The Fermi GBM Gamma-Ray Burst Catalog: The First Two Years
William S. Paciesas, Charles A. Meegan, Andreas von Kienlin +26
The Fermi Gamma-ray Burst Monitor (GBM) is designed to enhance the scientific return from Fermi in studying gamma-ray bursts (GRBs). In its first two years of operation GBM trigger…
Anomalies in low-energy Gamma-Ray Burst spectra with the Fermi Gamma-Ray Burst Monitor
Dave Tierney, Sheila McBreen, Robert D. Preece +15
A Band function has become the standard spectral function used to describe the prompt emission spectra of gamma-ray bursts (GRBs). However, deviations from this function have previ…
Uncovering low-level Fermi/GBM emission using orbital background subtraction
Gerard Fitzpatrick, Valerie Connaughton, Sheila McBreen +1
The secondary instrument onboard Fermi, the Gamma-ray Burst Monitor (GBM) is an all sky monitor consisting of 14 scintillation detectors. When analysing transient events such as Ga…
Constraints on the Synchrotron Shock Model for the Fermi GBM Gamma-Ray Burst 090820A
J. Michael Burgess, Robert D. Preece, Matthew G. Baring +25
Discerning the radiative dissipation mechanism for prompt emission in Gamma-Ray Bursts (GRBs) requires detailed spectroscopic modeling that straddles the peak in the 100 k…
The Fermi GBM Gamma-Ray Burst Spectral Catalog: The First Two Years
Adam Goldstein, J. Michael Burgess, Robert D. Preece +25
We present systematic spectral analyses of GRBs detected by the Fermi Gamma-Ray Burst Monitor (GBM) during its first two years of operation. This catalog contains two types of spec…
A New Derivation of GRB Jet Opening Angles from the Prompt Gamma-Ray Emission
Adam Goldstein, Robert D. Preece, Michael S. Briggs +24
The jet opening angle of gamma-ray bursts (GRBs) is an important parameter for determining the characteristics of the progenitor, and the information contained in the opening angle…
The Fermi GBM Gamma-Ray Burst Spectral Catalog: Four Years Of Data
David Gruber, Adam Goldstein, Victoria Weller von Ahlefeld +29
In this catalog we present the updated set of spectral analyses of GRBs detected by the Fermi Gamma-Ray Burst Monitor (GBM) during its first four years of operation. It contains tw…
Temporal Deconvolution study of Long and Short Gamma-Ray Burst Light curves
P. N. Bhat, Michael S. Briggs, Valerie Connaughton +24
The light curves of Gamma-Ray Bursts (GRBs) are believed to result from internal shocks reflecting the activity of the GRB central engine. Their temporal deconvolution can reveal p…
Compton scattering in terrestrial gamma-ray flashes detected with the Fermi gamma-ray burst monitor
Gerard Fitzpatrick, Eric Cramer, Sheila McBreen +11
Terrestrial gamma-ray flashes (TGFs) are short intense flashes of gamma rays associated with lightning activity in thunderstorms. Using Monte Carlo simulations of the relativistic…
Background estimation in a wide-field background-limited instrument such as Fermi GBM
Gerard Fitzpatrick, Sheila McBreen, Valerie Connaughton +2
The supporting instrument on board the Fermi Gamma-ray Space Telescope, the Gamma-ray Burst Monitor (GBM) is a wide-field gamma-ray monitor composed of 14 individual scintillation…
First-year Results of Broadband Spectroscopy of the Brightest Fermi-GBM Gamma-Ray Bursts
Elisabetta Bissaldi, Andreas von Kienlin, Chryssa Kouveliotou +26
We present here our results of the temporal and spectral analysis of a sample of 52 bright and hard gamma-ray bursts (GRBs) observed with the Fermi Gamma-ray Burst Monitor (GBM) du…
The 2nd Fermi GBM Gamma-Ray Burst Catalog: The First Four Years
Andreas von Kienlin, Charles A. Meegan, William S. Paciesas +30
This is the second of a series of catalogs of gamma-ray bursts (GRBs) observed with the Fermi Gamma-ray Burst Monitor (GBM). It extends the first two-year catalog by two more years…
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 3rd Fermi GBM Gamma-Ray Burst Catalog: The First Six Years
P. Narayana Bhat, Charles A. Meegan, Andreas von Kienlin +30
Since its launch in 2008, the Fermi Gamma-ray Burst Monitor (GBM) has triggered and located on average approximately two gamma-ray bursts (GRB) every three days. Here we present th…
Pulse properties of terrestrial gamma-ray flashes detected by the Fermi Gamma-Ray Burst Monitor
Suzanne Foley, Gerard Fitzpatrick, Michael S. Briggs +17
The Gamma-ray Burst Monitor (GBM) on board the Fermi Gamma-ray Space Telescope has triggered on over 300 terrestrial gamma-ray flashes (TGFs) since its launch in June 2008. With 14…
