The Fourth Fermi-GBM Gamma-Ray Burst Catalog: A Decade of Data

Abstract: We present the fourth in a series of catalogs of gamma-ray bursts (GRBs) observed with Fermi 's Gamma-Ray Burst Monitor (Fermi -GBM). It extends the six year catalog by four more years, now covering the 10 year time period from trigger enabling on 2008 July 12 to 2018 July 11. During this time period GBM triggered almost twice a day on transient events of which we identified 2356 as cosmic GRBs. Additional trigger events were due to solar flare events, magnetar burst activities, and terrestrial gamma-ray flash… Show more

“…The spectral and timing properties for both short and long GRBs suggest that the gamma-ray component of the prompt emission is produced in highly relativistic jets (Gehrels & Razzaque 2013). However, the physical properties of these jets, such as their structure and magnetic topology, remain poorly understood despite the plethora of flux, spectral, and timing measurements produced over the last five decades; see for example Kienlin et al (2020), Lien et al (2016), Meegan et al (1997) and Tsvetkova et al (2017c).…”

“…The accompanying plasma continues its outward flow with a bulk Lorentz factor G ej ⇠ 100 and kinetic energy ⇠ 3 ⇥ 10 46 erg 21,22 . Such a high Lotentz factor is in contrast to the MGFs observed in the Milky Way that powered only mildly relativistic outflows observed as radio nebulae 23,24 expanding at ⇠ .7c, where the much lower expansion velocity can be attributed to entrainment of a larger baryon mass. The inferred kinetic energy of the outflow from the MGF in Sculptor is, however, comparable with the total radiated energy in the initial spike, as also inferred for the previous local MGFs.…”
