  • Temporal and spectral characteristics of active galactic nuclei in X-rays using NuSTAR 
    Priyanka Rani (Indian Institute of Astrophysics, 2019-02)
    Flux variability is one of the defining characteristics of active galactic nuclei (AGN). This has been known over the past six decades ever since the discov- ery of quasars in 1963. Since then AGN have been observed ...
  • X-ray flux variability of active galactic nuclei observed using NuSTAR 
    Priyanka Rani; Stalin, C. S; Rakshit, S (Oxford University Press on behalf of the Royal Astronomical Society, 2017-04)
    We present results of a systematic study of flux variability on hourly time-scales in a large sample of active galactic nuclei (AGN) in the 3−79 keV band using data from Nuclear Spectroscopic Telescope Array. Our sample ...
