GMRT measures the atomic hydrogen gas mass in galaxies 9 billion years ago

A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR) in Pune, and the Raman Research Institute (RRI), in Bangalore, has used the Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen gas content of galaxies 9 billion years ago, in the young universe. This is the earliest epoch in the universe for which there is a measurement of the atomic hydrogen content of galaxies. The new result is a crucial [...]

uGMRT reveals for the first time the patchy environment of a rare cosmic explosion

Scientists from the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR), Pune used the upgraded Giant Metrewave Radio Telescope (uGMRT) to determine that AT 2018cow, the first of a newly discovered class of cosmic explosions, has an extremely patchy environment. Sources like AT 2018cow release an enormous amount of energy, nonetheless fade extremely rapidly. This along with their extremely blue color [...]

Plastic electronics: Ushering in the next generation of technology

A team of researchers from multiple institutions, led by Pabitra Nayak from the Tata Institute of Fundamental Research, Hyderabad, have successfully come up with a novel way of transforming an otherwise less-conducting organic material into an efficient conductor of electricity for electronic application. This paves the way for development of cost-effective, structurally and functionally amenable semiconductor devices, thus marking the dawn of a [...]

Origins and probes of unusually light black holes

In recent years, gravitational wave observatories have detected mergers of compact astrophysical objects with low masses, at best a few times that of the Sun. The identities of these objects remain unclear. If indeed these are black holes, these would be the lightest black holes yet detected. As the search for low mass objects continues, if even lower mass black holes are seen, understanding their origin will pose a fundamental challenge to known [...]

CO2 Mitigation on Earth and Magnesium Civilization on Mars

Excessive CO2 emissions are a major cause of climate change, and hence reducing the CO2 levels in the Earth’s atmosphere is key to limit adverse environmental effects. Prof. Vivek Polshettiwar's group at Tata Institute of Fundamental Research (TIFR), Mumbai, employed magnesium to convert CO2 to methane, methanol and formic acid, using water as the sole hydrogen source. The conversion of CO2 (or air) took place within a few minutes at ambient [...]
