Revealing the nature of the transient source MAXI J0637-430 through spectro-temporal analysis
Blessy E. Baby, Bhuvana G. R., Radhika D. +3
We study the spectral and temporal properties of MAXI J0637-430 during its 2019-2020 outburst using \textit{NICER}, \textit{AstroSat} and \textit{Swift-XRT} data. The source was in…
Multi-mission view of extragalactic black hole X-ray binaries LMC X-1 and LMC X-3: evolution of broadband spectral features
Bhuvana G. R., Radhika D., Anuj Nandi
Extragalactic black hole X-ray binaries LMC X-1 and LMC X-3 are the persistent sources, usually found in soft spectral state. We present the results from spectral and timing study…
Broadband 'spectro-temporal' features of extragalactic black hole binaries LMC X-1 and LMC X-3: An AstroSat perspective
Bhuvana G. R., Radhika D., V. K. Agrawal +2
We present the first results of extragalactic black hole X-ray binaries LMC X-1 and LMC X-3 using all the archival and legacy observations by AstroSat during the period of $2016-20…
Constraining the mass of the black hole GX 339-4 using spectro-temporal analysis of multiple outbursts
Sreehari H., Nirmal Iyer, Radhika D. +2
We carried out spectro-temporal analysis of the archived data from multiple outbursts spanning over the last two decades from the black hole X-ray binary GX 339-4. In this paper, t…
Broad-band spectral evolution and temporal variability of IGR J17091-3624 during its 2016 outburst : SWIFT and NuSTAR results
