma-ray energy range (from a few keV to a few MeV). With the discoveryExpand
A COMPARISON OF THE AFTERGLOWS OF SHORT- AND LONG-DURATION GAMMA-RAY BURSTS
We present a comparative study of the observed properties of the optical and X-ray afterglows of short- and long-duration {gamma}-ray bursts (GRBs). Using a large sample of 37 short and 421 longExpand
Low-Luminosity GRB 060218: A Collapsar Jet from a Neutron Star, Leaving a Magnetar as a Remnant?
The gamma-ray burst (GRB) 060218 has a luminosity ~105 times lower than that of typical long GRBs and is associated with a supernova (SN). The radio afterglow displays no jet break, so this burstExpand
Intrinsic properties of a complete sample of HETE-2 Gamma-ray bursts A measure of the GRB rate in the Local Universe
Aims: Taking advantage of the forthcoming Catalog of the HETE-2 mission, the aim of this paper is to evaluate the main properties of HETE-2 GRBs - the E_peak, the T_90 and the E_iso - in their sourceExpand
A complete catalog of Swift gamma-ray burst spectra and durations: Demise of a physical origin for pre-Swift high-energy correlations
We calculate durations and spectral parameters for 218 Swift bursts detected by the BAT instrument between and including gamma-ray bursts (GRBs) 041220 and 070509, including 77 events with measuredExpand
A Comparative Study of Long and Short GRBs. I. Overlapping Properties
Gamma ray bursts (GRBs) are classified into long and short categories based on their durations. Broad band studies suggest that these two categories of objects roughly correspond to two differentExpand
Measuring the cosmological parameters with the Ep,i–Eiso correlation of gamma-ray bursts
We have used the E p,i -E iso correlation of gamma-ray bursts (GRBs) to measure the cosmological parameter Ω M . By adopting a maximum likelihood approach which allows us to correctly quantify theExpand
Statistical classification of gamma-ray bursts based on the Amati relation
Gamma-ray bursts (GRBs) are believed to belong to two classes and they are conventionally divided according to their durations. This classification scheme is not satisfied due to the fact thatExpand

Evidence for a Supernova Associated with the X-Ray Flash 020903*
TLDR
Ground-based and Hubble Space Telescope optical observations of the X-ray flash (XRF) 020903 show a very rapid rise in the first day, followed by a relatively slow decay in the next few days, which argues in favor of the existence of a SN associated with this XRF. Expand
