Mineral dust, biomass burning, secondary sulfate, secondary nitrate from northwest India and Pakistan polluted cities like Delhi, the Thar Desert, and the Arabian Sea area, and long-range transported marine-mixed aerosols are the main sources of aerosols in the central Himalayan region, said the Ministry of Science and Technology which shared the findings of the study.This dust transport and forest fires are the main sources of TSP particularly in pre-monsoon period March-May when TSP concentration peaks in the region, it said.

Mineral dust (34 per cent) and biomass burning (27 per cent) are among the main sources of aerosols in the central Himalayan region, a new study has shown.Along with mineral dust and biomass burning, secondary sulphate, secondary nitrate from ...

In Depth: Indian Astronomers Contribute To Discovery Of Shortest Gamma-Ray Burst Ever Recorded From A Dying Star by Karan Kamble - Jul 29, 2021 12:30 AM Gamma-ray burst illustration (Wikimedia Commons) Snapshot Shooting towards Earth for as long as nearly half the present age of the universe, the burst or signal is said to have beeped for less than a second — short, yet enough to make its powerful presence felt. The detection challenges astronomers' current understanding of gamma-ray bursts and where they come from. A whisper of an extraordinary cosmic event reached our Earthly ear last ...

Indian astronomers with other scientists spot unique Gamma-ray burst The burst detected by NASA's Fermi Gamma-ray Space Telescope on August 26, 2020, turned out to be one for the record books -- the shortest Gamma-ray burst (GRB) caused by the death of a massive star. New Delhi: A group of astronomers, few of them Indians, have detected a very short, powerful burst of high-energy radiation that lasted for about a second and had been racing towards Earth for nearly half the present age of the universe. The burst detected by NASA's Fermi Gamma-ray Space Telescope on August 26, 2020, turned out ...
