Swift J1753.5-0127 : Understanding the accretion geometry through frequency resolved spectroscopy
Blessy E. Baby, Ramadevi M. C
The Black Hole Binary source Swift J175.5-0127 remained in outburst for 12 years from May 2005 to April 2017. For most part of the outburst, the source remained in the Low H…
The upcoming 4m ILMT facility and data reduction pipeline testing
Brajesh Kumar, Vibhore Negi, Bhavya Ailawadhi +5
The 4m International Liquid Mirror Telescope (ILMT) installation activities have recently been completed at the Devasthal observatory (Uttarakhand, India). The ILMT will perform co…
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…
Investigating the coronal structure by studying time lags in the Atoll source 4U 1705-44 using AstroSat
S. Malu, S. Harikrishna, K. Sriram +1
We performed a detailed timing study of the Atoll source 4U 1705-44 in order to understand the accretion disk geometry. Cross correlation function (CCF) studies were performed betw…
Relativistic viscous accretion flow model for ULX sources: A case study for IC 342 X-1
Santabrata Das, Anuj Nandi, Vivek K. Agrawal +2
In this letter, we develop a model formalism to study the structure of a relativistic, viscous, optically thin, advective accretion flow around a rotating black hole in presence of…
AstroSat and MAXI view of Cygnus X-1: Signature of an `extreme' soft nature
Ankur Kushwaha, V. K. Agrawal, Anuj Nandi
We present a detailed spectral and timing analysis of Cygnus X-1 with multi-epoch observations, during to , by SXT and LAXPC on-board AstroSat. We model the spectra in…
