Spectro-timing origin of large amplitude X-ray variability in GRS 1915+105 using AstroSat/LAXPC and SXT
Shree Suman, Shuvajit Khatua, Vishal Jadoliya +2
The origin of the large-amplitude, quasi-periodic X-ray flux variations in several classes of the Galactic microquasar GRS~1915+105 remains unresolved. We address this issue throug…

Understanding coronal geometry in NGC 4593 using Fourier frequency-resolved covariance and time-lag spectral analysis
Shree Suman, Mayukh Pahari, Gulab Dewangan +1
Understanding disc-corona geometry through X-ray reverberation variability studies in Seyfert galaxies is crucial, yet our knowledge mostly relies on flux-averaged mean spectral an…
