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…
Gamma-ray Activity in the Crab Nebula: The Exceptional Flare of April 2011
R. Buehler, J. D. Scargle, R. D. Blandford +18
The Large Area Telescope on board the Fermi satellite observed a gamma-ray flare in the Crab nebula lasting for approximately nine days in April of 2011. The source, which at optic…
Proto-Neutron Star Cooling with Convection: The Effect of the Symmetry Energy
Luke F. Roberts, Gang Shen, Vincenzo Cirigliano +3
We model neutrino emission from a newly born neutron star subsequent to a supernova explosion to study its sensitivity to the equation of state, neutrino opacities, and convective…
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…
Gamma-Ray Burst Dynamics and Afterglow Radiation from Adaptive Mesh Refinement, Special Relativistic Hydrodynamic Simulations
Fabio De Colle, Jonathan Granot, Diego Lopez-Camara +1
We report on the development of Mezcal-SRHD, a new adaptive mesh refinement, special relativistic hydrodynamics (SRHD) code, developed with the aim of studying the highly relativis…
Simulations of GRB Jets in a Stratified External Medium: Dynamics, Afterglow Lightcurves, Jet Breaks and Radio Calorimetry
Fabio De Colle, Enrico Ramirez-Ruiz, Jonathan Granot +1
The dynamics of GRB jets during the afterglow phase is most reliably and accurately modelled using hydrodynamic simulations. All published simulations, however, have considered onl…
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…
High-Resolution Simulations of Convection Preceding Ignition in Type Ia Supernovae Using Adaptive Mesh Refinement
A. Nonaka, A. J. Aspden, M. Zingale +3
We extend our previous three-dimensional, full-star simulations of the final hours of convection preceding ignition in Type Ia supernovae to higher resolution using the adaptive me…
From Convection to Explosion: End-to-End Simulation of Type Ia Supernovae
A. Nonaka, A. S. Almgren, J. B. Bell +3
We present our end-to-end capability for computing the convective phase through the explosion phase of Type Ia supernovae. We compute the convective phase up to the time of ignitio…
Multiwavelength Observations of the Previously Unidentified Blazar RX J0648.7+1516
E. Aliu, T. Aune, M. Beilicke +84
We report on the VERITAS discovery of very-high-energy (VHE) gamma- ray emission above 200 GeV from the high-frequency-peaked BL Lac object RXJ0648.7+1516 (GBJ0648+1516), associate…
Discovery of Nine Gamma-Ray Pulsars in Fermi-LAT Data Using a New Blind Search Method
H. J. Pletsch, L. Guillemot, B. Allen +28
We report the discovery of nine previously unknown gamma-ray pulsars in a blind search of data from the Fermi Large Area Telescope (LAT). The pulsars were found with a novel hierar…
Towards improving the prospects for coordinated gravitational-wave and electromagnetic observations
Ilya Mandel, Luke Z. Kelley, Enrico Ramirez-Ruiz
We discuss two approaches to searches for gravitational-wave (GW) and electromagnetic (EM) counterparts of binary neutron star mergers. The first approach relies on triggering arch…
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…
Long Gamma-Ray Transients from Collapsars
S. E. Woosley, Alexander heger
In the collapsar model for common gamma-ray bursts, the formation of a centrifugally supported disk occurs during the first 10 seconds following the collapse of the iron core…
Anisotropies in the diffuse gamma-ray background measured by Fermi LAT
A. Cuoco, T. Linden, M. N. Mazziotta +3
The small angular scale fluctuations of the (on large scale) isotropic gamma-ray background (IGRB) carry information about the presence of unresolved source classes. A guaranteed c…
Observation and Spectral Measurements of the Crab Nebula with Milagro
A. A. Abdo, B. T. Allen, T. Aune +32
The Crab Nebula was detected with the Milagro experiment at a statistical significance of 17 standard deviations over the lifetime of the experiment. The experiment was sensitive t…
Evidence for Type Ia Supernova Diversity from Ultraviolet Observations with the Hubble Space Telescope
Xiaofeng Wang, Lifan Wang, Alexei V. Filippenko +93
