Investigating the disappearance of a type-C QPO in black hole X-ray binary Swift J151857-572147 with AstroSat
Biki Ram, Manoneeta Chakraborty, Mayukh Pahari
We present a timing and broadband spectral study of the AstroSat observation of the black hole low mass X-ray binary Swift J151857.0--572147, focusing on its evolution across two t…
Study of UV line and continuum variabilities in the Broadline Seyfert 1 Galaxy ESO 141-G55
Mayukh Pahari, Veda Samhita, Harikumar N. +2
We present the results from a 3-year-long Ultraviolet monitoring campaign of the broad line Seyfert 1 galaxy ESO 141-G55 using International Ultraviolet Explorer (IUE). By modellin…
Black hole-Neutron star distinction based on long-term MAXI and Swift study of 42 low mass X-ray binaries
Prakhar Maheshwari, Mayukh Pahari, Anish Sarkar +1
In this study, we analysed about 13 years of publicly available data from MAXI and Swift/BAT to examine the long-term source evolution of 42 transient low-mass X-ray binaries…
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…
Measuring accretion disc properties in the transitional millisecond pulsar PSR J1023+0038 using XMM-Newton, NuSTAR, NICER and Chandra
Vishal Jadoliya, Mayukh Pahari, Sudip Bhattacharyya +1
Whether the accretion disc in the X-ray high-mode of transitional millisecond pulsars (tMSP) reaches near the neutron star surface by penetrating the magnetosphere is a crucial que…
