- Observation studies of the timing and spectral properties of compact objects, such as black
holes, neutron stars, white dwarfs during their active phases using data of astronomy
satellites including India’s first multi-wavelength satellite AstroSat.
- Estimation of intrinsic source parameters, such as mass, spin, distance, disk inclination
angle, etc. of the black holes.
- Studying the nature of Gravity waves due to merger of compact objects. Future India’s
dedicated mission LIGO-India data will also be used for our study in this work.
- Theoretical improvement of the existing models or introduction of the new models to study
both spectral and temporal properties of the compact X-Ray binaries.
- Understanding the outburst nature of compact objects by studying their both short and long
term variations. Studying the trigger mechanisms, duration, peak flux variations in outbursts
of transient X-ray binaries.
- Studying nature of short and long term Gamma ray bursts (GRBs) and its afterglows using
multi-wavelength data of space and ground based satellites / instruments / telescopes.
- Studying solar activities (solar flares, coronal mass ejections, solar winds, etc.) using X-ray
data of different astronomy satellites. Impact of magnetic instabilities and reconnection of the
solar surface will be studied. These studies will also help us to understand the nature of the
companion star of X-ray binaries.
- Involvement in space instrumentation projects to observe high energetic events or
phenomena in collaboration with ISRO or other International space agencies.
