AstroSat, India's first multi-wavelength space observatory is an unique platform to observe cosmic X-ray sources, especially to probe the strong gravity of 'compact' objects. I will discuss the capabilities of AstroSat and present some interesting results to decipher the environment around the 'compact' objects.

Since the Nobel winning discovery of gravitational waves (GWs) by the LIGO-Virgo-Kagra (LVK) detectors from merging compact object binaries, understanding the various astrophysical formation channels of these sources has come to sharp focus. While qualitatively, the processes involved in producing these astrophysical systems are well understood, cutting-edge research is underway to put better...

X-rays are the signatures of the high-energy Universe. The X-ray band probes extreme environments in the Universe, such as those near black holes or the surface of neutron stars. Observations in X-ray energies of the sky provides the opportunity to study such exotic objects in the Universe, allowing the exploration of physical processes in extreme conditions. Many space missions and...
