FUSE Deuterium Observations: A Strong Case For Galactic Infall
Tijana Prodanovic, Brian D. Fields
Measurements of deuterium in the local interstellar medium have revealed large variations in D/H along different lines of sight. Moreover, recent {\it Far Ultraviolet Spectroscopic…
Cosmological Cosmic Rays: Sharpening the Primordial Lithium Problem
Tijana Prodanovic, Brian D. Fields
Cosmic structure formation leads to large-scale shocked baryonic flows which are expected to produce a cosmological population of structure-formation cosmic rays (SFCRs). Interacti…
Can Galactic Cosmic Rays Account for Solar 6Li Without Overproducing Gamma Rays?
T. Prodanovic, B. D. Fields
Cosmic-ray interactions with interstellar gas produces both 6Li, which accumulates in the interstellar medium (ISM), and mesons, which decay to gamma-rays which propagate thr…
Diffuse Gamma Rays from the Galactic Plane: Probing the "GeV Excess" and Identifying the "TeV Excess"
Tijana Prodanovic, Brian D. Fields, John F. Beacom
Pion decay gamma rays have long been recognized as a unique signature of hadronic cosmic rays and their interactions with the interstellar medium. We present a model-independent wa…
Probing Primordial and Pre-Galactic Lithium with High Velocity Clouds
Tijana Prodanovic, Brian D. Fields
The pre-Galactic abundance of lithium offers a unique window into non-thermal cosmological processes. The primordial Li abundance is guaranteed to be present and probes big bang nu…
Lithium-6 and Gamma Rays: Complementary Constraints on Cosmic-Ray History
Brian D. Fields, Tijana Prodanovic
The rare isotope 6Li is made only by cosmic rays, dominantly in alpha+alpha fusion reactions with ISM helium. Consequently, this nuclide provides a unique diagnostic of the history…
