We present the results from a Hubble Space Telescope ACS study of the supernovae (SNe) associated with gamma-ray bursts (GRBs) 040924 (z = 0.86) and 041006 (z = 0.71). We find evidence that both GRBs were associated with an SN 1998bw-like supernova dimmed by ~1.5 and ~0.3 mag, respectively, making GRB 040924 the faintest GRB-associated SN ever detected. We study the luminosity dispersion in GRB/XRF-associated SNe and compare to local Type Ibc SNe from the literature. We find significant overlap… 

The GRB 060218/SN 2006aj event in the context of other gamma-ray burst supernovae

The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date and its early light curve includes an additional wavelength-dependent component, which can be interpreted as shock break-out, and is found to be subluminous and rapidly evolving.

Four GRB supernovae at redshifts between 0.4 and 0.8

Twenty years ago, GRB 980425/SN 1998bw revealed that long gamma-ray bursts (GRBs) are physically associated with broad-lined type-Ic supernovae (SNe). Since then more than 1000 long GRBs have been

A tale of two GRB-SNe at a common redshift of z = 0.54

We present ground-based and Hubble Space Telescope optical observations of the optical transients (OTs) of long-duration Gamma Ray Bursts (GRBs) 060729 and 090618, both at a redshift of z= 0.54. For

Diversity of gamma-ray burst energetics vs. supernova homogeneity

Aims. Long-duration gamma-ray bursts (GRBs) have been found to be associated with broad-lined type-Ic supernovae (SNe), but only a handful of cases have been studied in detail. Prompted by the


GRB 120422A is a nearby (z = 0.283) long-duration gamma-ray burst (LGRB) detected by Swift with Eγ, iso ∼ 4.5 × 1049 erg. It is also associated with the spectroscopically confirmed broad-lined Type

Evidence for a Supernova Associated with the X-Ray Flash 020903

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.

A search for Fermi bursts associated with supernovae and their frequency of occurrence

Context. Observations suggest that most long duration gamma-ray bursts (GRBs) are connected with broad-line supernovae Ib/c, (SNe-Ibc). The presence of GRB-SNe is revealed by rebrightenings emerging

No supernovae associated with two long-duration γ-ray bursts

It is now accepted that long-duration γ-ray bursts (GRBs) are produced during the collapse of a massive star1,2. The standard ‘collapsar’ model3 predicts that a broad-lined and luminous type Ic

Multiwavelength analysis of three supernovae associated with gamma-ray bursts observed by GROND

Context. After the discovery of the first connection between γ-ray bursts (GRBs) and supernovae (SNe) almost two decades ago, tens of SN-like rebrightenings have been discovered and about seven solid

Abstract We aim at characterizing SN 2013dx, associated with GRB 130702A, and their environment, through ground-based observational campaigns in the optical-IR band. We infer a synthesized 56Ni mass



An HST Search for Supernovae Accompanying X-Ray Flashes

We present the results from a Hubble Space Telescope ACS search for supernovae associated with X-ray flashes 020903, 040701, 040812, and 040916. We find strong evidence that XRF 020903 (z = 0.25) was

Photometry and Spectroscopy of GRB 030329 and Its Associated Supernova 2003dh: The First Two Months

We present extensive optical and infrared photometry of the afterglow of gamma-ray burst (GRB) 030329 and its associated supernova (SN) 2003dh over the first two months after detection (2003 March

The Detailed Optical Light Curve of GRB 030329

We present densely sampled BVRI light curves of the optical transient associated with the gamma-ray burst (GRB) 030329, the result of a coordinated observing campaign conducted at five observatories.

Optical and near-infrared observations of the gamma-ray burst GRB 031203, at z = 0.1055, are reported. A very faint afterglow is detected superposed onto the host galaxy in our first infrared JHK

A Systematic Analysis of Supernova Light in Gamma-Ray Burst Afterglows

We systematically reanalyzed all gamma-ray burst (GRB) afterglow data published through the end of 2002 in an attempt to detect the predicted supernova light component and to gain statistical insight

A Radio Survey of Type Ib and Ic Supernovae: Searching for Engine-driven Supernovae

The association of γ-ray bursts (GRBs) and core-collapse supernovae (SNe) of Type Ib and Ic was motivated by the detection of SN 1998bw in the error box of GRB 980425 and the now secure

We present spectroscopic and photometric observations of SN 1992ar, the most distant supernova (SN) in the Calán/Tololo Survey. We compare its spectrum with those of nearby Type Ia and Ic SNe and
