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 ...
X-ray polarization observations of IC 4329A with IXPE: Constraining the geometry of the X-ray corona

Pal, Indrani; Stalin, C. S; Chatterjee, Rwitika; Agrawal, Vivek K (Indian Academy of Sciences, 2023-12)

X-ray polarimetry is a powerful tool to probe the geometry of the hot X-ray corona in active galactic nuclei (AGN). Here, we present our results on the characterisation of the X-ray polarization of the radio-quiet Seyfert-type ...
X-ray spectral and timing analysis of the Compton Thick Seyfert 2 galaxy NGC 1068

Pal, Indrani; Stalin, C. S; Parker, M. L; Agrawal, Vivek K; Marchesi, S (Oxford University Press on behalf of Royal Astronomical Society, 2022-12)

We present the timing and spectral analysis of the Compton Thick Seyfert 2 active galactic nuclei NGC 1068 observed using NuSTAR and XMM–Newton. In this work for the first time we calculated the coronal temperature (⁠kTekTe⁠) ...
