Probing the High-Energy Emission of the VHE-emitting Changing-Look Blazar B2 1420+32
Anjum Peer, Zahir Shah, Sikandar Akbar +2
We present a multi-wavelength temporal and spectral study of the changing-look blazar B2~1420+32 using \emph{Fermi}-LAT, \emph{Swift}-XRT, and \emph{Swift}-UVOT data from MJD~58818…

Generation and Detection of Hyperentangled Bell States at an Ultra-High Flux
Netanel P. Yaish, Samata Gokhale, Avi Peer
We demonstrate both the generation and detection of an ultra-high flux of polarization Bell states using broadband hyper-entangled bi-photons that are quantum-correlated in both po…

Comprehensive Variability Analysis of Blazars Using Fermi Light Curves Across Multiple Timescales
Zahir Shah, Athar A. Dar, Sikandar Akbar +8
In this study, we conducted a systematic analysis of long-term Fermi-LAT γ-ray data for a sample of blazars, including FSRQs, BL\,Lacs, and BCUs, to investigate their -ray var…
