X-shooter, the new wide band intermediate resolution spectrograph at the ESO Very Large Telescope
- J. Vernet, H. Dekker, +87 authors A. Zacchei
- Physics
- 10 October 2011
X-shooter is the first 2nd generation instrument of the ESO Very Large Telescope(VLT). It is a very efficient, single-target, intermediate-resolution spectrograph that was installed at the Cassegrain… Expand

Long γ-ray bursts and core-collapse supernovae have different environments

When massive stars exhaust their fuel, they collapse and often produce the extraordinarily bright explosions known as core-collapse supernovae. On occasion, this stellar collapse also powers an even… Expand
An Extremely Luminous Panchromatic Outburst from the Nucleus of a Distant Galaxy
A recent bright emission observed by the Swift satellite is due to the sudden accretion of a star onto a massive black hole. Variable x-ray and γ-ray emission is characteristic of the most extreme… Expand
A γ-ray burst at a redshift of z ≈ 8.2
Long-duration γ-ray bursts (GRBs) are thought to result from the explosions of certain massive stars, and some are bright enough that they should be observable out to redshifts of z > 20 using… Expand
A very energetic supernova associated with the γ-ray burst of 29 March 2003

- Physics
- Nature
- 17 June 2003
Over the past five years evidence has mounted that long-duration (>2 s) γ-ray bursts (GRBs)—the most luminous of all astronomical explosions—signal the collapse of massive stars in our Universe. This… Expand
A short γ-ray burst apparently associated with an elliptical galaxy at redshift z = 0.225

- Physics
- Nature
- 31 May 2005
Gamma-ray bursts (GRBs) come in two classes: long (> 2 s), soft-spectrum bursts and short, hard events. Most progress has been made on understanding the long GRBs, which are typically observed at… Expand
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… Expand
Swift identification of dark gamma-ray bursts
- P. Jakobsson, J. Hjorth, +4 authors J. Gorosabel
- Physics
- 1 November 2004
We present an optical flux vs. X-ray flux diagram for all known gamma-ray bursts (GRBs) for which an X-ray afterglow has been detected. We propose an operational definition of dark bursts as those… Expand
