Accretion dynamics and coronal geometry in Mrk 530: Insights from 24 years of X-ray monitoring
Priyadarshee P. Dash, Prantik Nandi, Sachindra Naik +2
We present a long-term broadband study of the Seyfert galaxy Mrk~530 spanning 24 yr (2001--2024). The source remains largely stable across epochs, except in 2018, when a poss…
Revisiting the Orbital Dynamics of the Hot Jupiter WASP-12 b with New Transit Times
Shraddha Biswas, Ing-Guey Jiang, Li-Chin Yeh +10
In this study, we examine the transit timing deviations of the extensively studied hot Jupiter WASP-12 b using a comprehensive dataset of 391 transit light curves. The dataset incl…
Numerical study of multiple solar flare induced modulation of Very Low Frequency (VLF) diurnal profile
Sourav Palit, Subhajit Bhattacharyya, Taraknath Bera +1
Earth's ionosphere is a perpetual detector of ionizing radiation received from celestial objects, particularly the Sun. Solar ionizing radiation in the form of extreme ultraviolet…
Evolution of Accretion Properties in Mrk 1040 using long-term X-ray Observations
Prantik Nandi, Narendranath Layek, Sandip K Chakrabarti +2
We present a comprehensive long-term, multi-epoch spectral and timing study of the Seyfert 1 Active Galactic Nucleus (AGN) Mrk~1040, utilizing X-ray observations spanning from 2009…
