Mystery behind rapid star formation in Dwarf galaxies - Dr. Amitesh Omar

Описание: ARIES astronomers trace the mystery behind dwarf galaxy aberrations of massive star formation.
To understand the nature of star formation in dwarf galaxies astronomers Dr. Amitesh Omar and his former student Dr. Sumit Jaiswal from Aryabhatta Research Institute of Observational Sciences (ARIES), an autonomous institute of Department of Science & Technology (DST), Govt. of India observed many such galaxies using the 1.3-meter Devasthal Fast Optical Telescope (DFOT) near Nainital and the Giant Meter wave Radio Telescope (GMRT). 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.
