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…
