On a possible origin of the gamma-ray excess around the Galactic Center
Dmitry O. Chernyshov, Andrei E. Egorov, Vladimir A. Dogiel +1
Recent observations of gamma-rays with the Fermi Large Area Telescope (LAT) in the direction of the inner Galaxy revealed a mysterious GeV excess. Its intensity is significantly ab…
Exclusion of cosmic rays from molecular clouds by self-generated electric fields
Kedron Silsbee, Alexei V. Ivlev
It was recently discovered that in some regions of the Galaxy, the cosmic ray (CR) abundance is several orders of magnitude higher than previously thought. Additionally, there is e…
Formation of the cosmic-ray halo: Galactic spectrum of primary cosmic rays
V. A. Dogiel, A. V. Ivlev, D. O. Chernyshov +1
A self-consistent model of a one-dimensional cosmic-ray (CR) halo around the Galactic disk is formulated with the restriction to a minimum number of free parameters. It is demonstr…
Diffusive Versus Free-Streaming Cosmic Ray Transport in Molecular Clouds
Kedron Silsbee, Alexei V. Ivlev
Understanding the cosmic ray (CR) ionization rate is crucial in order to simulate the dynamics of, and interpret the chemical species observed in molecular clouds. Calculating the…
Magnetic Mirroring and Focusing of Cosmic Rays
Kedron Silsbee, Alexei V. Ivlev, Marco Padovani +1
We study the combined impact of magnetic mirroring and focusing on the ionization by cosmic rays (CRs) in dense molecular clouds and circumstellar disks. We show that for effective…
Cosmic-ray ionisation in circumstellar discs
Marco Padovani, Alexei V. Ivlev, Daniele Galli +1
Galactic cosmic rays are a ubiquitous source of ionisation of the interstellar gas, competing with UV and X-ray photons as well as natural radioactivity in determining the fraction…
