Lampi gamma 10 54 erg
Tīmeklis2024. gada 16. okt. · The average GRB produces “only” 10 52, 10 53 erg of energy, and is located at redshift 2-3. Events that unleash 10 54 erg are rare, and their occurrence is even rarer at such “low redshift” from us. It has been calculated that it might take several decades before another GRB like 130427A takes place again. TīmeklisThe isotropic γ-ray energy release is ~10 54 erg, rendering it the most powerful explosion among gamma-ray bursts (GRBs) with a redshift z <= 0.5. The emission …

Tīmeklisγ,iso∼ 1055 erg), the supergiant envelope hides the initial bright phase in the cocoon component, leading to a GRB with a long duration∼1000(1+z)s and an ordinary isotropic luminosity∼ 1052 erg s−1 (∼ 10−9 erg cm −2 s 1 at redshift z ∼ 20), although these quantities are found to be sensitive to the core and envelope mass. We ... Tīmeklis1. Introduction. Gamma-ray bursts (GRBs) are immensely powerful stellar explosions with an equivalent isotropic energy, E iso that can exceed 10 54 erg [1]. Their light curves consist of intense and complex pulses that typically last for a few seconds and their spectra are nonthermal peaking between 10 and 10 4 keV. Although the …

Present data show these requirements to exceed 10 54 ergs in gamma ray production for the most energetic bursts if the bursts are isotropic. Such energies are regarded as an “energy crisis” for some classes of …
Tīmeklis2024. gada 25. aug. · Gamma-ray bursts (GRBs) are famous for being the brightest astrophysical explosions, boasting apparent energy releases of up to 8.8 × 10 54 erg (about five times the sun’s mass in energy). If the burst lasts for fewer than a couple seconds, it is classified as a short GRB — thought to be the result of neutron star … Tīmeklis2024. gada 14. jūn. · “I lampi di raggi gamma, i fenomeni transienti più potenti in cielo, rilasciano energia fino a valori dell’ordine di 10^54 erg in pochi secondi”, afferma …
TīmeklisIn a few dozen seconds, gamma ray bursts (GRBs) emit up to 10 54 erg in terms of an equivalent isotropically radiated energy E iso, so they can be observed up to z 10. Thus, these phenomena appear to be very promising tools to describe the expansion rate history of the universe.
