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…

We present Sunyaev-Zel'dovich (SZ) effect observations of a sample of 25 massive relaxed galaxy clusters observed with the Sunyaev-Zel'dovich Array (SZA), an 8-element interferomet…
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…
Mode Properties of Flat-top Silver Nano-ridge Surface Plasmon Waveguides
Zeyu Pan, Junpeng Guo, Richard Soref +2
We investigate surface plasmon modes supported by flat-top silver nano-ridges. We calculate the mode electromagnetic field distribution, the dispersion curve, the travel range, and…
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…
Fermi Detection of a Luminous Gamma-ray Pulsar in a Globular Cluster
The Fermi LAT Collaboration
We report the Fermi Large Area Telescope detection of gamma-ray (>100 megaelectronvolts) pulsations from pulsar J1823-3021A in the globular cluster NGC 6624 with high significance…
Effects of Interface Roughness Scattering on Radio Frequency Performance of Silicon Nanowire Transistors
SungGeun Kim, Mathieu Luisier, Timothy B. Boykin +1
The effects of an atomistic interface roughness in n-type silicon nanowire transistors (SiNWT) on the radio frequency performance are analyzed. Interface roughness scattering (IRS)…
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…
Response to "Comment on `Resolving the 180deg Ambiguity in Solar Vector Magnetic Field Data: Evaluating the Effects of Noise, Spatial Resolution, and Method Assumptions'"
K. D. Leka, Graham Barnes, G. Allen Gary +2
We address points recently discussed in Georgoulis (2011) in reference to Leka et al. (2009b). Most importantly, we find that the results of Georgoulis (2011) support a conclusion…
Effects of Interface Disorder on Valley Splitting in SiGe/Si/SiGe Quantum Wells
Zhengping Jiang, Neerav Kharche, Timothy Boykin +1
A sharp potential barrier at the Si/SiGe interface introduces valley splitting (VS), which lifts the 2-fold valley degeneracy in strained SiGe/Si/SiGe quantum wells (QWs). This wor…
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…
