Twinkling pulsar wind nebulae in the synchrotron cut-off regime and the gamma-ray flares in the Crab Nebula
A. M. Bykov, G. G. Pavlov, A. V. Artemyev +1
Synchrotron radiation of ultra-relativistic particles accelerated in a pulsar wind nebula may dominate its spectrum up to gamma-ray energies. Because of the short cooling time of t…

Recently, Fermi-LAT detected GeV emission during the X-ray flaring activity in GRB 100728A. We study various scenarios for its origin. The hard spectrum of the GeV emission favors…
Searching for soft relativistic jets in Core-collapse Supernovae with the IceCube Optical Follow-up Program
The IceCube Collaboration, R. Abbasi, Y. Abdou +262
Context. Transient neutrino sources such as Gamma-Ray Bursts (GRBs) and Supernovae (SNe) are hypothesized to emit bursts of high-energy neutrinos on a time-scale of \lesssim 100 s.…
Resonant Shattering of Neutron Star Crusts
David Tsang, Jocelyn S. Read, Tanja Hinderer +2
The resonant excitation of neutron star (NS) modes by tides is investigated as a source of short gamma-ray burst (sGRB) precursors. We find that the driving of a crust-core interfa…
Search for signatures of magnetically-induced alignment in the arrival directions measured by the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +496
We present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or `multiplets') which exhibit…
The spectrum of the recycled PSR J0437-4715 and its white dwarf companion

We present the most recent results from our investigation on Supergiant Fast X-ray Transients, a class of High-Mass X-ray Binaries, with a possible counterpart in the gamma-ray ene…
Unusual Central Engine Activity in the Double Burst GRB 110709B
Bin-Bin Zhang, David Burrows, Bing Zhang +11
The double burst, GRB 110709B, triggered Swift/BAT twice at 21:32:39 UT and 21:43:45 UT, respectively, on 9 July 2011. This is the first time we observed a GRB with two BAT trigger…
