Time-Dependent Electron Acceleration in Pulsar-Wind Termination Shocks: Application to the 2011 April Crab Nebula Gamma-Ray Flare

John J. Kroon, Peter A. Becker, Justin D. Finke

The -ray flares from the Crab nebula observed by {\it AGILE} and {\it Fermi}-LAT between 2007-2013 reached GeV photon energies and lasted several days. The strongest emission, o…

A dearth of small particles in the transiting material around the white dwarf WD 1145+017

S. Xu, S. Rappaport, R. van Lieshout +35

White dwarf WD 1145+017 is orbited by several clouds of dust, possibly emanating from actively disintegrating bodies. These dust clouds reveal themselves through deep, broad, and e…

Extended gamma-ray sources around pulsars constrain the origin of the positron flux at Earth

A. U. Abeysekara, A. Albert, R. Alfaro +113

The unexpectedly high flux of cosmic ray positrons detected at Earth may originate from nearby astrophysical sources, dark matter, or unknown processes of cosmic-ray secondary prod…

2FGL J0846.0+2820: A new neutron star binary with a giant secondary and variable -ray emission

Samuel J. Swihart, Jay Strader, Tyrel J. Johnson +11

We present optical photometric and spectroscopic observations of the likely stellar counterpart to the unassociated \emph{Fermi}-Large Area Telescope (LAT) -ray source 2FGL J084…

High-Energy Variability of PSR J1311-3430

Hongjun An, Roger W. Romani, Tyrel Johnson +2

We have studied the variability of the black-widow type binary millisecond pulsar PSR J13113430 from optical to gamma-ray energies. We confirm evidence for orbital modulation in…

A Steady-State Spectral Model For Electron Acceleration And Cooling In Blazar Jets: Application To 3C 279

Tiffany R. Lewis, Justin D. Finke, Peter A. Becker

We introduce a new theoretical model to describe the emitting region in a blazar jet. We assume a one-zone leptonic picture, and construct the particle transport equation for a pla…
