Wide-band view of High Frequency QPOs of GRS 1915+105 in 'softer' variability classes observed with AstroSat
Seshadri Majumder, H. Sreehari, Nafisa Aftab +3
We present a comprehensive temporal and spectral analysis of the 'softer' variability classes (, , , , , , and ) of the source GRS 1915+105 observed by…
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…
AstroSat view of GRS 1915+105 during the Soft State: Detection of HFQPOs and estimation of Mass and Spin
Sreehari H., Anuj Nandi, Santabrata Das +4
We report the results of AstroSat observations of GRS 1915105 obtained using 100 ks guaranteed-time (GT) during the soft state. The Color-Color Diagram (CCD) indicates a variabi…
AstroSat view of MAXI J1535-571: broadband spectro-temporal features
Sreehari H., Ravishankar B. T., Nirmal Iyer +4
We present the results of Target of Opportunity (ToO) observations made with AstroSat of the newly discovered black hole binary MAXI J1535-571. We detect prominent C-type Quasi-per…
Study of the long-term evolution of the accretion dynamics of GX 339-4
U. Aneesha, S. Mandal, H. Sreehari
We study the dynamical behaviour of the galactic black hole source GX 339-4 during 2002-2011 outbursts using RXTE, Swift(XRT), XMM-Newton(PN) archival data. We present the spectral…
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…
