Isotropic Gamma-Ray Background: Cosmic-Ray Induced Albedo from Debris in the Solar System?

We calculate the gamma-ray albedo due to cosmic-ray interactions with debris (small rocks, dust, and grains) in the Oort Cloud. We show that under reasonable assumptions a significant proportion of what is called the "extragalactic gamma-ray background" could be produced at the outer frontier of the solar system and may be detectable by the Large Area Telescope, the primary instrument on the Fermi Gamma-Ray Space Telescope. If detected it could provide unique direct information about the total…

Extragalactic Gamma‐Ray Background
The origin of the extragalactic gamma-ray background (EGRB) is an important open issue in the gamma-ray astronomy. There are many theories about the origin of EGRB: (1) some truly diffuse processes,
Dissecting the Gamma-Ray Background in Search of Dark Matter
Several classes of astrophysical sources contribute to the approximately isotropic gamma-ray background measured by the Fermi Gamma-Ray Space Telescope. In this paper, we use Fermi's catalog of
We report on the detection of high-energy γ -ray emission from theMoon during the first 24 months of observations by the Fermi Large Area Telescope (LAT). This emission comes from particle cascades
Diffuse γ-ray emission from misaligned active galactic nuclei
Active galactic nuclei (AGNs) with jets seen at small viewing angles are the most luminous and abundant objects in the γ-ray sky. AGNs with jets misaligned along the line of sight appear fainter in
The spectrum of isotropic diffuse gamma-ray emission between 100 MeV and 820 GeV
The γ-ray sky can be decomposed into individually detected sources, diffuse emission attributed to the interactions of Galactic cosmic rays with gas and radiation fields, and a residual all-sky
Fermi has resolved several star-forming galaxies, but the vast majority of the star-forming universe is unresolved, and thus contributes to the extragalactic gamma-ray background (EGB). Here, we
Characterization of dark-matter-induced anisotropies in the diffuse gamma-ray background
The Fermi-LAT collaboration has recently reported the detection of angular power above the photon noise level in the diffuse gamma-ray background between 1 and 50 GeV. Such signal can be used to
The nature of the Diffuse Gamma-Ray Background
We review the current understanding of the diffuse gamma-ray background (DGRB). The DGRB is what remains of the total measured gamma-ray emission after the subtraction of the resolved sources and of
Gamma-ray and neutrino backgrounds as probes of the high-energy universe: hints of cascades, general constraints, and implications for TeV searches
Recent observations of isotropic diffuse backgrounds by Fermi and IceCube allow us to get more insight into distant very-high-energy (VHE) and ultra-high-energy (UHE) gamma-ray/neutrino emitters,
Constraining Dark Matter Properties with Gamma-Rays from the Galactic Center with Fermi-LAT
Abstract We study the capabilities of the Fermi–LAT instrument on board of the Fermi mission to constrain particle dark matter properties, as annihilation cross section, mass and branching ratio into


A Celestial Gamma-Ray Foreground Due to the Albedo of Small Solar System Bodies and a Remote Probe of the Interstellar Cosmic-Ray Spectrum
We calculate the γ-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 (KBOs)
The Gamma-ray Albedo of the Moon
We use the GEANT4 Monte Carlo framework to calculate the γ-ray albedo of the Moon due to interactions of cosmic-ray (CR) nuclei with moon rock. Our calculation of the albedo spectrum agrees with the
Cosmic gamma-ray background from structure formation in the intergalactic medium
It is shown that the shock waves induced by gravity in the gas of the intergalactic medium, during the formation of large-scale structures like filaments and sheets of galaxies, produce a population of highly relativistic electrons that scatter a small fraction of the cosmic microwave background photons in the local Universe up to gamma-ray energies, thereby providing the Gamma-ray background.
Gamma-ray emission from the solar halo and disk: a study with EGRET data
Context. The Sun has recently been predicted to be an extended source of gamma-ray emission, produced by inverse-Compton (IC) scattering of cosmic-ray (CR) electrons on the solar radiation field. The

Abstract Inverse Compton (IC) scattering by relativistic electrons produces a major component of the diffuse emission from the Galaxy. The photon fields involved are the cosmic microwave background
The Guaranteed Gamma-Ray Background
The diffuse extragalactic gamma-ray background (EGRB) above 100 MeV encodes unique information about high-energy processes in the universe. Numerous sources for the EGRB have been proposed, but the
Cosmic γ-ray background from structure formation in the intergalactic medium
The Universe is filled with a diffuse background of γ-ray radiation, the origin of which remains one of the unsolved puzzles of cosmology. Less than one-quarter of the γ-ray flux can be attributed to

We examine the properties of the gamma-ray active galactic nuclei (AGNs) detected by EGRET. We calculate the evolution and luminosity function of the gamma-ray-loud AGNs, and we estimate the
