At low Σg, galaxies have low fcal at all energies E because there are few targets for hadronic collisions with CRs. As Σg increases, the increased ISM density results in efficient calorimetry and conversion of CR energy into γ-rays for low CR energies; however, at higher energies the ...
Direct measurements of the EBL are very difficult due to the intense zodiacal light and the Galactic foreground emission. High-energy gamma rays may interact with photons of the EBL and generate positron-electron pairs. This introduces an attenuation feature in the spectra of distant gamma-ray ...
The SFRD is intimately connected with the extragalactic background light (EBL), i.e., the diffuse meta-galactic photon field in the ultraviolet to infrared, which is dominated by the emission from stars in galaxies. Directly measuring the EBL is difficult due to dominant foreground emission in ...

Gamma-rays from extragalactic sources at cosmological distances (blazars and gamma-ray bursts) interact with EBL photons creating electron-positron pairs, absorbing the gamma-rays. Given the intrinsic gamma-ray spectrum of a source and its redshift, the EBL can in principle be measured. However, ...

For the spectrum with Texp=1 ks, the average systematic errors in 1−7 keV and 1−10 keV are 4.2% and 3.7%, respectively. We also perform the systematic error analyses of the background light curves with different energy bands and time bins. The results show that the systematic ...
