Aryabhatta Research Institute of Observational Sciences (ARIES)

About Us

The Aryabhatta Research Institute of Observational Sciences (ARIES) is a research institute located in Nainital, Uttarakhand, India.
It specializes in various fields, including astronomy, solar physics, and atmospheric science.
Research activities at ARIES include solar astronomy, stellar astronomy, star clusters, stellar variability and pulsation, photometric studies of nearby galaxies, quasars, and transient events like supernovas and highly energetic gamma-ray bursts.

              Structure:
              The astronomy division comprises a dynamic assembly of scientists, postdoctoral researchers, and doctoral candidates. 
              The division focuses on optical and near-infrared studies of celestial sources; however, to get a comprehensive knowledge of celestial events in astrophysical contexts, 
              the researchers also employ data from electromagnetic radiation, gravitational waves, neutrinos, and cosmic rays. Analytical investigations and numerical simulations of 
              jets and accretion disks related to black holes are also conducted. The department also possesses a solar astronomy group.
