Bridging X-ray Polarization with Timing & Spectroscopic Parameters of a galactic black hole: Swift J1727.8-1613
Arka Chatterjee, Sujoy K. Nath, Kaushik Chatterjee +5
We report the discovery of a correlated energy-dependent time lag and degree of polarization for Swift J1727.8-1613 during its 2023 outburst. The energy-dependent time lag is measu…

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 (, , and spectral variability classes) of the black hole binary GRS 1915+105, using RXTE, AstroSat, a…
