The Swift Gamma-Ray Burst Mission
- N. GehrelsG. Chincarini W. Zhang
- 12 May 2004
Physics
The Swift mission will determine the origin of GRB, classify GRBs and search for new types, study the interaction of the ultrarelativistic outflows of GRBs with their surrounding medium, and use GRBs to study the early universe out to z >10.
HIGH-REDSHIFT GALAXIES IN THE HUBBLE DEEP FIELD : COLOUR SELECTION AND STAR FORMATION HISTORY TO Z 4
- P. MadauH. FergusonM. DickinsonM. GiavaliscoC. SteidelA. Fruchter
- 31 July 1996
Physics
The Lyman decrement associated with the cumulative effect of H I in QSO absorption systems along the line of sight provides a distinctive feature for identifying galaxies at z ≳ 2.5. Colour criteria,…
A PHOTOMETRIC REDSHIFT OF z ∼ 9.4 FOR GRB 090429B
- A. CucchiaraA. Cucchiara P. D’Avanzo
- 25 May 2011
Physics
Gamma-ray bursts (GRBs) serve as powerful probes of the early universe, with their luminous afterglows revealing the locations and physical properties of star-forming galaxies at the highest…
High-Redshift Supernova Rates
- T. DahlénL. Strolger J. Tonry
- 24 June 2004
Physics
We use a sample of 42 supernovae detected with the Advanced Camera for Surveys on board the Hubble Space Telescope as part of the Great Observatories Origins Deep Survey to measure the rate of…
An Extremely Luminous Panchromatic Outburst from the Nucleus of a Distant Galaxy
Multiwavelength observations of a unique γ-ray–selected transient detected by the Swift satellite, accompanied by bright emission across the electromagnetic spectrum, and whose properties are unlike any previously observed source are presented.
A Possible Relativistic Jetted Outburst from a Massive Black Hole Fed by a Tidally Disrupted Star
- J. BloomD. Giannios A. Horst
- 16 April 2011
Physics
Observations suggest a sudden accretion event onto a central MBH of mass about 106 to 107 solar masses, which leads to a natural analogy of Sw 1644+57 to a temporary smaller-scale blazar.
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…
Long γ-ray bursts and core-collapse supernovae have different environments
- A. FruchterA. Levan S. Woosley
- 20 March 2006
Physics
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…
A millisecond pulsar in an eclipsing binary
- A. FruchterD. StinebringJ. Taylor
- 1 May 1988
Physics
We have discovered a remarkable pulsar with period 1.6 ms, moving in a nearly circular 9.17-h orbit around a low-mass companion star. At an observing frequency of 430 MHz, the pulsar, PSR1957 + 20,…
A very energetic supernova associated with the γ-ray burst of 29 March 2003
- J. HjorthJ. Sollerman R. Wijers
- 17 June 2003
Physics
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…
