Possible detection of HFQPOs associated with 'unknown' variability class of GRS 1915+105

Seshadri Majumder, Santabrata Das, Anuj Nandi

We present a comprehensive spectro-temporal analysis of GRS $1915 + 105$ observed with AstroSat during June, $2017$ . A detailed study of the temporal properties reveals the appearanc…

Revisiting Disc-Jet Coupling in Black Hole X-ray Binaries: On the Nature of Disc Dynamics and Jet Velocity

Sreetama Das Choudhury, Bhuvana G. R., Santabrata Das +1

We perform a comprehensive wide-band ( $3 - 100$ keV) spectro-temporal analysis of 13 outbursting BH-XRBs, using data (quasi)simultaneous with radio observations to unravel the complex…

Probing the accretion geometry of black hole X-ray binaries: A multi-mission spectro-polarimetric and timing study

Seshadri Majumder, Ankur Kushwaha, Swapnil Singh +3

We present a comprehensive spectro-polarimetric and timing analysis of twelve black hole X-ray binaries, namely Cyg X-1, 4U 1630-47, Cyg X-3, LMC X-1, 4U 1957+115, LMC X-3, Swift J…

Evidence of oscillating `compact' Comptonized corona in GRS 1915+105: Insights into HFQPOs with AstroSat

Sreehari Harikesh, Seshadri Majumder, Santabrata Das +1

We present, for the first time, an in-depth dynamical analysis of the spectro-temporal properties of the soft variability classes ( $δ$ , $κ$ , $ω$ , and $γ$ ) of GRS 1915+105 during th…

Decoding the Origin of HFQPOs of GRS 1915+105 during 'Canonical' Soft States: An In-depth View using Multi-mission observations

Prajjwal Majumder, Broja G. Dutta, Anuj Nandi

We present a comprehensive analysis of the 'canonical' soft state ( $γ$ , $δ$ , and $ϕ$ spectral variability classes) of the black hole binary GRS 1915+105, using RXTE, AstroSat, and…

Long-term evolution of BH-ULX candidates: An `unusual' $L_{disc}$ - $T_{col}$ correlation associated with spectral states

Seshadri Majumder, Santabrata Das, Anuj Nandi

We present the long-term spectral evolution of eight black hole ultra-luminous X-ray sources (BH-ULXs), namely NGC1313 X-1, NGC5408 X-1, NGC6946 X-1, IC342 X-1, NGC55 ULX1, NGC4395…
