We are excited to present the 15th edition of our (fully virtual) colloquium series!
Here, we will celebrate the research and leadership by Indian women Astronomers and Cosmologists across the globe.

Abstract: Compact accreting binaries hosting neutron stars and black holes exhibit rich variability over timescales from milliseconds to years, providing powerful probes of accretion physics, inner-disc instabilities, and jet formation under extreme conditions. In this talk, I will present recent X-ray timing and broadband spectral studies of low-mass X-ray binaries using AstroSat, NICER, and NuSTAR, and coordinated multi-wavelength observations spanning X-ray, optical, ultraviolet, and radio bands. I will discuss correlated variability, quasi-periodic oscillations, thermonuclear bursts, and jet-related behaviour in systems including accreting millisecond pulsars. I will also highlight recent results on fast X-ray transients discovered with Einstein Probe, emphasizing the growing importance of wide-field monitoring and rapid follow-up in time-domain astrophysics. Finally, I will discuss how upcoming/new facilities such as Vera C. Rubin Observatory/LSST, XRISM, NewAthena, and Square Kilometre Array will transform our understanding of the dynamic high-energy Universe.
