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…
Investigating Active Galactic Nuclei variability with the Cherenkov Telescope Array Observatory
G. Grolleron, J. Biteau, M. Cerruti +21
Blazars, a type of active galactic nuclei (AGN) with relativistic jets pointed at the observer, exhibit flux variability across the electromagnetic spectrum due to particle acceler…
Solar Gamma-Ray Evidence for a Distinct Population of 1 MeV Flare-Accelerated Electrons
Gerald H. Share, Ronald J. Murphy, Brian R. Dennis +1
Significant improvements in our understanding of nuclear -ray line production and instrument performance allow us to better characterize the continuum emission from electrons a…
A Synthetic Population of Ultra-Luminous X-ray Sources: Optical-X-ray Correlation
Lutendo Nyadzani, Soebur Razzaque, Justin D. Finke
This paper presents an analysis of the predicted optical-to-X-ray spectral index () within the context of ultra-luminous X-ray sources (ULXs) associated with stellar m…
