We present the systematic spectral analyses of gamma-ray bursts (GRBs) detected by the Fermi Gamma-Ray Burst Monitor (GBM) during its first ten years of operation. This catalog con…
Observation of inverse Compton emission from a long -ray burst
V. A. Acciari, S. Ansoldi, L. A. Antonelli +301
Long-duration gamma-ray bursts (GRBs) originate from ultra-relativistic jets launched from the collapsing cores of dying massive stars. They are characterised by an initial phase o…

We report on the observations of gamma-ray burst (GRB) 190114C by the Fermi Gamma-ray Space Telescope and the Neil Gehrels Swift Observatory. The early-time observations reveal mul…
How Pulses in Short Gamma-Ray Bursts Constrain HMXRB Evolution
Jon Hakkila, Robert D. Preece
We demonstrate how pulse structures in Short gamma-ray bursts (SGRBs), coupled with observations of GRB/GW 170817A, constrain the geometries of dying HMXRB systems composed of merg…
Gamma-ray burst models in light of the GRB 170817A - GW170817 connection
P. Veres, P. Mészáros, A. Goldstein +8
For the first time, a short gamma-ray burst (GRB) was unambiguously associated with a gravitational wave (GW) observation from a binary neutron star (NS) merger. This allows us to…

J. L. Racusin, E. Burns, A. Goldstein +138
We present the Fermi Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) observations of the LIGO binary black hole merger event GW151226 and candi- date LVT151012. No can…
Which ? - The Characteristic Energy of Gamma-Ray Burst Spectra
Robert Preece, Adam Goldstein, Narayana Bhat +3
A characteristic energy of individual gamma-ray burst (GRB) spectra can in most cases be determined from the peak energy of the energy density spectra (), called '$E_{…
The Fermi GBM gamma-ray burst time-resolved spectral catalog: brightest bursts in the first four years
Hoi-Fung Yu, Robert D. Preece, Jochen Greiner +17
We aim to obtain high-quality time-resolved spectral fits of gamma-ray bursts (GRBs) observed by the Gamma-ray Burst Monitor (GBM) on board the Fermi Gamma-ray Space Telescope. We…
The sharpness of gamma-ray burst prompt emission spectra
Hoi-Fung Yu, Hendrik J. van Eerten, Jochen Greiner +5
We aim to obtain a measure of the curvature of time-resolved spectra that can be compared directly to theory. This tests the ability of models such as synchrotron emission to expla…
Classification of Fermi Gamma-RAY Bursts
I. Horvath, L. G. Balázs, J. Hakkila +2
The Fermi GBM Catalog has been recently published. Previous classification analyses of the BATSE, RHESSI, BeppoSAX, and Swift databases found three types of gamma-ray bursts. Now w…
Improved limits on sterile neutrino dark matter from full-sky observations by the Fermi-GBM
Shunsaku Horiuchi, Kenny C. Y. Ng, Jennifer M. Gaskins +2
For the first time, we use the Gamma-ray Burst Monitor (GBM) on-board the Fermi satellite to search for sterile neutrino decay lines in the energy range 10-25 keV corresponding to…
Synchrotron Cooling in Energetic Gamma-Ray Bursts Observed by the Fermi Gamma-Ray Burst Monitor
Hoi-Fung Yu, Jochen Greiner, Hendrik van Eerten +15
We study the time-resolved spectra of eight GRBs observed by Fermi GBM in its first five years of mission, with 1 keV - 1 MeV fluence erg cm and signal-…
An Observed Correlation Between Thermal and Non-Thermal Emission in Gamma-Ray Bursts
J. Michael Burgess, Robert D. Preece, Felix Ryde +22
Recent observations by the Gamma-ray Space Telescope have confirmed the existence of thermal and non-thermal components in the prompt photon spectra of some Gamma-ray burst…
The Fermi GBM Gamma-Ray Burst Spectral Catalog: Four Years Of Data
