The nearby GRB 060216/SN 2006aj was an extremely long, weak and very soft GRB. It was peculiar in many aspects. We show here that the x-ray, ultraviolet/optical and radio afterglows of GRB 060218 have to be attributed to different physical processes arising from different emission regions. From the several components in this burst's afterglow only the radio afterglow can be interpreted in terms of the common external shock model. We infer from the radio that the blast wave's kinetic energy was… Expand

The afterglow of a relativistic shock breakout and low-luminosity GRBs
The prompt emission of low-luminosity gamma-ray bursts (llGRBs) indicates that these events originate from a relativistic shock breakout. In this case we can estimate, based on the properties of theExpand
GRB 060218: A Relativistic Supernova Shock Breakout
We show that the prompt and afterglow X-ray emission of GRB 060218, as well as its early (t 1 day) optical-UV emission, can be explained by a model in which a radiation-mediated shock propagatesExpand
GRB 060418 and 060607A: the medium surrounding the progenitor and the weak reverse shock emission
We constrain the circumburst medium profile with the rise behaviour of the very early afterglow light curves of gamma-ray bursts (GRBs). Using this method, we find a constant and low-density mediumExpand
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
The observations of gamma-ray bursts (GRBs) such as 980425, 031203 and 060218, with luminosities much lower than those of other classic bursts, lead to the definition of a new class of GRBs—LL-GRBs.Expand
Two types of softening detected in x-ray afterglows of Swift bursts: internal and external shock origins?
The softening process observed in the steep decay phase of early x-ray afterglows of Swift bursts has remained a puzzle since its discovery. The softening process can also be observed in the laterExpand
Puzzled by GRB 060218
We study the optical‐UV/X‐ray spectral energy distribution of GRB 060218 during the prompt phase and during what seems to be the afterglow phase. The results are puzzling, since if the opt‐UV and theExpand
Sw 1644+57/GRB 110328A is a remarkable cosmological X-ray outburst detected by the Swift satellite. Its early-time (t less than or similar to 0.1 days since the trigger) X-ray emission resembles someExpand
GRB 090618: Detection of thermal X-ray emission from a bright gamma-ray burst
A thorough analysis of the prompt and early afterglow emission of GRB 090618 using data from Swift, Fermi Gamma-ray Burst Monitor and ROTSE finds evidence of a thermal X-ray component alongside the expected non-thermal power-law continuum. Expand
GRB 060218 and GRBs associated with supernovae Ib/c
Context. The Swift satellite has given continuous data in the range 0.3–150 keV from 0 s to 10 6 s for GRB 060218 associated with SN2006aj. This Gamma-Ray Burst (GRB) which has an unusually longExpand


The association of GRB 060218 with a supernova and the evolution of the shock wave
A supernova is caught in the act of exploding, directly observing the shock break-out, which indicates that the GRB progenitor was a Wolf–Rayet star. Expand
The Rapidly Fading Optical Afterglow of GRB 980519
GRB 980519 had the most rapidly fading of the well-documented gamma-ray burst (GRB) afterglows, consistent with t in BVRI as well as in X-rays during the 2 days in which observations were made. WeExpand
Radio supernova sn 1998bw and its relation to grb 980425
SN 1998bw is an unusual Type Ic supernova that may be associated with the γ-ray burst GRB 980425. We use a synchrotron self-absorption model for its radio emission to deduce that theExpand
Supernova 2006aj and the associated X-Ray Flash 060218
Aims. We have studied the afterglow of the gamma-ray burst (GRB) of February 18, 2006. This is a nearby long GRB, with a very low peak energy, and is therefore classified as an X-ray Flash (XRF). XRFExpand
Thick Fireballs and the Steep Decay in the Early X-Ray Afterglow of Gamma-Ray Bursts
We study the early afterglows of gamma-ray bursts produced by geometrically thick fireballs, following the development of the external shock as energy is continually supplied to the shocked material.Expand
Diverse Temporal Properties of Gamma-Ray Burst Afterglows
The detection of delayed X-ray, optical, and radio emission, the "afterglow" associated with gamma-ray bursts (GRBs), is consistent with fireball models, in which the emission is produced by aExpand

Gamma-ray bursts and the fireball model
Abstract Gamma-ray bursts (GRBs) have puzzled astronomers since their accidental discovery in the late 1960s. The BATSE detector on the COMPTON-GRO satellite has been detecting one burst per day forExpand
