Localization of Gamma-Ray Bursts using the Fermi Gamma-Ray Burst Monitor
V. Connaughton, M. S. Briggs, A. Goldstein +25
The Fermi Gamma-ray Burst Monitor (GBM) has detected over 1400 Gamma-Ray Bursts (GRBs) since it began science operations in July, 2008. We use a subset of over 300 GRBs localized b…
Imaging and spectroscopic observations of magnetic reconnection and chromospheric evaporation in a solar flare
Hui Tian, Gang Li, Katharine K. Reeves +5
Magnetic reconnection is believed to be the dominant energy release mechanism in solar flares. The standard flare model predicts both downward and upward outflow plasmas with speed…
Swift and Fermi observations of X-ray flares: the case of Late Internal Shock
E. Troja, L. Piro, V. Vasileiou +5
Simultaneous Swift and Fermi observations of gamma-ray bursts (GRBs) offer a unique broadband view of their afterglow emission, spanning more than ten decades in energy. We present…
Early-time VLA observations and broad-band afterglow analysis of the Fermi-LAT detected GRB 130907A
Péter Veres, Alessandra Corsi, Dale A. Frail +2
We present multi-wavelength observations of the hyper-energetic gamma-ray burst (GRB) 130907A, a Swift-discovered burst with early radio observations starting at hr aft…
A Monte Carlo Bayesian Search for the Plausible Source of the Telescope Array Hotspot
Hao-Ning He, Alexander Kusenko, Shigehiro Nagataki +3
The Telescope Array (TA) collaboration has reported a hotspot of 19 ultrahigh-energy cosmic rays (UHECRs). Using a universal model with one source and energy-dependent magnetic def…
Possible role of coronal streamer as magnetically-closed structure in shock-induced energetic electrons and metric type II radio bursts
Xiangliang Kong, Yao Chen, Fan Guo +4
Two solar type II radio bursts, separated by ~24 hours in time, are examined together. Both events are associated with coronal mass ejections (CMEs) erupting from the same active r…
Synchrotron Cooling in Energetic Gamma-Ray Bursts Observed by the Fermi Gamma-Ray Burst Monitor
Hoi-Fung Yu, Jochen Greiner, Hendrik van Eerten +15
We study the time-resolved spectra of eight GRBs observed by Fermi GBM in its first five years of mission, with 1 keV - 1 MeV fluence erg cm and signal-…
Constraints on Very High Energy Emission from GRB 130427A
E. Aliu, T. Aune, A. Barnacka +89
Prompt emission from the very fluent and nearby (z=0.34) gamma-ray burst GRB 130427A was detected by several orbiting telescopes and by ground-based, wide-field-of-view optical tra…
Finding and characterising WHIM structures using the luminosity density method
J. Nevalainen, L. J. Liivamagi, E. Tempel +12
We have developed a new method to approach the missing baryons problem. We assume that the missing baryons reside in a form of Warm Hot Intergalactic Medium, i.e. the WHIM. Our met…
High-energy electromagnetic offline follow-up of LIGO-Virgo gravitational-wave binary coalescence candidate events
Lindy Blackburn, Michael S. Briggs, Jordan Camp +5
We present two different search methods for electromagnetic counterparts to gravitational-wave (GW) events from ground-based detectors using archival NASA high-energy data from the…
A method to improve the sensitivity of radio telescopes
Richard Lieu, Tom W. B. Kibble, Lingze Duan
As an extension of the ideas of Hanbury-Brown and Twiss, a method is proposed to eliminate the phase noise of white chaotic light in the regime where it is dominant, and to measure…
Three-dimensional Magnetic Restructuring in Two Homologous Solar Flares in the Seismically Active NOAA AR 11283
Chang Liu, Na Deng, Jeongwoo Lee +6
We carry out a comprehensive investigation comparing the three-dimensional magnetic field restructuring, flare energy release, and the helioseismic response, of two homologous flar…
Limits on the strength of individual gravitational wave sources using high-cadence observations of PSR B1937+21
Shuxu Yi, Benjamin W. Stappers, Sotirios A. Sanidas +5
We present the results of a search for gravitational waves (GWs) from individual sources using high cadence observations of PSR B1937+21. The data were acquired from an intensive o…
Scaling Relations and X-ray Properties of Moderate-Luminosity Galaxy Clusters from 0.3 < z < 0.6 with XMM-Newton
Thomas Connor, Megan Donahue, Ming Sun +4
We present new X-ray temperatures and improved X-ray luminosity estimates for 15 new and archival XMM-Newton observations of galaxy clusters at intermediate redshift with mass and…
Genus Topology and Cross-Correlation of BICEP2 and Planck 353 GHz B-Modes: Further Evidence Favoring Gravity Wave Detection
Wesley N. Colley, J. Richard Gott
We have analyzed the genus topology of the BICEP2 B-modes and find them to be Gaussian random phase as expected if they have a cosmological origin. These BICEP2 B-modes can be prod…
Pitch-angle scattering of energetic particles with adiabatic focusing
R. C. Tautz, A. Shalchi, A. Dosch
Understanding turbulent transport of charged particles in magnetized plasmas often requires a model for the description of random variations in the particle's pitch angle. The Fokk…
Magnetic Flux Transport at the Solar Surface
