A celestial gamma-ray foreground due to the albedo of small solar system bodies and a remote probe of the interstellar cosmic ray spectrum (2007)

Moskalenko, Igor V., Porter, Troy A., Digel, Seth W., Michelson, Peter F., Ormes, Jonathan F.

We calculate the gamma-ray albedo flux from cosmic-ray (CR) interactions with the solid rock and ice in Main Belt asteroids (MBAs), Jovian and Neptunian Trojan asteroids, and Kuiper Belt objects...

Measuring 10-1000 GeV Cosmic Ray Electrons with GLAST/LAT (2007)

Moiseev, Alexander A., Ormes, Jonathan F., Moskalenko, Igor V.

We present here the capabilities of the GLAST Large Area Telescope to detect cosmic ray high-energy (HE) electrons in the energy range from 10 GeV to 1 TeV. We also discuss the science topics that...

Igor V. Moskalenko, Andrew W. Strong, Jonathan F. Ormes, Marius S. Potgieter

High-energy collisions of cosmic-ray nuclei with interstellar gas are believed to be the mechanism producing the majority of cosmic-ray antiprotons. Because of the kinematics of the process, they are...

Secondary antiprotons and propagation of cosmic rays in the galaxy and heliosphere (2002)

Moskalenko, Igor V., Strong, Andrew W., Ormes, Jonathan F., Potgieter, Marius S.

High-energy collisions of cosmic-ray nuclei with interstellar gas are believed to be the mechanism producing the majority of cosmic-ray antiprotons. Because of the kinematics of the process, they are...

Illuminating dark matter and primordial black holes with interstellar antiprotons (1998)

Wells, James D., Moiseev, Alexander, Ormes, Jonathan F.

Interstellar antiproton fluxes can arise from dark matter annihilating or decaying into quarks or gluons that subsequently fragment into antiprotons. Evaporation of primordial black holes also can...
