Galactic and extragalactic sources of very high energy gamma rays

The European Physical Journal Special Topics, 2022
Very high energy $$\gamma $$ γ -rays are one of the most important messengers of the relativistic non-thermal Universe. The major motivation of very high energy $$\gamma $$ γ -ray astronomy is to find sources of high energy cosmic rays.

Dust scattered radiation in the galactic poles

Journal of astrophysics and astronomy, 2023
We have modeled the diffuse background at the Galactic Poles in the far-ultraviolet (FUV: 1536 Å) and the near-ultraviolet (NUV: 2316 Å). The background is well-fit using a single-scattering dust model with an offset representing the extragalactic light ...
