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 Significant Problem With Using the Amati Relation for Cosmological Purposes
Andrew C. Collazzi, Bradley E. Schaefer, Adam Goldstein +1
We consider the distribution of many samples of Gamma-Ray Bursts (GRBs) when plotted in a diagram with their bolometric fluence (Sbolo) versus the observed photon energy of peak sp…
An overview of the current understanding of Gamma-ray Bursts in the Fermi era
P. N. Bhat, S. Guiriec
Gamma-ray bursts are the most luminous explosions in the Universe, and their origin as well as mechanism are the focus of intense research and debate. More than three decades since…
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…
The cosmic-ray and gas content of the Cygnus region as measured in gamma rays by the Fermi Large Area Telescope
the Fermi LAT Collaboration
The Cygnus region hosts a giant molecular-cloud complex which actively forms massive stars. Interactions of cosmic rays with interstellar gas and radiation fields make it shine at…
Simultaneous multi-wavelength campaign on PKS 2005-489 in a high state
The H. E. S. S. Collaboration, the Fermi LAT Collaboration, : +345
The high-frequency peaked BL Lac object PKS 2005-489 was the target of a multi-wavelength campaign with simultaneous observations in the TeV gamma-ray (H.E.S.S.), GeV gamma-ray (Fe…
GBM Monitoring of Cyg X-1 During the Recent State Transition
G. L. Case, S. Baldridge, M. L. Cherry +5
Cygnus X-1 is a high-mass x-ray binary with a black hole compact object. It is normally extremely bright in hard x-rays and low energy gamma rays and resides in the canonical hard…
Unifying the Zoo of Jet-Driven Stellar Explosions
Davide Lazzati, Brian J. Morsony, Christopher H. Blackwell +1
We present a set of numerical simulations of stellar explosions induced by relativistic jets emanating from a central engine sitting at the center of compact, dying stars. We explo…
Fermi Large Area Telescope Observations of the Supernova Remnant G8.7-0.1
LAT Collaboration
We present a detailed analysis of the GeV gamma-ray emission toward the supernova remnant (SNR) G8.7-0.1 with the Large Area Telescope (LAT) onboard the \emph{Fermi} Gamma-ray Spac…
SN 2010ay is a Luminous and Broad-lined Type Ic Supernova within a Low-metallicity Host Galaxy
Nathan E. Sanders, A. M. Soderberg, S. Valenti +38
We report on our serendipitous pre-discovery detection and detailed follow-up of the broad-lined Type Ic supernova (SN) 2010ay at z = 0.067 imaged by the Pan-STARRS1 3pi survey jus…
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…
Burst and Persistent Emission Properties during the Recent Active Episode of the Anomalous X-ray Pulsar 1E 1841-045
Lin Lin, Chryssa Kouveliotou, Ersin Gogus +19
Swift/BAT detected the first burst from 1E 1841-045 in May 2010 with intermittent burst activity recorded through at least July 2011. Here we present Swift and Fermi/GBM observatio…
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…
Search for Gamma-ray Emission from X-ray Selected Seyfert Galaxies with Fermi-LAT
LAT Collaboration
We report on a systematic investigation of the gamma-ray properties of 120 hard X-ray-selected Seyfert galaxies classified as `radio-quiet' objects, utilizing the three-year accumu…
Measurement of separate cosmic-ray electron and positron spectra with the Fermi Large Area Telescope
The Fermi LAT Collaboration, M. Ackermann, M. Ajello +148
We measured separate cosmic-ray electron and positron spectra with the Fermi Large Area Telescope. Because the instrument does not have an onboard magnet, we distinguish the two sp…
