Discovery of evolving low-frequency QPOs in hard X-rays ( $\sim 100$ keV) observed in black hole Swift J1727.8-1613 with $A s t r o S a t$

Anuj Nandi, Santabrata Das, Seshadri Majumder +3

We report the first detection of evolving Low-Frequency Quasi-periodic Oscillation (LFQPO) frequencies in hard X-rays upto $100$ keV with $A s t r o S a t / L A X P C$ during `unusual' outburst…

Unveiling the accretion scenario of BH-ULXs using XMM-Newton observations

Seshadri Majumder, Santabrata Das, Vivek. K. Agrawal +1

We present a comprehensive spectro-temporal analysis of five ultraluminous X-ray sources (ULXs) with central object likely being a black hole, using archival {\it XMM-Newton} obser…
