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…
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…
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…
Long-term XMM-Newton view of magnetar CXOU J010043.1721134: Comprehensive spectral and temporal results
Rwitika Chatterjee, Vivek K. Agrawal, Anuj Nandi
We present an in-depth analysis and results of eleven XMM-Newton datasets, spanning 2000 to 2016, of the anomalous X-ray Pulsar CXOU J010043.1721134 which has been classified as…
A Machine Learning approach for classification of accretion states of Black hole binaries
H Sreehari, Anuj Nandi
In this paper, we employ Machine Learning algorithms on multi-mission observations for the classification of accretion states of outbursting Black hole X-ray binaries for the first…
Multiwavelength monitoring of NGC 1275 over a decade: Evidence of a shift in synchrotron peak frequency and long-term multi-band flux increase
Sanna Gulati, Debbijoy Bhattacharya, Subir Bhattacharyya +3
We carried out a detailed study of the temporal and broadband spectral behaviour of one of the brightest misaligned active galaxies in gamma-rays, NGC 1275 utilising 11 years of Fe…
