A Possible Short-Timescale Optical Quasi-Periodic Oscillation in PKS\,0805 $-$ 07 from High-Cadence TESS Observations

Sikandar Akbar, Zahir Shah, Athar A. Dar +1

We present a timing analysis of the high-cadence optical light curve of the high-redshift flat-spectrum radio quasar PKS\,0805 $-$ 07 obtained during \textit{TESS} Sector~34 (MJD~=~5…

Broadband Variability Analysis of FSRQ PKS\,0402-362 with Indications of Quasi-Periodic Modulation

Zeeshan Nazir, Sikandar Akbar, Zahir Shah +2

We present a comprehensive temporal and spectral study of the flat-spectrum radio quasar PKS~0402 $-$ 362 using \textit{Fermi}-LAT/Swift-XRT/UVOT observations spanning from MJD 54686…
