WebOct 29, 2009 · Here we report that GRB 090423 lies at a redshift of z ≈ 8.2, implying that massive stars were being produced and dying as GRBs ∼ 630 Myr after the Big Bang. The burst also pinpoints the... The overdensity was discovered using data from different space telescopes operating at gamma-ray and X-ray wavelengths, plus some data from ground-based telescopes. By the end of 2012 they successfully recorded 283 GRBs and measured their redshifts spectroscopically. They subdivided them to different group … See more The Hercules–Corona Borealis Great Wall or simply the Great Wall is the largest known structure in the observable universe, measuring approximately 10 billion light-years in length (the observable universe is about 93 billion … See more The authors of the paper concluded that a structure was the possible explanation of the clustering, but they never associated any name with it. … See more The team subdivides the 283 GRBs into nine groups in sets of 31 GRBs. At least three different methods have been used to reveal the significance of the clustering. Two-dimensional … See more • CfA2 Great Wall • The Giant Arc, another large cosmic structure • Large-scale structure of the universe • List of largest cosmic structures See more The paper states that "14 of the 31 GRBs are concentrated within 45 degrees of the sky", which translates to the size of about 10 billion light-years (3 See more Some studies have cast doubt on the existence of the HCB. A study in 2016 found that the observed distribution of GRBs was consistent with what could be derived from Monte Carlo simulations, but was below the 95% probability threshold (p < .05) of … See more
