WebGamma-ray burst has highest redshift yet seen Bursts signaling the collapse of stars more than 13 billion years ago should elucidate early star formation and the cosmic reion- ization it engendered. WebMay 27, 2011 · Gamma-ray bursts that are longer than two seconds are caused by the detonation of a rapidly rotating massive star at the end of its life on the main sequence. Jets of particles and gamma radiation are emitted in opposite directions from the stellar core as the star collapses. ... May 25, the team reported a redshift of 9.4 for GRB 090429B ...
WebHence, it is essential to characterize the properties of faint galaxies with significant Lyman continuum (LyC) photon leakage up to z ∼ 4 to define indirect indicators allowing analogs to be found at the highest redshift. Aims: Long gamma-ray bursts (LGRBs) typically explode in star-forming regions of faint, star-forming galaxies. WebDec 17, 2024 · Deep spectroscopy with Keck determined a redshift 10.957 for the galaxy “GN-z11”, supporting it as the most distant astrophysical object known to date. Meanwhile, a bright burst was...
WebJun 21, 2024 · Future missions for long gamma-ray burst (GRB) observations at high redshift, such as the High-z Gamma-ray bursts for Unraveling the Dark Ages Mission and the Transient High-Energy Sky and Early Universe Surveyor, will provide clues to the star formation history in our universe. WebThe observed sky distribution of weak gamma-ray bursts constrains the allowable geometrical models to sources in either a giant spherical galactic halo or to sources at cosmological distances. Observations of time dilation consistent with …
WebOct 18, 2024 · The race for the most distant object in the Universe has been played by long-duration gamma-ray bursts (GRBs), star-forming galaxies and quasars. GRBs took a temporary lead with the discovery of GRB 090423 at a redshift z=8.2, but now the record-holder is the galaxy GN-z11 at z=11.0. Despite this record, galaxies and quasars are …
