Over the six years since the discovery of the γ-ray burst GRB 980425, which was associated with the nearby (distance ∼40 Mpc) supernova 1998bw, astronomers have debated fiercely the nature of this event. Relative to bursts located at cosmological distance (redshift z ≈ 1), GRB 980425 was under-luminous in γ-rays by three orders of magnitude. Radio calorimetry showed that the explosion was sub-energetic by a factor of 10. Here we report observations of the radio and X-ray afterglow of the recent…
The second-closest gamma-ray burst: sub-luminous GRB 111005A with no supernova in a super-solar metallicity environment

We report the detection of the radio afterglow of a long gamma-ray burst (GRB) 111005A at 5-345 GHz, including very long baseline interferometry observations with a positional error of 0.2 mas. The
Simulating a faint gamma-ray burst population
There have now been three supernova-associated gamma-ray bursts (GRBs) at redshift z < 0.17, namely 980425, 030329 and 031203, but the nearby and under-luminous GRBs 980425 and 031203 are distinctly

Much of the progress in understanding γ-ray bursts (GRBs) has come from studies of distant events (redshift z ≈ 1). In the brightest GRBs, the γ-rays are so highly collimated that the events can be
Could the GRB-supernovae GRB031203 and XRF060218 be cosmic twins?
• Physics
• 2009
The gamma-ray burst (GRB) / X-ray flash (XRF) events GRB031203, discovered by INTEGRAL, and XRF060218, discovered by Swift, represent two of only five GRB-SNe with optical spectroscopic confirmation
AFTERGLOW OBSERVATIONS OF FERMI LARGE AREA TELESCOPE GAMMA-RAY BURSTS AND THE EMERGING CLASS OF HYPER-ENERGETIC EVENTS
• Physics
• 2010
We present broadband (radio, optical, and X-ray) light curves and spectra of the afterglows of four long-duration gamma-ray bursts (GRBs; GRBs 090323, 090328, 090902B, and 090926A) detected by the
Massive star-formation rates of γ-ray burst host galaxies: An unobscured view in X-rays
• Physics
• 2004
The hard X-ray (2-10 keV) luminosity of a star-forming galaxy tracks its population of high mass X-ray binaries and is essentially unobscured. It is therefore a practically unbiased measure of
The soft X-ray blast in the apparently subluminous GRB 031203
• Physics
• 2005
The difference between the soft and hard X-ray spectra from XMM-Newton and INTEGRAL indicate that a second soft pulse probably occurred in this burst, as has been observed in other GRBs, notably GRB 050502B.
THE SIGNATURE OF THE CENTRAL ENGINE IN THE WEAKEST RELATIVISTIC EXPLOSIONS: GRB 100316D

We present late-time radio and X-ray observations of the nearby sub-energetic gamma-ray burst (GRB)100316D associated with supernova (SN) 2010bh. Our broad-band analysis constrains the explosion

The identification of Type Ib/c supernovae (SNe Ib/c) as gamma-ray burst (GRB) progenitors is motivated by the association of GRB 980425 with SN 1998bw and of GRB 030329 with SN 2003dh. While the

It is concluded that there does indeed exist a large population of under-energetic events, and this event--as well as the other nearby but somewhat controversial GRB 980425--is a clear outlier from the isotropic-energy/peak-energy relation and luminosity/spectral-lag relations that describe the majority of GRBs.

Radio observations of GRB030329 indicate a common origin for cosmic explosions in which the energy in the highest-velocity ejecta is extremely variable, and the contribution of the γ-rays is energetically minor.
