To understand the nature of star formation in dwarf galaxies astronomers researchers from Aryabhatta Research Institute of Observational Sciences (ARIES) observed many such galaxies using the 1.3-meter Devasthal Fast Optical Telescope (DFOT) near Nainital and the Giant Meter wave Radio Telescope (GMRT).
- Aryabhatta Research Institute of Observational Sciences (ARIES) is an autonomous institute of Department of Science & Technology (DST), Govt. of India
- While the former operated at optical wavelengths sensitive to detect optical line radiation emanating from the ionized Hydrogen, in the latter 30 dishes of 45-meter diameter, each worked in tandem and produced sharp interferometric images via spectral line radiation at 1420.40 MHz coming from the neutral Hydrogen in galaxies.
- Star formation at a high rate requires very high density of Hydrogen in the galaxies.
