Multi-wavelength analysis of FSRQ B2 1348+30B: Constraints on the jet power
Sajad Ahanger, Sunder Sahayanathan, Sitha K. Jagan +2
We present 14.5-year multi-wavelength analysis of flat-spectrum radio quasar B2 1348+30B using Swift-UVOT, Swift-XRT, and Fermi-LAT observations. In the gamma-ray band, the 3 day b…
Statistical Insights into Flux and Photon Index Distributions of VHE FSRQs from Fermi-LAT Observations
Zahoor Malik, Sikandar Akbar, Zahir Shah +8
This study examines the flux and photon index distributions of 11 Very High Energy (VHE) Flat Spectrum Radio Quasars (FSRQs) using over 16 years of Fermi-LAT -ray data. The dist…
Study of Multi-Wavelength Variability, Emission Mechanism and Quasi-Periodic Oscillation for Transition Blazar S5 1803+784
Javaid Tantry, Ajay Sharma, Zahir Shah +2
This work present the results of a multi-epoch observational study of the blazar S5\,1803+784, carried out from 2019 to 2023. The analysis is based on simultaneous data obtained fr…
Probing Broadband Spectral Energy Distribution and Variability of Mrk\,501 in the low flux state
Javaid Tantry, Zahir Shah, Ranjeev Misra +2
We conducted a multi-wavelength analysis of the blazar Mrk\,501, utilizing observations from \emph{Astro}Sat (SXT, LAXPC), \emph{Swift-UVOT}, and \emph{Fermi-LAT} during the period…
Understanding the Very High Energy γ-ray excess in nearby blazars using leptonic model
Aaqib Manzoor, Sunder Sahayanathan, Zahir Shah +3
The availability of simultaneous X-ray and Very High Energy (VHE) observations of blazars helps to identify the plausible radiative contributors to the VHE emission. Under leptonic…
