Adaptive Optics (AO) is a real time wave-front correction technique, through which the light coming from the stars can be corrected for the effects of atmospheric turbulence. This enables the ground based telescope to reach ...

Low frequency radio observations of the solar corona provide valuable information on the heliocentric distance range ≈ 1.1R - 3R , which is relatively difficult to observe from other wavelengths. These observations are ...

Polarimetric observations of celestial objects reveal information regarding magnetic field, scattered dust and planetary atmosphere. The degree of po- larization, which is of interest to astronomers, ranges from ...

We describe the development of compact, lightweight payloads suitable for ground, space, and balloon-based observatories. The first instrument is a compact high resolution (≥ 20000) tunable spatial heterodyne spectrom- eter ...

Adaptive Optics (AO) technology is a part of ground-based astronomical observatories around the world. It enables the telescopes to attain near diffraction-limited resolution. We have designed, developed and tested a ...

At Indian Institute of Astrophysics, we conduct high altitude balloon ex- periments for atmospheric and astronomical observations in UV wavelength range. To carry out observations of astronomical sources, a fine pointing ...

Active galactic nuclei (AGN) are the persistent high luminosity sources powered by accretion of matter onto super massive black holes (SMBHs) at their centres. They are known to show flux variation and this property can ...
