Insights into the Long-Term Flaring Events of Blazar PKS 0805-07: A Multi-Wavelength Analysis over the 2009-2023 Period
Sikandar A. Dar, Zahir Shah, Ranjeev Misra +1
We conducted a comprehensive temporal and spectral study of the FSRQ PKS 0805-07 by using the broadband observations from the Fermi-LAT and Swift-XRT/UVOT instruments over the peri…
Spectro-temporal evolution of 4U 1702-429 using AstroSat-NICER
Suchismito Chattopadhyay, Ranjeev Misra, Soma Mandal +2
We present the broadband spectral and timing properties of the atoll source 4U 1702-429 using two observations of AstroSat with the second one having simultaneous NICER data. For b…
Probing Broadband Spectral Energy Distribution and Variability of Mrk\,501 in the low flux state
Javaid Tantry, Zahir Shah, Ranjeev Misra +2
We conducted a multi-wavelength analysis of the blazar Mrk\,501, utilizing observations from \emph{Astro}Sat (SXT, LAXPC), \emph{Swift-UVOT}, and \emph{Fermi-LAT} during the period…
Multi-wavelength study of extreme high-energy peaked BL Lac (EHBL) source 1ES 0229200 using ultraviolet, X-ray and gamma-ray observations
Jyotishree Hota, Rukaiya Khatoon, Ranjeev Misra +1
We present a comprehensive analysis of the broadband spectral energy distribution (SED) of the extreme high-energy peaked BL Lac (EHBL) source, 1ES 0229200. Our study utilizes n…
Modelling the Energy-dependent broadband variability in the black-hole transient GX 339-4 using Astrosat and NICER
Hitesh Tanenia, Akash Garg, Ranjeev Misra +1
We present a spectro-timing analysis of the black hole X-ray transient GX 339-4 using simultaneous observations from Astrosat and NICER during the 2021 outburst period. The combine…
Exploring the broadband spectral and timing characteristics of GRS 1915+105 with AstroSat and NICER observations
Ruchika Dhaka, Ranjeev Misra, JS Yadav +1
In this study, we undertake a spectral-timing analysis of the black hole X-ray binary source GRS 1915+105 using simultaneous observations carried out by AstroSat (LAXPC and SXT) an…
