Lower limits on the nucleosynthezis of Ti and Fe in the dynamic spiral-arms model
David Benyamin, Nir J. Shaviv
We have previously focused on studying the electron-capture isotopes within the dynamic spiral-arms model and empirically derived the energy dependence of the electron attachment r…
Electron-Capture Isotopes could Constrain Cosmic-Ray Propagation Models
David Benyamin, Nir J. Shaviv, Tsvi Piran
Electron capture (EC) isotopes are known to provide constraints on the low energy behavior of cosmic rays (CRs), such as re-acceleration. Here we study the EC isotopes within the f…
Reconciling the diffuse Galactic gamma-ray and the cosmic ray spectra
Lara Nava, David Benyamin, Tsvi Piran +1
Most of the diffuse Galactic GeV gamma-ray emission is produced via collisions of cosmic ray (CR) protons with ISM protons. As such the observed spectra of the gamma-rays and the C…
The B/C and sub-Iron/Iron Cosmic ray ratios - further evidence in favor of the spiral arm diffusion model
David Benyamin, Ehud Nakar, Tsvi Piran +1
The Boron to Carbon (B/C) and sub-Fe/Fe ratios provides an important clue on Cosmic Ray (CR) propagation within the Galaxy. These ratios estimate the grammage that the CR traverse…
Recovering the observed B/C ratio in a dynamic spiral-armed cosmic ray model
David Benyamin, Ehud Nakar, Tsvi Piran +1
We develop a fully three dimensional numerical code describing the diffusion of cosmic rays in the Milky Way. It includes the nuclear spallation chain up to Oxygen, and allows the…
