A TeV-based Determination of the Local Extragalactic Background Light and its Consistency with Galaxy Counts and Direct Measurements
J. Baxter, A. Dominguez, J. D. Finke +5
The extragalactic background light (EBL), the cumulative radiation from all extragalactic sources, traces galaxy formation and cosmic evolution. High-energy rays attenuated vi…
A New Measurement of the Extragalactic Background Light using 15\,yr of {\it Fermi}-Large Area Telescope Data
Anuvab Banerjee, Justin D. Finke, Marco Ajello +5
The extragalactic background Light (EBL) from ultraviolet to infrared comprises the emission from all stars, galaxies, and actively accreting black holes in the observable Universe…
The gamma-ray emission from Radio Galaxies and their contribution to the Isotropic Gamma-Ray Background
A. Circiello, A. McDaniel, M. Di Mauro +6
We evaluate the contribution to the Isotropic Gamma-Ray Background (IGRB) coming from Radio Galaxies (RGs), the subclass of radio-loud Active Galactic Nuclei (AGN) with the highest…
A multi-wavelength view of the multi-messenger sources NGC 1068 and PKS 1502+1061
Abhishek Desai, Stefano Marchesi, Justin Vandenbroucke +8
Multi-messenger astronomy offers a powerful approach to studying high-energy radiative processes in astrophysical sources. A notable example was seen in 2017, when the IceCube Neut…
