Time variability of TeV cosmic ray sky map
Rahul Kumar, Noemie Globus, David Eichler +1
The variation in the intensity of cosmic rays at small angular scales is attributed to the interstellar turbulence in the vicinity of the Solar system. We show that {a turbulent or…
Ultrahigh Energy Cosmic Rays: A Galactic Origin?
David Eichler, Noemie Globus, Rahul Kumar +1
It is suggested that essentially all of the UHECRs we detect, including those at the highest energy, originate in our Galaxy. It is shown that even if the density of sources decrea…
Electron Heating in a Relativistic, Weibel-Unstable Plasma
Rahul Kumar, David Eichler, Michael Gedalin
The dynamics of two initially unmagnetized relativistic counter-streaming homogeneous ion-electron plasma beams are simulated in two dimensions using the particle-in-cell (PIC) met…
The isotropy problem of Sub-ankle Ultra-high energy cosmic rays
Rahul Kumar, David Eichler
We study the time dependent propagation of sub-ankle ultra-high energy cosmic rays (UHECRs) originating from point-like Galactic sources. We show that drift in the Galactic magneti…
Search for long-lived gravitational-wave transients coincident with long gamma-ray bursts
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +875
Long gamma-ray bursts (GRBs) have been linked to extreme core-collapse supernovae from massive stars. Gravitational waves (GW) offer a probe of the physics behind long GRBs. We inv…
Is the Galactic Cosmic Ray Spectrum Constant in Time?
David Eichler, Rahul Kumar, Martin Pohl
The hypothesis is considered that the present Galactic cosmic ray spectrum is at present softer than its time average due to source intermittency. Measurements of muogenic nuclides…
