Estimating Long GRB Jet Opening Angles and Rest-Frame Energetics
Adam Goldstein, Valerie Connaughton, Michael S. Briggs +1
We present a method to estimate the jet opening angles of long duration Gamma-Ray Bursts (GRBs) using the prompt gamma-ray energetics and an inversion of the Ghirlanda relation, wh…
Do the Fermi Gamma-Ray Burst Monitor and Swift Burst Alert Telescope see the Same Short Gamma-Ray Bursts?
Eric Burns, Valerie Connaughton, Bin-Bin Zhang +5
Compact binary system mergers are expected to generate gravitational radiation detectable by ground-based interferometers. A subset of these, the merger of a neutron star with anot…
NuSTAR discovery of a cyclotron absorption line in the transient X-ray pulsar 2S 1553-542
Sergey S. Tsygankov, Alexander A. Lutovinov, Roman A. Krivonos +4
We report results of a spectral and timing analysis of the poorly studied transient X-ray pulsar 2S 1553-542 using data collected with the NuSTAR and Chandra observatories and the…
Investigation of Primordial Black Hole Bursts using Interplanetary Network Gamma-ray Bursts
T. N. Ukwatta, K. Hurley, J. H MacGibbon +22
The detection of a gamma-ray burst (GRB) in the solar neighborhood would have very important implications for GRB phenomenology. The leading theories for cosmological GRBs would no…
Enabling high confidence detections of gravitational-wave bursts
Tyson B. Littenberg, Jonah B. Kanner, Neil J. Cornish +1
With the advanced LIGO and Virgo detectors taking observations the detection of gravitational waves is expected within the next few years. Extracting astrophysical information from…
Multi-wavelength light curve evolution of Swift J1357.2-0933 during its 2011 outburst
Shan-Shan Weng, Shuang-Nan Zhang
Swift J1357.2-0933 underwent an episodic accretion in 2011 and provided very regular temporal and spectral evolution, making it an ideal source for exploring the nature of very fai…
Hydrostatic and Caustic Mass Profiles of Galaxy Clusters
Ben J. Maughan, Paul A. Giles, Kenneth J. Rines +4
We compare X-ray and caustic mass profiles for a sample of 16 massive galaxy clusters. We assume hydrostatic equilibrium in interpreting the X-ray data, and use large samples of cl…
Evolution of Global Relativistic Jets: Collimations and Expansion with kKHI and the Weibel Instability
K. I Nishikawa, J. T. Frederiksen, A. Nordlund +10
One of the key open questions in the study of relativistic jets is their interaction with the environment. Here, we study the initial evolution of both electron-proton and electron…
Efficient Production of High-energy Nonthermal Particles during Magnetic Reconnection in a Magnetically-dominated Ion-Electron Plasma
Fan Guo, Xiaocan Li, Hui Li +6
Magnetic reconnection is a leading mechanism for dissipating magnetic energy and accelerating nonthermal particles in Poynting-flux dominated flows. In this letter, we investigate…
The optical identifcation of events with poorly defined locations: The case of the Fermi GBM GRB140801A
V. M. Lipunov, J. Gorosabel, M. V. Pruzhinskaya +50
We report the early discovery of the optical afterglow of gamma-ray burst (GRB) 140801A in the 137 deg 3- error-box of the Fermi Gamma-ray Burst Monitor (GBM). MASTER is the…
The Transient Accereting X-Ray Pulsar XTE J1946+274: Stability of the X-Ray Properties at Low Flux and Updated Orbital Solution
Diana M. Marcu-Cheatham, Katja Pottschmidt, Matthias Kühnel +19
We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J…
Rossby Wave Green's Functions in an Azimuthal Wind
G. M. Webb, C. T. Duba, Q. Hu
Green's functions for Rossby waves in an azimuthal wind are obtained, in which the stream-function depends on , and , where is cylindrical radius and is the a…
MUSE sneaks a peek at extreme ram-pressure stripping events. II. The physical properties of the gas tail of ESO137-001
Matteo Fossati, Michele Fumagalli, Alessandro Boselli +3
We present a study of the physical properties of the disc and tail of ESO137-001, a galaxy suffering from extreme ram-pressure stripping during its infall into the Norma cluster. W…
Chandra Measurements of a Complete Sample of X-ray Luminous Galaxy Clusters: The Luminosity-Mass Relation
P. A. Giles, B. J. Maughan, H. Dahle +6
We present the results of work involving a statistically complete sample of 34 galaxy clusters, in the redshift range 0.15z0.3 observed with . We investigate the…

H. Miraghaei, H. G. Khosroshahi, C. Sengupta +3
We study Active Galactic Nucleus (AGN) activity in the fossil galaxy cluster, RX J1416.4+2315. Radio observations were carried out using Giant Metrewave Radio Telescope (GMRT) at t…
An observational revisit of band-split solar type-II radio bursts
Guohui Du, Xiangliang Kong, Yao Chen +3
Band split of solar type II radio bursts, discovered several decades ago, is a fascinating phenomenon with the type-II lanes exhibiting two almost-parallel sub-bands with similar m…
