Three-Dimensional Relativistic Magnetohydrodynamic Simulations of Current-Driven Instability. II. Relaxation of Pulsar Wind Nebula
Yosuke Mizuno, Yuri Lyubarsky, Ken-Ichi Nishikawa +1
We have investigated the relaxation of a hydrostatic hot plasma column containing toroidal magnetic field by the Current-Driven (CD) kink instability as a model of pulsar wind nebu…
Fermi Large Area Telescope observations of Local Group galaxies: Detection of M31 and search for M33
LAT collaboration
Cosmic rays (CRs) can be studied through the galaxy-wide gamma-ray emission that they generate when propagating in the interstellar medium. The comparison of the diffuse signals fr…
Detection of a Thermal Spectral Component in the Prompt Emission of GRB 100724B
Sylvain Guiriec, Valerie Connaughton, Michael S. Briggs +29
Observations of GRB 100724B with the Fermi Gamma-Ray Burst Monitor (GBM) find that the spectrum is dominated by the typical Band functional form, which is usually taken to represen…
Insights Into the High-Energy Gamma-ray Emission of Markarian 501 from Extensive Multifrequency Observations in the Fermi Era
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +6
We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average LAT gamma-ray spectrum of Mrk 501 can be well descr…
Simulating Heliospheric and Solar Particle Diffusion using the Parker Spiral Geometry
R. C. Tautz, A. Shalchi, A. Dosch
Cosmic Ray transport in curved background magnetic fields is investigated using numerical Monte-Carlo simulation techniques. Special emphasis is laid on the Solar system, where the…
Fermi-LAT Search for Pulsar Wind Nebulae around gamma-ray Pulsars
The Fermi LAT Collaboration, Pulsar Timing Consortium
The high sensitivity of the Fermi-LAT (Large Area Telescope) offers the first opportunity to study faint and extended GeV sources such as pulsar wind nebulae (PWNe). After one year…
Magnetic Field Amplification by Turbulence in A Relativistic Shock Propagating through An Inhomogeneous Medium
Yosuke Mizuno, Martin Pohl, Jacek Niemiec +3
We perform two-dimensional relativistic magnetohydrodynamic simulations of a mildly relativistic shock propagating through an inhomogeneous medium. We show that the postshock regio…
Multi-wavelength Observations of the Flaring Gamma-ray Blazar 3C 66A in 2008 October
LAT collaboration, A. A. Abdo et al., the VERITAS collaboration +4
The BL Lacertae object 3C 66A was detected in a flaring state by the Fermi Large Area Telescope (LAT) and VERITAS in 2008 October. In addition to these gamma-ray observations, F-GA…
Constraints on the Cosmic-Ray Density Gradient beyond the Solar Circle from Fermi gamma-ray Observations of the Third Galactic Quadrant
Fermi LAT Collaboration
We report an analysis of the interstellar -ray emission in the third Galactic quadrant measured by the {Fermi} Large Area Telescope. The window encompassing the Galactic plane f…
Search for Gravitational Wave Bursts from Six Magnetars
J. Abadie, B. P. Abbott, R. Abbott +765
Soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are thought to be magnetars: neutron stars powered by extreme magnetic fields. These rare objects are characterized b…
Gamma-ray flares from the Crab Nebula
LAT Collaboration
A young and energetic pulsar powers the well-known Crab Nebula. Here we describe two separate gamma-ray (photon energy >100 MeV) flares from this source detected by the Large Area…
Search for gamma-ray emission from magnetars with the Fermi Large Area Telescope
LAT collaboration
We report on the search for 0.1-10 GeV emission from magnetars in 17 months of Fermi Large Area Telescope (LAT) observations. No significant evidence for gamma-ray emission from an…
Studying Frequency Relations of kHz QPOs for 4U 1636-53 and Sco X-1: Observations Confront Theories
Yong-Feng Lin, Martin Boutelier, Didier Barret +1
By fitting the frequencies of simultaneous lower and upper kilohertz Quasi-Periodic Oscillations (kHz QPOs) in two prototype neutron star QPO sources (4U~1636-536 and Sco X-1), we…
When A Standard Candle Flickers
Colleen A. Wilson-Hodge, Michael L. Cherry, Wayne H. Baumgartner +27
The Crab Nebula is the only hard X-ray source in the sky that is both bright enough and steady enough to be easily used as a standard candle. As a result, it has been used as a nor…
First Results from Fermi GBM Earth Occultation Monitoring: Observations of Soft Gamma-Ray Sources Above 100 keV
Gary L. Case, Michael L. Cherry, James C. Rodi +15
The NaI and BGO detectors on the Gamma-ray Burst Monitor (GBM) on Fermi are now being used for long-term monitoring of the hard X-ray/low energy gamma-ray sky. Using the Earth occu…
A New Discriminator for Gamma-Ray Burst Classification: The Epeak-Fluence Energy Ratio
A. Goldstein, R. D. Preece, M. S. Briggs
Using the derived gamma-ray burst E_peak and fluences from the complete BATSE 5B Spectral Catalog, we study the ensemble characteristics of the E_peak-fluence relation for GRBs. Th…
