AstroSat timing and spectral analysis of the accretion-powered millisecond X-ray pulsar IGR J17591--2342

Akshay Singh, Andrea Sanna, Sudip Bhattacharyya +5

IGR J17591--2342, a transient accretion-powered millisecond X-ray pulsar, was discovered during its 2018 outburst. Here, we present a timing and spectral analysis of the source usi…

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…
