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 via…
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…
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 ma…
Is Gamma-ray Burst 221009A Really a Once-in-10,000 Year Event?
Justin Finke, Soebur Razzaque
Gamma-ray bursts (GRBs) brighter than the GRB 221009A, the brightest yet observed, have previously been estimated to occur at a rate of 1 per 10,000 years, based on the extrapolati…
Influence of Cosmic Voids on the propagation of TeV Gamma Rays and the Puzzle of GRB 221009A
Hassan Abdalla, Soebur Razzaque, Markus Böttcher +2
The recent detection of gamma-ray burst GRB~221009A has attracted attention due to its record brightness and first-ever detection of TeV rays from a GRB. Despite b…
Constraints on redshifts of blazars from extragalactic background light attenuation using Fermi-LAT data
A. Domínguez, M. Láinez, V. S. Paliya +6
The extragalactic high-energy -ray sky is dominated by blazars, which are active galactic nuclei with their jets pointing towards us. Distance measurements are of fundamental im…
