Fermi Detection of γ-ray emission from the M2 Soft X-ray Flare on 2010 June 12
Fermi GBM Collaboration, Fermi LAT Collaboration, B. R. Dennis +2
The GOES M2-class solar flare, SOL2010-06-12T00:57, was modest in many respects yet exhibited remarkable acceleration of energetic particles. The flare produced an ~50 s impulsive…
A Proposal to Localize Fermi GBM GRBs Through Coordinated Scanning of the GBM Error Circle via Optical Telescopes
T. N. Ukwatta, J. T. Linnemann, K. Tollefson +4
We investigate the feasibility of implementing a system that will coordinate ground-based optical telescopes to cover the Fermi GBM Error Circle (EC). The aim of the system is to l…
Searching for Unmodeled Sources Using the Earth Occultation Data from the Fermi GBM
James Rodi, Gary L. Case, Michael L. Cherry +5
Employing the 12 NaI detectors in the Fermi GBM, the Earth Occultation Technique (EOT) can be used to measure the fluxes of x-ray and gamma-ray sources. Each time a source passes b…
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…
The Lag-Luminosity Relation in the GRB Source-Frame: An Investigation with Swift BAT Bursts
T. N. Ukwatta, K. S. Dhuga, M. Stamatikos +12
Spectral lag, which is defined as the difference in time of arrival of high and low energy photons, is a common feature in Gamma-ray Bursts (GRBs). Previous investigations have sho…
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 keV…
